Datasheet
**Additional Resources: Product Page Technical Documentation** Power Shelves 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 hotswap 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 I[2] C management interface bus. In addition, the I[2] C 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. - RoHS lead free solder and lead solder exempted products are available 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. - High density front-ends 10.5 to 16.1 W/in[3] - Universal input voltage range (90-264 VAC) with PFC - 1U or 2U height configurations - Droop current share with ORing FETs - I[2] C interface status and control The FNP600/850/1000's meet international safety requirements and are CE marked to the Low Voltage Directive (LVD). - Standby voltage of 12 VDC @ 0.5 A - Overtemperature, overload, and overvoltage protection - Status LEDs: AC OK, DC OK, Overtemperature - FNP850-12 model has airflow direction from front-to-rear or from rear-to-front (-12R model) - Telecom - Datacom - Distributed Power Systems - ON/OFF Enable switch - shuts OFF Vo1; Vaux and fan are operational. **North America** +1-866.513.2839 **Asia-Pacific** +86.755.29885888 **Europe, Middle East** +353 61 225 977 tech.support@psbel.com belpowersolutions.com © 2015 Bel Power Solutions, Inc.

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 540,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
