3 1 Function 1.1 Input voltage range Input voltage range of the power supplies is from AC5V to AC264V (please see SPECIFICATIONS for details). In cases that conform with safety standard, input voltage range is AC-AC24V (5/6Hz). If input value doesn t fall within above range, a unit may not operate in accordance with specifi cations and/or start hunting or fail. If you need to apply a square waveform input voltage, which is commonly used in UPS and inverters, please contact us. When the input voltage changes suddenly, the output voltage accuracy might exceed the specifi cation. Please contact us. 1F, 15F, 3F A power factor improvement circuit (active fi lter) is not built-in. If you use multiple units for a single system, standards for input harmonic current may not be satisfi ed. Please contact us for details. 1F, 15F, 3F, 5F, 75F, F, 15F, 24F, 3F Operation stop voltage is set at a lower value than that of a standard version (derating is needed). -Use Conditions Output ( ) 3.3V 1F 5W (3W) 15F 7.5W (5W) 3F 1W (7.5W) 5F 15W (1W) 75F 25W (15W) F 3W (2W) 15F 5W (3W) 24F W 3F W (75W) Input AC5V or DC7V Duty 1s/3s * Please avoid using continuously for more than 1 second under above conditions. Doing so may cause a failure. 1.2 Inrush current limiting An inrush current limiting circuit is built-in. If you need to use a switch on the input side, please select one that can withstand an input inrush current. 24F, 3F Thyristor technique is used in the inrush current limiting circuit. When you turn power ON/OFF repeatedly within a short period of time, please have enough intervals so that the inrush current limiting circuit becomes operative. When the switch of the input is turned on, the primary inrush current and secondary inrush current will be generated because the thyristor technique is used for the inrush current limiting circuit. 1.3 Overcurrent protection An overcurrent protection circuit is built-in and activated at 15% of the rated current or 11% of the peak current. A unit automatically recovers when a fault condition is removed. Please do not use a unit in short circuit and/or under an overcurrent condition. Intermittent Operation Mode Intermittent operation for overcurrent protection is included in a part of series. When the overcurrent protection circuit is activated and the output voltage drops to a certain extent, the output becomes intermittent so that the average current will also decrease. 1.4 Overvoltage protection An overvoltage protection circuit is built-in. If the overvoltage protection circuit is activated, shut down the input voltage, wait more than 3 minutes and turn on the AC input again to recover the output voltage. Recovery time varies depending on such factors as input voltage value at the time of the operation. In option -R2, overvoltage protection is removed by toggling ON/ OFF signal of remote control. Remarks : Please avoid applying a voltage exceeding the rated voltage to an output terminal. Doing so may cause a power supply to malfunction or fail. If you cannot avoid doing so, for example, if you need to operate a motor, etc., please install an external diode on the output terminal to protect the unit. 1.5 Output voltage adjustment range Adjustment of output voltage is possible by using potentiometer. Please refer to instruction manual 5.1. Option -Y is recommended which can adjust the output voltage. 1F Resistance for line fi lter is used for inrush current limiting. 15F, 3F, 5F, 75F, F, 15F Thermistor is used in the inrush current limiting circuit. When you turn the power ON/OFF repeatedly within a short period of time, please have enough intervals so that a power supply cools down before being turned on. E-24

4 1.6 Output ripple and ripple noise Output ripple noise may be infl uenced by measurement environment, measuring method fi g.1.1 is recommended. 1.7 Isolation Osiloscope/ Ripple noise meter Bw:2MHz For a receiving inspection, such as Hi-Pot test, gradually increase (decrease) the voltage for the start (shut down). Avoid using Hi- Pot tester with the timer because it may generate voltage a few times higher than the applied voltage, at ON/OFF of a timer. 1. Reducing standby power 1F, 15F +Vout -Vout A circuit reducing standby power is built in 1F and 15F. (standby power :.5W typ) The load factor: Io=-35%, the internal switch element is intermittent operated, and the switching loss is decreased. The specifi cation of the Ripple/Ripple Noise changes by this intermittent operation. The value of the ripple/ripple Noise when intermittent operates changes in the input voltage and the output current. Please contact us for details. F, 15F, 24F, 3F As for option -R2, reducing standby power is possible by OFF signal of the remote control. Please refer to instruction manual 5.1.

5 2.2 Parallel Operation Parallel operation is not possible. Redundancy operation is available by wiring as shown below. Power Supply Power Supply + - Even a slight difference in output voltage can affect the balance between the values of I1 and I2. Please make sure that the value of I3 does not exceed the rated current of a power supply. I3 [ the rated current value 3 Assembling and Installation 3.1 Installation method + - I1 I2 This power supply is manufactured by SMD technology. The stress to P.C.B like twisting or bending causes the defect of the unit,so handle the unit with care. In case of metal chassis, keep the distance between d1 & d2 for to insulate between lead of component and metal chassis, use the spacer of mm or more between d1. If it is less than d1 & d2, insert the insulation sheet between power supply and metal chassis. I3 Load Fig.2.4 Example of redundancy operation There is a possibility that it is not possible to cool enough when the power supply is used by the sealing up space as showing in Figure 3.2. Please use it after confi rming the temperature of point A and point B of 3.2. Case Power supply Fig.3.2 Installation example 3.2 Derating Environment to use it and Installation environment When using it,it is necessary to radiate heat by the heat of the power supply.

Vcc-(1.1+RiX.5) R[W]=.5 * Please wire carefully. If you wire wrongly, the internal components of a unit may be damaged. Remote ON/OFF circuits (RC+ and RC-) are isolated from input, output and FG. -R2 (F, 15F, 24F, 3F) -The usege is the same as option -R, please refer to Option -R. -Reducing standby power is possible by OFF signal of the remote control. -Start up time by ON signal in remote control is 35ms(typ). -The latch condition in overvoltage protection is removed by toggling ON/OFF signal of remote control. -Standby power F,15F,24F.2Wtyp (ACV),.7Wtyp (AC2V) 3F.25Wtyp (ACV), 1.1Wtyp (AC2V) f5.5max -T1 (3F) -Option -T units have horizontally positioned screws on a terminal block. -Please contact us for details about appearance. FG AC (N) AC (L) 5.2 Others Fig.5.4 lifting method Fig.5.5 Example of option -T1 terminal block This power supply is the rugged PCB type. Do not drop conductive objects in the power supply. At light load, there remains high voltage inside the power supply for a few minutes after power OFF. So, at maintenance, take care about electric shock. This power supply is manufactured by SMD technology. The stress to PCB like twisting or bending causes the defect of the unit, so handle the unit with care. -Tighten all the screws in the screw hole. -Install it so that PCB may become parallel to the clamp face. -Avoid the impact such as drops. -V +V E-34

14 While turning on the electricity, and for a while after turning off, please don t touch the inside of a power supply because there are some hot parts in that. When a mass capacitor is connected with the output terminal (load side), the output might become the stop or an unstable operation. Please contact us for details when you connect the capacitor. 1F, 15F When these power supplies are connected to the input terminal in parallel, the total capacitance between line and line becomes big. Therefore, the electrical discharge resistance on the safety standard might become necessary. Please contact us for details when safety standard is necessary at multiple units usage. E-35
