Relay is an automatic switching component with isolation feature. It is widely used in remote control, telemetry, communication, automatic control, mechatronics and power electronic equipment. It is one of the most important control components.

I. General power relay has versatility and outstanding features

I). Basic feature: suction voltage and release voltage. Under no-load conditions, the general-purpose relays should have the operating voltage and release voltage in accordance with the standard, rated voltage, five-suction operating voltage, and five-release voltage.

II). Withstand voltage feature: the connection between the non-conductive parts and the conductive parts of the cabinet should be able to withstand 50Hz, 550V 1min sinusoidal voltage test, the insulation does not break down. When we need mass and continuous production, we can use the test with a voltage of 660V for 1 second instead.

III). Temperature resistance: The general relay can work according to your requirements without being restricted by the lower working temperature.

IV). Temperature and humidity cycle feature: according to the provisions of the temperature and humidity cycle feature test, return to the room temperature after the test, the voltage drop of the relay contact should be specified.

V). Vibration feature: when the relay is not working, the requirements for "other parts" in the installation site should be subjected to the X and three-direction sweep frequency vibration test.

VI). Salt spray resistance: when the general relay is not working, the general requirements of the salt spray test after 48h are that the general relay exhibits absorption dynamics.

II. General relay has wide applications

I) Expand the control range:for example, when the control signal of a multi-contact relay reaches a certain value, it can change, break, and connect multiple circuits at the same time according to different forms of contact groups.

II) Zoom in: for example, sensitive relays, intermediate relays, etc., can control very large power circuits with a very small amount of control.

III) Comprehensive signal: when multiple control signals are input to a multi-winding relay in a prescribed form, after a comparative synthesis, a predetermined control effect is achieved.

IV) Automatic, remote control and monitoring: for example, the relay on the automatic device together with other electrical appliances can form a program control circuit, so as to realize automatic operation.

We have been focusing on the development and production of relays for many years, we supply various type relay, provide 12V 80A/40A relay for automotive, high power relays, general electromagnetic relays, magnetic hold relays, automotive wiring harness, relay socket, etc.
