APPLICATIONS
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.
