DC-DC step Up or Down Converter

The power supply adopts pulse width modulation (PWM) method, with no the isolation switch. It has high conversion efficiency, stable performance and perfect protection function. The characteristics is light weight, it is widely used in automobiles, LED, industrial and other fields.

AC/DC power adapter built-in EMI filter, good electromagnetic compatibility, high efficiency, it has over voltage protection, over current protection, over load protection.
Power adapter is mainly used for electronic alarm series, security monitoring system, anti-theft alarm system, electronic door locks and attendance machine, the language repeater, keyboard, speakers, massage equipment, etc.
Products comply with the latest Europe energy efficiency standards, specially provide power for your products.
This product is apply for the BOOST the isolation switch regulated voltage power supply, the rated input voltage can be is 12 vdc /24vdc/36vdc/48vdc, also output voltage is can be 12 vdc /24vdc/36vdc/48vdc
