APPLICATIONS
The WRA(B)-YQD-40W Series of DC/DC
converters has been designed for a wide range of
applications including communications, industrial
systems and battery powered mobile equipments.
Key features are high power density and 2:1 wide
input ranges of 18~36 VDC and 36~72 VDC.(But
also can do high power density and 4:1 ultrawide
input ranges of 9~36 VDC and 18~72 VDC.)
PROTECTION
Above 105% rated output power
Protection type : Over power limiting, recovers automatically after fault
condition is removed
XX03 :3.8~4.95V
Over Voltage
XX12:13.8 ~ 18V
XX05 :5.75 ~ 7.5V
XX15:17.25 ~ 22.5V

NOTE
1. All parameters are specified at normal input, rated load, 2570% RH ambient.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted
pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
3.Line regulation is measured from low line to high line at rated load.
4.Load regulation is measured from 10% to 100%rated load
5. Please prevent the converter from operating in overload or short circuit condition for
more than 30 seconds.
