　 Description
　

The EF2000 Super brick DC/DC converters is a high density, high reliability 

power converter. They are targeted specifically at the aerospace, aerocraft,
portable weaponry industry and distributed power markets. With an input
voltage range of 56 -90V and 88-132V，they are available with an output 
voltage of 110 and 28 Volts. The module feature an input filter, input undervoltage 
lockout, output overvoltage and and short circuit protection. overtemperature 
protection, output current limiting  The fully enclosed, encapsulated construction 
with aluminum heat spreader design achieves efficient heat transfer with no 
hot spots. The use of Patent- pending Hybrid Planar Transformer technology 
and other patent-pending design concepts facilitate maximum power delivery 
with the highest efficiency of up to 97%. The unique enclosed construction with 　
aluminum heat spreader design achieves efficient heat transfer with no hot spots.
