The WRA-ZMD-30W&WRB-ZMD-30W series
is a family of cost effective 30W, single and
dual output DC-DC converters with an ultra wide
input range of 4:1. These converters are
encapsulated in nickel coated brass 2"x1"
case with high performance features:1500VDC
input/output isolation voltage,continuous short
circuit protection with automatic restart and tight
line/load regulation,over current protection, over
voltage protection, over temperature protection,
high efficiency operation and soft start.
