Information

The 200A DC Contactor manufacturer tells you that the DC contactor is used for long-distance access and disconnection of DC power circuit loads. In the control power circuit, the DC contactor is powered by the DC switching power supply to pull in the electromagnetic coil according to the working standard, and then control the posture of the main contact point. The 200A DC Contactor manufacturer tells you that the DC bottom voltage AC contactor is a DC excitation regulator used for long-distance frequent access and interruption of DC transmission lines and large space control power supplies with rated current up to 400V and rated voltage up to 630A. Electrical household appliances, which use vacuum pumps as magnetic blowing materials, have small size, high pressure resistance, strong breaking capacity, long service life, and circuit breaker-free maintenance, especially because their electric isolation will not leak out. This is a relatively rare The advantages.

The 200A DC Contactor manufacturer tells you that the key control goal of the DC bottom voltage AC contactor is the forward and reverse rotation, operation, termination and braking system of the DC motor. It can also be used to regularly connect and disconnect the lifting electromagnet, relay, Clutched magnet coils, etc., can also be used to control other power engineering loads, such as electric water heaters, lighting fixtures, DC welders, power capacitors, etc. The 200A DC Contactor manufacturer tells you that the DC contactor is equipped with a suitable actual operation organization, which can be installed as a high-voltage and low-voltage communication AC vacuum contactor and a high-voltage and low-voltage communication AC high-voltage circuit breaker magnetic blowing parts, used for power distribution equipment control, especially suitable It constitutes the explosion-proof power switch of the vacuum pump.
The 200A DC Contactor manufacturer tells you that a non-contact switch is a controllable power switch composed of electronic components. For example, the direct current SSR solid state relay is a way of non-contact switching devices. Compared with AC solid-state relays, DC solid-state relays have no zero control power supply circuit, and no need to set up a digestion and absorption power supply circuit. The 200A DC Contactor manufacturer tells you that the power switch can generally be composed of a single-phase electric thyristor or a high-power triode. Nowadays, the use of DC solid-state relays is becoming more and more common. One of the key reasons is that there is no fitness movement component when the DC solid-state relay is switched on and off, which is not easy to cause electrical isolation, and the DC contactor will not be damaged by mechanical equipment.
However, the DC solid state relays give the power supply circuit designer a lot of coordination in the control data signal input and the load working voltage level. The 200A DC Contactor manufacturer tells you that you must pay attention to it. When the DC solid state relay is used to control AC current, it is necessary to ensure that the induced electromotive force does not exceed the rated voltage of the DC solid state relay when the DC solid state relay is closed.
