The LE is a new ultra-high efficiency, open-frame, isolated DC/DC converter series
in an industry standard eight-brick footprint that provides up to 54 watts of output
power. The LE delivers very high output current at low voltages, and excellent
useable power density for todays high end applications. The first model in the
series features an input voltage range of 36 to 75VDC and is available with an
output voltage of 1.8V. The output voltage is adjustable from 90% to 110% of the
nominal value. The LE series also has a remote ON/OFF capability. Overcurrent
and overvoltage protection features are included as standard. With full
international safety approval pending including EN60950 (TÜV Rheinland) and
UL/cUL1950, the LE reduces compliance costs and time to market.
All specifications are typical at nominal input, full load at 25°C unless otherwise stated
