Dpstar Group is a Malaysia power supply system supplier specializing in AC/DC power supply and switching mode power supply systems. The JSF series switching mode power supplies provide efficient power conversion and stable power supply with minimal noise and ripple.

A switched-mode power supply (SMPS) is an electronic circuit that converts power using switching devices that are turned on and off at high frequencies, and storage components such as inductors or capacitors to supply power when the switching device is in its non-conduction state. Switching power supplies have high efficiency and are widely used in a variety of electronic equipment, including computers and other sensitive equipment requiring stable and efficient power supply. A switched-mode power supply is also known as a switch-mode power supply or switching-mode power supply.
