1 Overview

        The switching power supply produced by our company is designed with the most advanced PWM technology and 

stable circuit topology in the world. It is a power supply product with strong practicability, high reliability and high cost 

performance. The whole machine has the characteristics of high efficiency, wide operating temperature range, strong 

anti-interference ability, good electromagnetic compatibility, strong adaptability of power grid, fast dynamic response, 

high stability, small noise ripple and strong protection function. It has multiple protection functions such as short circuit, 

overload and over voltage. Our company has AC/DC, DC/DC two kinds of various types of switching power supply, and 

can choose the switching power supply of the required power.

        This product is widely used in industrial automation control, military equipment, scientific research equipment, 

industrial control equipment, communication equipment, power equipment, instrumentation, medical equipment, 

semiconductor refrigeration and heating.
