ALZ21B05W

Power Relays, Over 2 Amps

The ALZ21B05W power relay offers a wide range of applications, mainly used in the fields of automation, IT, communications, medical and industrial control. It can work in both AC and DC circuits and its operating voltage range is 0 to 250VAC/5A or 0 to 125VDC/3A. It is also capable of working at temperatures from -40°C to 85°C.

Working Principle

The ALZ21B05W power relay has a double-earthed switch, which uses two electromagnets to open and close the contacts. To open the contacts, the current flow through the switch must be reduced and an opposite voltage must be applied. To close the contacts, an electric current must be induced into the relay, which will activate the electromagnets and close the contacts. The switching speed of this relay is impressive, with a rated control interval of 0.01ms. It is also capable of handling high inrush currents up to 5A.

Applications

The ALZ21B05W power relay is mainly used in automation and industrial control. It can be used to control a wide range of equipment, such as pumps, fans, or motors. It is also used in medical equipment, as it offers precise control and high durability. In addition, it is used in telecommunications, IT, and other applications where high speed and precise control is needed. It can also be used in car or truck engines, as it offers high-temperature resistance.
