Determine the amount of heat generated inside the equipment. 2. From the equipment manufacturer s data, find the maximum permissible equipment temperature. Then, we get the following equations: Air Flow in CFM =.16 x P = 1.76 x P Tf Tc.9 x P.5 x P Air Flow in m /min= = Tf Tc. Calculate the air volume necessary from the equation. 4. Select the fan from the performance curves shown in the fan specification sheets. The volume of airflow required to cool the equipment can be determined if the internal heat dissipation and the total allowable temperature rise are known. The basic heat transfer equation is: P : Internal power dissipation in watts Tf: Allowable temperature rise in ºF Tc: Allowable temperature rise in ºC T : T2-T1 T2 E QUIPMENT POWER DISSIPATION IN WATTS T1 Where: Q = Amount of heat transferred Q = Cp x W x T T1: Incoming airflow temperature T2: Outgoing airflow temperature 1 m / min = 5.15 CFM (Cubic Feet / Min) Cp = Specific heat of air T = Temperature rise within the cabinet W = Mass flow = CFM x D (Where: D= Air Density and CFM is cubic feet / min ) By substitution, we obtain: Q Air Flow in CFM = Cp x D x T COOLING OF HEAT GENERATING EQUIPMENT Example 1: If internal power dissipation is 15W and T is 5 ºF Air Flow in CFM=. 1 6 x 1 5 = 94.8 CFM (or 2.68 m / min) 5 Example 2: If internal power dissipation is 1W and T is 2 ºC Air Flow in m /min =.5 x 1 2 = 2.5 m / min (or 88.

6 HOW TO MEASURE THE IMPEDANCE OF YOUR SYSTEM The measurement of the system's impedance and the selection of the appropriate fan can be illustrated by the following example: Let us use blower series 2 with the following PQ characteristics: B. Refer to the PQ characteristics of the blower to determine the static pressure of your system at the measured airflow. The pressure can be determined from the PQ graph to be 6 mmaq, for the calculated airflow in A of 45 CFM. P2YBACB7b PQ Characteristics Static Pressure (mmaq) P/Q GRAPH C. From the temperature specifications of your equipment, calculate the temperature difference T2-T1 where: T1 is the typical room temperature (e.g. 25 C) and T2 is the maximum allowable operating temperature of equipment (e.g. 6 C). Therefore, T2-T1=5 C. Assuming that you are powering your system with 1W, necessary airflow can be calculated using the formula shown in A as follows: AIR FLOW (CFM) Airflow in CFM = 1.76 x 1 = 5. CFM 5 A. Calculate the airflow through your system by applying the blower in your system and by measuring the incoming and outgoing airflow temperatures as follows: Airflow in CFM = 1.76 x P T2 - T1 Where: P = Input power into your system (e.g. 1 W) T2 = Outgoing airflow temperature in º C ( e.g ºC) T1 = Incoming airflow temperature in º C ( e.g. 2 ºC) Then, calculate the test result: Air Flow = 45 CFM D. For the purpose of the example used here, the appropriate fan to be selected for this application should be able to deliver minimum of 5. CFM at minimum static pressure of 6mmAq. For safety reasons and to allow for higher room temperature, we can choose model P2Y that can deliver 6 CFM at 6mmAq with 42 RPM, or model P8X that can deliver 58 CFM at 6mmAq with 75 RPM. We can further consider the noise level and product life. In this case model series P8X will be the optimum solution for the system in the above example. (See also SELECTION OF A COOLING FAN. DETERMINING FAN LIFE EXPECTANCY We test units for every fan size, rated voltage, PCB type and maximum speed, in ambient temperature of 9 C. This represents the worst running condition because the units are tested at a temperature of 2 ºC higher than the maximum specified operating temperature for the product. For example, for model series 25, we test units of each: R25H5B (5V, High speed, R type) R25YB (V, Y speed, R type) R25YB (, Y speed, R type) G25YB (, Y speed, G type) G25YB (V, Y speed, G type) The product parameters including running current, RPM, temperature rise, and noise level are measured and recorded before the life test begins. The start date is recorded and the life test begins. The units under test are checked daily or twice a week and the following parameters are set as the criteria of failure: 1 H O U R S Accelerated Test for C1/V Series C1LB C1MB C1HB A. The RPM is less than % of the original. B. The current is increased by %. Degress C C. The fan stops. D. Any abnormal noise due to deformation of the housing or other abnormal noise. The db levels are not measured When failure is observed, the date of the latest previous inspection is recorded. The unit that failed is removed from the oven and is carefully examined to determine the cause of failure, whereas the other 2 units will remain under test until they fail. The life expectancy is then calculated based on the following Acceleration Factor formula: life expectancy at ambient temperature T = 1.65^[(T9-T)/1] which means that the product life is increased by 1.65 times each time the ambient temperature is decreased by 1 C. It must be noted that in industry, the life expectancy is assumed to double for every 1 C ambient temperature decrease according to the formula: Acceleration Factor (AF) = 2^[(Ttest-T)/1]. Our calculation is more conservative. The life expectancy strongly depends on the ambient operating temperature plus the internal temperature rise. The temperature rise of the product is essential in the calculation. The life expectancy also depends on the speed; higher running speed means lower life. The effect of the speed to the life of the measured sample is calculated by 25% reduction of the fan life for every % increase of the speed. In the MTBF calculation, both temperature rise and speed are considered. 1 6 sales@pelonistech.com T F

