The power supply adopts high frequency switching power technology. It is controlled by high performance microcomputer. The power supply is widely used in industrial control systems and electronic product burn-in and testing applications. It is suitable for all kinds resistive load, capacitive load, inductive load. The control chip of the DC voltage stabilized power supply adopts the mature imported components at present and the power components adopt the latest developed great power in the world. Compared with traditional linear power supplies, the high -frequency switching design significantly reduces size and weight. Compared with the traditional power supply, the high frequency DC power supply has the advantages of small size, light weight and high efficiency. At the same time, it creates the conditions for reducing the volume of high-power DC power supply, which is also called high frequency switching power supply. DC regulated power supply has completed protection function.
