product description :

DSTK220L32 is a  48V DC Contactor

Contactors are divided into AC contactors (voltage AC) and DC contactors (voltage DC), which are used in power, distribution and electricity. Contactor in a broad sense refers to the use of coil flow current to generate a magnetic field in industrial electricity, so that the contact is closed to achieve control of the load electrical appliances.

In electrical engineering, because the AC and DC main circuit can be quickly cut off and can be frequently switched on with large current control (up to 800 amps in some types) circuit devices, so often used in motor as a control object. It can also be used to control the power load of factory equipment, electric heaters, working machines and various power units. The contactor can not only switch on and off the circuit, but also has a low voltage release protection effect. Contactor control capacity is large, suitable for frequent operation and remote control. It is one of the important components in automatic control system.

Simply put, the working principle of the contactor is to control the on-off of the main contact connected to the main circuit by controlling the on-off of the auxiliary contact connected to the control circuit to achieve the requirements of the control circuit.

In industrial electricity, there are many models of contactors, and the current varies from 5A-1000A, which is quite useful.
