The FND300-1012G is a highly-efficient bus converter with one high current output, which can be used in a wide range of applications. Passive current share along with internal ORing diodes allow this unit to be also used in redundant, hot-swap applications. The FND300 meets international safety standards and displays the CE Mark for the Low Voltage Directive. RoHS compliant for all six substances 40.5 to 72 VDC Input Range 12 V output Telecommunication Equipment 2000 VAC I/O electric strength test Highly-efficient topology High-density design 4 x 1.65 x 8.5 cassette 2 I C interface Supervisory signaling Overtemperature, output overvoltage, and output overcurrent protection ORing diode included for true redundant operation Safety approvals: UL60950-1/ CSA 60950-1, & TUV EN60950-1 North America +1-866.513.2839 Asia-Pacific +86.755.29885888 Europe, Middle East +353 61 225 977 tech.support psbel.com 2015 Bel Power Solutions, Inc.
