This is a new high efficiency, open-frame, low profile, single board, isolated dc-dc converter
series in an industry standard quarter-brick package that provides up to 200 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 two input voltage ranges 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 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
