If the over current condition persists beyond a few milliseconds, the module will shut down into hiccup mode and restart once every 400mS. The module operates normally when the output current goes into specified range. The typical average output current is 5A during hiccup. output current waveform Expansion of on time portion Bel Fuse Inc. 206 Van Vorst Street, Jersey City, NJ 07302 • Tel 201-432-0463 • Fax 201-432-9542 • www.belfuse.com 7 ISOLATED DC/DC CONVERTERS 36 Vdc - 75 Vdc Input 6.5 Vdc /60 A Output, 1/4 Brick Bel Power Inc., a subsidiary of Bel Fuse Inc. Aug. 09, 2010 Over Voltage Protection The output overvoltage protection consists of circuitry that monitors the voltage on the output terminals. If the voltage on the output terminals exceeds the over voltage protection threshold the module will shutdown into latch off mode. The overvoltage latch can be reset by either cycling the input power or toggling the on/off signal for one second at least.
