25 Basic Operation and Features Remote Sense (+SENSE, SENSE) Connect the +SENSE and SENSE pins of the module directly to the load to allow the module to compensate for the voltage drop across the conductors carrying the load current. If remote sensing is not required (for example if the load is close to the module) the sense pins should be connected directly to the module s output pins to ensure accurate regulation. Note: If the sense leads fail open circuit, the module will revert to local sense at the output pins. Incorrect connection of sense leads may damage the module. Remote Sense compensation at nominal V O only. Enable Control (ENABLE) The enable pin is a TTL compatible input used to turn the output of the module on or off. For models without suffix N, the output is enabled when the ENABLE pin open or driven to a logic high >2V, and disabled when the ENABLE pin is connected to SENSE or driven to a logic low of < 0.7V. For models with suffix N, the output is enabled when the ENABLE pin is connected to SENSE or driven to a logic low of < 0.7V, and disabled when the ENABLE pin is open or driven to a logic high > 2V. MODEL: AIH SERIES SHEET 25 OF 31

26 Basic Operation and Features (continued) Output Voltage Adjustment (V ADJ) The output voltage adjustment range is 80% to 120% for 12V, 15V, 24V output models, 74% to 120% for 5V model, 50% to 115% for 3.3V model and 50% to 110% for 1.8V output models respectively. The adjustment is made by using a resistor connected between VADJ and SENSE (+Vadj) or VADJ and +SENSE (Vadj).

27 Basic Operation and Features (continued) Clock Signals (CLK IN) The module s internal clock is accurate and stable over its full operating range and synchronization is not normally required, but it can reduce noise in paralleled systems. An external clock signal of 5V pkpk at 800 KHz ±5% can be connected to the CLK IN pins of AIH300V modules. If the clock input to any modules fails, the module will automatically switch back to its internal clock and will continues to operate normally. Current Share (CSHARE) To ensure that all modules in a parallel system accurately share current, the C SHARE pins on each module should be connected together. The voltage on the C SHARE pins represents the average load current per module. Each module compares this average with its own current and adjusts its output voltage to correct the error. In this way the module maintains accurate current sharing. Note: The SENSE and +SENSE pins of each module must also be connected together to ensure accurate current sharing. MODEL: AIH SERIES SHEET 27 OF 31

28 Basic Operation and Features (continued) Current Monitoring (C MON) The C MON pin provides an indication of the amount of current supplied by the module. The output of the C MON pin is a current source proportional to the output current of the module, where 0.2 to 1mA = 20 to 100% Iorated. The C MON output can be paralleled with C MON outputs from other modules to indicate the total current supplied in a paralleled system. Temperature Monitoring (TEMP MON) The TEMP MON pin provides an indication of the module s internal temperature. The voltage at the TEMP MON pin is proportional to the temperature of the module baseplate at 10mV per C, where: Module temperature ( C) = (Vtemp mon X 100) 273 The temperature monitor signal can be used by thermal management systems (e.g. to control a variable speed fan). It can also be used for overtemperature warning circuits and for thermal design verification of prototype power supplies and heatsink. MODEL: AIH SERIES SHEET 28 OF 31

29 Basic Operation and Features (continued) Over Current Protection (OCP) A constant current limiting circuit protects the module under overload or short circuit conditions. Module will operate back normally once the overload/fault is removed Overvoltage Protection (OVP) An independent overvoltage circuit monitors the module s output pins and will shut the module down in the event of an internal or external fault which causes the output voltage to rise above the preset limit. The module is reset by removing and reapplying the input power or toggle the ENABLE OFF/ON. Overtemperature Protection (OTP) If the module s baseplate temperature exceeds 110 C, the module will be shut down. The module is reset by baseplate temperature drop between 100 C and reapplying the input power or toggle the ENABLE OFF/ON I 2 C EEPROM Content Programming (SDA, SCL) This function is provided for product information storage, template as per customer define. Connect RS232 (Printer Port) from PC to Test unit at 300Vdc in and test with Read/Write capability of the I 2 C EEPROM. MODEL: AIH SERIES SHEET 29 OF 31
