Description  
The FND850-12DRG DC-DC front-end provides a 12 VDC output for telecom, datacom, and other distributed  
power applications. The FND850-12DRG small 1U by 2U size allows for configurations of either height in hot-  
swap 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 FND850-12DRG 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 FND850-12DRG meets international safety requirements and is CE marked to the Low Voltage Directive  
(LVD).
