FND850-12RG Front-End Preliminary Data Sheet DC Input, 12V Output, 850 Watts Features RoHS compliant for all six substances Universal input voltage range (36-75 VDC) High power density, 15.15 Watts/cubic inch 1U or 2U height configurations Active current share with ORing FETs I2C interface status and control External standby voltage of 5 VDC @ 2 A Overtemperature, overload, and overvoltage protection Status LEDs: INPUT OK, DC OK, Overtemperature Airflow direction from rear-to-front Applications Telecom, datacom, and distributed power systems Description The FND850-12RG DC-DC front-end provides a 12 VDC output for telecom, datacom, and other distributed power applications. The FND850-12RG small 1U by 2U size allows for configurations of either height in hotswap redundant systems while its internal fan and cooling design permits wide use with reliable operation. Status is provided with front panel LEDs, logic signals, and via the I2C management interface bus. In addition, the I2C bus can enable the power supply, control fan speed, and adjust the output voltage from 7 to 12 VDC. This powerful feature allows the same power supply to be used in various applications. In addition, the FND850-12RG is designed with airflow from the rear of the power supply to the front. This airflow direction supports those critical applications where space limitations and/or higher ambient temperatures near the rear of the racking system, prohibit the discharge of higher temperature airflow from regular front-to-rear cooled power supplies. The FND850-12RG meets international safety requirements and is CE marked to the Low Voltage Directive (LVD).

Overtemperature/ Fan Failure Warning 12V output will shut down in the event of an overtemperature condition or blocked fan rotor. Supply's fan and Vaux are active. Power supply will recover when OT condition is removed. Amber OT LED will turn ON to indicate fault condition. OT/Fan Fail is an open-collector signal with 20-mA pull-down. High signal indicates a normal operating condition. Output will go low at least 100 ms before OT condition shuts down the power supply. An amber light will indicate FF DC OK TTL open-collector signal with active 20-mA pull-down. Represents percent of output voltage where signal is OK. Below this voltage, a signal high condition indicates an output which is out of tolerance. Green DC OK LED on front panel indicates normal operation. 1 90 Input Power Fail Warning TTL open-collector signal with active 20-mA pull-down. High indicates an input power fail. Power Fail Warning will turn OFF green INPUT OK LED.
