•

Available RoHS compliant

These are new high e ciency, open-frame, isolated 40 A converters in an industry standard dual

quarter-brick footprint. These converters deliver high output current at low voltages, and excel-

lent useable power density for today’s high end applications. This series features an input volt-

age range of 36 Vdc to 75 Vdc and output voltages of 1.2 V/3.3 V, 1.5 V/3.3 V, 1.8 V/3.3 V 2.5

V/3.3 V, and 5 V/3.3 V. The output voltage on each model is adjustable from 90% to 110% of

the nominal value. Typical e ciencies are 90%. This series also has a remote ON/OFF capabili-

ty. Over-current and over-voltage protection features are included as standard. Designed to

meet inter national safety agency approvals, including EN60950-1 and UL/cUL60950, this series

reduces compliance costs and time to market.
