APPLICATIONS
6mA
The WRA(B)-YD-12W series offer 12 watts of output
power From a package in an IC compatible 24pin DIP
configuration.WRA(B)-YD-12W series have 2:1 wide
input voltage of 9-18,18-36 and 36-72VDC.
The WRA(B)-YD-12W have features 1500VDC of
isolation,short circuit protection and as well as five sided
shielding.
NOTE(Apply to this data):
1.MIL-HDBK-217F Notice2 @Ta=25℃,Full load(ground,Benign,controlled environment).
2.Typical value at nominal input voltage and no load.
3.Typical value at nominal input voltage and full load.
4.The ON/OFF control pin voltage is referenced to -INPUT.
5.The WRA(B)-YD-12W series can meet EN55022 Class a with parallel an external capacitor to the input
pins. Recommend: 12Vin:6.8µF/50V. 24Vin:4.7µF/50. 48Vin:2.2µF/100V.
6.An external input filter capacitor is required if the module has to meet EN61000-4-4,EN61000-4-5.
The filter capacitor Power Mate suggest:Nippon chemi-con KY series,220/100V,ESR 48MΩ.
