## VEC40 Series 

## 40W 

## **AC-DC POWER SUPPLIES** 

The VEC40 Series of desktop AC-DC power supplies deliver 40W offering single output voltages of 12V, 15V and 24V, and are designed for high volume applications. A low standby power which is less than 75mW enables VEC40 to comply with energy efficiency level VI standards. 

With world-wide safety approvals, class B compliance for conducted and radiated emissions, high efficiency and 3kVAC isolation, the limited power source (LPS) approved VEC40 series benefits system designers with easy integration into a wide range of industrial applications including test and measurement, process control, industrial displays and analytical instrumentation. 

## **Features** .
