Switching Power Supply

 

Switching DC power supplies were first introduced in the late 1970's, today they are the most popular form of DC power supplies in the market due to their exceptional power effiency and great overal performance. A Switching DC power supply (also known as switch mode power supply) regulates the output voltage through a process called pulse width modulation (PWM). The PWM process generates some high frequency noise, but enables the switching power supplies to be built with very high power effiency and small form factor. With a good design, a switching power supply can have excellent load and line regulation.

 

With over 30 years of design and manufacturing knowledge, Voteq regulated switching power supplies have set a new standard in flexibility, reliability and cost-effectiveness. Our variable switching DC power supplies have built-in over-voltage and reverse-voltage protection, and have been widely used industrial and labotory applications, including manufacturing, product design verification, lithium battery charging, anodizing, LED applications, electroplating (use as plating rectifiers), electrolysis, hydrogen generation applications, etc.

 

Typical applications for switching DC power supplies include:
