Contactor (Solid State) is an electrical device used to switch off or on an electrical circuit remotely and locally. The device is typically used in industrial fields for the control of heat, air conditioning, water supply, mass production systems, motion control, and many other applications. The contactor (solid state) is also used to control switching in a number of other applications.

HDC200A120 is one of the contactor (solid state) models to help achieve electrical heating equipments such as fan coil unit, electric towel radiator, convector, etc. in commercial and industrial application.

The HDC200A120 contactor (solid state) is a two-pole device with a rated current ranging from 16A to 30A (with coil voltage of 24-353VAC/12-167VDC). Its contact sealing surface is silver-nickel alloy, and it is highly integrated with a few terminal screws for convenient connection. It has a compact structure and is shockproof, water-proof and corrosion resistant, which makes it a reliable choice even in a harsh environment. The contactor (solid state) can achieve manual/automatic switch, overload and short circuit protection and other functions.

The working principle of the HDC200A120 contactor (solid state) is to rely on power to trigger a switch mechanism such as temperature, pressure, frequency, etc. The power supply will be transmitted to the solid state components in the contactor (solid state) which electro-magnetically vibrate and generate self-oscillation. The oscillator will then drive the current strength controlled by the circuit design to pass through the main contactor, thereby turning on or off the power. The contactor (solid state) also keeps the power control system continuously running under some fuzzy conditions.

The HDC200A120 contactor (solid state) can be used in extremely harsh environment such as high temperature, high pressure, starting performance and overload protection. It is also used in advanced automation systems, safety and protection systems and emergency systems, which require reliability and consistency of the contactor (solid state). Besides, due to its smaller volume (in comparison to the alternatives) and higher efficiency, the utilization of this kind of contactor (solid state) is increasing.

In summary, the HDC200A120 contactor (solid state) is designed to provide safe and reliable handling of high-power mechanisms and electrical equipment in commercial and industrial applications. Its high efficiency, stability and reliability have made it one of the most popular contactor (solid state) products in the market. Thus, it has become an integral part of electrical heating equipment, advanced automation systems, safeties and emergency systems.
