Cross Regulation³
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.

EMI Filter
Input filter components (C1, C3, L) are used to help meet conducted emissions requirement. These components should be
mounted as close as possible to the module; all leads should be minimized to decrease radiated noise.

1 = Measured Input reflected ripple current with a simulated source inductance of 12uH.
2 = Tested by minimal Vin and constant resistive load.
3 = Dual: One load is 25% to 100% load, the other load is 100% load, the output voltage variable rate is within ±5%.
4 = Tested by nominal Vin and 25% load step change (75% - 50% - 25% of Io)
5 = The WRA-ZMD-30W&WRB-ZMD-30W series can meet EN55022 Class A With an external filter in parallel with the input pins.
6 = An external filter capacitor is required if the module has to meet EN61000-4-4 and EN61000-4-5
7 = The remote on/off control pin is referenced to –Vin (Pin2).