7 USING PELONIS TECHNOLOGIES SYNCHRONOUS PWM FOR FAN SPEED CONTROL There are different methods to control fan speed. Some PWM speed control techniques and their drawbacks are: A. By changing the regulated DC voltage applied to the fan This is an expensive method because high power must be controlled via a control signal to the regulated power supply. If we change the power supply to the fan in question, it will interfere with the power supply voltage of other equipment. As a result, a dedicated power supply for the fan increases the cost and space occupied by the equipment. B. By applying a PWM signal on a switch The switch can be a MOSFET or BJT transistor which interrupts the fixed DC voltage applied to the fan. This method requires a control signal and powerful switch because the switch must be able to handle the maximum fan current and voltage. In addition to the high cost and increase in space required, proper fan operation is not certain. C. By applying a PWM signal to the fan s SG (Stop and Go) input (if the fan is equipped with a fast responding SG function) This method does not require additional space but is limited in its application for the following reasons: I. Applying a low frequency PWM SG signal The frequency of the PWM signal must be low in the order of 2 to Hz in order to be able to control the fan speed of high power or high voltage fans. The minimum frequency of the low frequency PWM signal must be twice the switching frequency of the coils. Thus, in a 4-pole motor, the minimum applied PWM frequency must be 4 times the rotation frequency of the fan. Increasing this frequency (which must be kept low due to switching losses in high power or high DC voltage fan applications), will result in increased noise. II. Applying a high frequency PWM SG signal If high frequency PWM is used, such as 25KHz, which is not audible and over the human ear response*, we encounter the problems of switching losses in medium or high power DC fan applications and in high voltage DC applications of virtually any power. * The human ear can hear from 2Hz to 2 Khz. However, in reality, most people will hear from 2 Hz to about 1 Khz D. Using Pelonis Technologies Synchronous PWM Synchronous PWM resolves the switching speed problem by internally generating a PWM signal which follows the switching frequency of coils and always remaining synchronous with the switching points of the hall sensor, (see switching diagram in Fig. d). During the switching of the coil(s), the power is applied to the fan and after the switching has occurred the power is interrupted internally and as much as it is required by the external command as shown in Fig. d. The external command can be any of the following: a. A variable resistor b. An NTC thermistor that changes its resistance with the temperature c. A DC voltage signal (typically ~5VDC) d. A current signal that can be terminated to a fixed resistor yielding an input DC voltage signal of to 5 volts. e. A PWM signal in the range of Hz to Khz. Any of the above signals applied to the fan is internally converted to a synchronous PWM signal in order to control the fan speed. Furthermore, due to an internal Phase locked Loop technique, when the required speed is set, the fan will maintain this speed virtually unchanged with a wide variation of the power supply. This is called the CS or Constant function.

8 AVAILABLE FEATURES 1a. IR - Inrush Protection When the power switch is turned on to supply current to the fan, the current is zero and starts to increase gradually until the fan has achieved its maximum speed at the rated current. The maximum current at start up is equal to the free running current (or less in case the rotor is locked at start up). The fan will achieve the rated speed within 5 seconds (see Fig. 1a). 1b. AS - Locked rotor protection and restart with Limit The Auto Start function ensures that the fan will automatically restart when the blade is blocked and then released. When the rotor is locked, the fan current is reduced to zero and the fan tries to restart every 5 seconds with a soft start by reverting to the IR function (see Fig. 1b). 1c. MS - Locked rotor protection (built in, no wire) The current is reduced to zero when the rotor is locked. To restart, turn the power OFF and ON again.

