This is a new high efficiency, open-frame, low profile, single board, isolated DC/DC
converter series in an industry standard eight-brick footprint that provides up to 100W of
output power. The series delivers very high output current at low voltages, and excellent
useable power for today’s high performance applications. The series features an input
voltage range of 36 to 75VDC and is available with output voltages of 1.2V, 1.5V 1.8V, 2.5V,
3.3V and 5.0V. The output voltage is adjustable from 80% to 110% of the nominal value. The
series also has a remote ON/OFF capability. Over-current, over-voltage and over-temperature
protection features are included as standard. Full international safety approval including
EN60950 VDE and UL/cUL60950, reduces compliance costs and time to market.
