High Power Relay

GH Subminiature High Power Relay

A High Power Relay is an electronic component used to control or switch high power circuits. It is commonly used as a switch to control a large current through a small current. The power relay is composed of a control circuit and a load circuit. Through the signal of the control circuit, the power switch in the load circuit can be turned on or off.

Power relays are widely used in various electrical equipment, such as lighting systems, air conditioning systems, and motor drive systems. Compared with other relays, power relays have higher current and voltage capacity and can withstand larger loads. At the same time, power relays also have the characteristics of high reliability, long life and low noise, making them an indispensable part of modern automation systems.
