The FNP600/850/1000 power factor corrected (PFC) front ends provide (depending on model) either a 12 VDC or a 48 VDC output for telecom, datacom, and other distributed power applications. Their small 1U by 2U size allows for configurations of either height in hot-swap redundant systems while their 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 on the 12 VDC models it allows for adjusting the output voltage from 7 to 12 VDC. This powerful feature allows the same power supply to be used in various applications where bus voltages driving isolated dc-dc converters and POL regulators may be different. Also, the FNP850-12R is uniquely 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 rack system, prohibit the discharge of higher temperature airflow from regular front-to-rear cooled power supplies. The FNP600/850/1000's meet international safety requirements and are CE marked to the Low Voltage Directive (LVD).
