100 V, 100 ms input voltage transient rated
Available RoHS compliant
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 100 W 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 18 Vdc to 36 Vdc and 36 Vdc to 75 Vdc and is available with output voltages of
1.2 V, 1.5 V 1.8 V, 2.5 V, 3.3 V and 5.0 V. The output voltage is adjustable from 80% to 110% of
the nominal value. The series also has a remote ON/OFF capability. Overcurrent, overvoltage and
overtemperature protection features are included as standard. Full international safety approval
including EN60950-1 VDE and UL/cUL60950, reduces compliance costs and time to market.
All specifications are typical at nominal input, full load at 25 °C ambient unless otherwise stated
