48 volt to 12 volt DC/DC Converter (Regulator)
Fully isolated 150 Watt 48 volt to 12 volt DC-DC converter at low cost. Suitable for voltage stabilization of automobile electronics, special purpose UPS, etc.
This fully isolated DC/DC converter is useful for voltage conversion to operate 12 volt electronics off 48 volt vehicles, golf carts, fork lifts and telecom busses, best for radios, stereos, DVDs, CB radios, transmitters. This DC to DC converter closely regulates the output voltage over a range of input voltages.
“Fully Isolated” means that you can ground either the positive or negative on both the input and the output for complete polarity flexibility.
