A solid state relay (SSR) is an electronic switching device that essentially works like a standard mechanical relay but without any moving parts. A conventional mechanical relay has contacts that may be opened or closed and an electromagnet to drive it. In an SSR, a semiconductor device is triggered by an input signal to switch an electrical load like a motor, a lamp, or a heater, on or off.The CPC1593GS is among the most popular, higher-performance and long-life compact solid state relay (SSR) designs available on the market. With a wide input voltage range of 9-30V DC and a maximum load current of 30A, it is a versatile SSR unit designed for various challenging applications, including over-current, over-temperature and over-voltage protection.

Application Field

The CPC1593GS is widely used in modern industrial automation, home appliances, heaters, and other external control systems. The CPC1593GS is designed to control high power loads with a maximum output current of 30A. It can be used in machines, illumination, radiators, fan heaters, conveyor belt systems, residential lighting, thermostats, home automation, and more. With its higher-performance and long-life, it is a versatile unit designed for various challenging applications.

Working Principle

The CPC1593GS SSR switch consists of an opto-isolator, a Triac circuit, an over-temperature protection circuit, an over-voltage protection circuit, and an over-current protection circuit. When an AC signal is applied to the input of the SSR, the Triac circuit works through the opto-isolator. This causes the Triac to trigger an open circuit, which will cause the external load to be energized and the conduction path to be connected.

When the input voltage rises, the Triac is instantaneously triggered and the load starts to be energized. The over-temperature protection circuit triggers the SSR to shutoff should the temperature around the SSR exceed the maximum temperature threshold. The over-voltage protection helps to protect the SSR from electrical spikes that occur on the AC power line. The over-current protection shuts off the load if it exceeds the stated operating current.

The CPC1593GS is a well-designed solid state relay that offers high performance and long-life for a wide range of applications. Its built-in protection circuits help to maintain the SSR in optimal condition, while its flexible control capabilities make it an ideal choice for any industrial or home automation application. With its high current-carrying capacity, it offers a cost-effective way to switch high power loads.
