The PFC500 products of the PerFormanCe Power Series combine high 3 performance midrange power with high power density (4.4 watts/in ) and high reliability to meet the requirements of communications, commercial, and industrial systems. Providing tightly regulated DC power, the PFC500 delivers full output performance with only 300 Linear Feet per Minute (LFM) forced-air cooling (factory-installed fan optional). Main channel current sharing is provided for redundant applications. Units are available with SAE mountings or optional metric mountings. The PFC500 product line is approved to the latest international regulatory standards, and displays the CE Mark. RoHS Compliant Power Factor Correction meets EN61000-3-2 (AC input versions) Fully-regulated outputs Remote sense Logic level Inhibit Current Share, Power Fail, and Power Good Signals Overtemperature, overvoltage, and overcurrent protected Available with metric or SAE mountings Input transient & ESD compliance to EN61000-4-2/-3/-4/-5 Fan output voltage and optional fan Optional isolation diodes for parallel or redundant operation DC input versions (36-75 VDC) Asia-Pacific Europe, Middle East North America +86 755 298 85888 +353 61 225 977 +1 866 513 2839 2015 Bel Power Solutions, Inc.