FG - Frequency Generator or Tachometer Output (Yellow Wire) This is an open collector output which provides a square wave signal if this open collector output is connected to a PULL UP resistor and is powered by the power supply voltage which is compatible with the input of the reading device (such as TTL input of a computer, etc). The maximum collector voltage may be up to 72VDC and the maximum collector current is 1mA. The power supply of the reading device must have the same ground potential as the fan (see Fig. 2, Fig 2a-1, and Fig 2a-2). The open collector output may also be protected internally by a 9K resistor from collector to ground (see Fig. 2).

9 AVAILABLE FEATURES. SG/PWM - Stop/Go Pulse Width Modulation (Blue Wire) This is an input function with the purpose of controlling the fan speed. The fan current is reduced to zero when the input signal is HIGH and the fan current is normal when the input signal is zero or if this input is left OPEN. This function is available as a simple SG function with ASYNCHRONOUS speed control applicable to frequency signals in the order to 2~Hz. The ASYNCHRONOUS input signal may be HIGH or LOW at the switching edges of the fan coil current.

OV - Over- Protection (Built-in, No wire) This function detects the power supply voltage and allows operation up to the rated maximum operating voltage. Typically, the maximum operating voltage (unless otherwise specified) is 2% over the specified rated voltage. If the power supply voltage increases over the 2% limit, the fan will stop running and the power supply current will be reduced essentially to zero. The maximum over-voltage protection range is twice the value of the rated voltage. For example, if the rated voltage is, the maximum voltage that can be applied accidentally is V. Likewise, for a V fan, the maximum applied over-voltage is (see Fig, 7a).

RPWM - Manual Variable Resistor Control (Orange Wire and White Wire) With this function, the speed can be controlled using an external variable resistor. This resistor may have any maximum value from 1K to 1K.

10 AVAILABLE FEATURES 6. CL - ( Limit under locked rotor is built- in - no wire) With this function, the current is limited during the restart (AS) period. (See Fig. 1b) 7a. FIXED CS (Constant is built in and is standard, no wire) This function allows the fan motor to operate safely over a very large power supply voltage range. For example, if the fan is designed to run at 42 RPM at the rated voltage of Volts, the fan motor will maintain the same RPM even when the supply varies from to 72 volts. The fixed CS function is preset internally and the maximum RPM is the rated RPM. (see Fig. 7a). 7b. PROGRAMMABLE CS with external components. (Orange + White Wires) This function can be implemented by the use of the RPWM function. For example, if the external resistor is made up of an 82K and an 18K resistor, then the center point of these resistors can be the input which will determine that 82% of the rated speed will be the maximum speed of the modified fan (of course If the resistor ends are reversed then 18% of the rated speed will be the new maximum speed). The resistor ends are tied to the ORANGE and BLACK wires and the center point is tied to the WHITE input wire. A very important use of this function is to overcome system impedance variations. The fan can be programmed to run at 2% lower of the rated speed at zero pressure. When the fan's static pressure is increased, the fan will be able to maintain the same speed under maximum pressure, thus becoming immune to system impedance variations.

This voltage input Vin may have any value from 1V to 2 V (standard value is 1 to 5V). The fan speed will vary linearly and is proportional to the % change of the Vin value, corresponding to the same % change of the maximum speed. The CS (constant speed), IR (Inrush Protection) and CL ( Limit) functions are included. The part # is followed by additional identification entry such as: VPWM C 5: This means that the fan speed will be 1 RPM (2%) at 2 V and 5 RPM (1%) at 1V. Furthermore, the fan will maintain the minimum speed if Vin < 2V and it will stop if Vin < 1.V (Mode C operation). The maximum fan speed is 5 RPM, and the stop point is typically set at 1% of maximum.

It is practical to have a single alarm (sound or light) that will indicate if any of the fans has stopped running. Pelonis Technologies can provide every fan with the RDb function in order to combine the multi-alarm function to a single alarm indicator. The diagram below shows the way to connect the multi-alarm. Any number of fans of any model equipped with the RDb function can be cascaded (maximum 1 fans). NOTES: Resistor R2 may be added if the application requires connecting to a voltage higher than 5V for the alarm signal.
