Introduction to Solid State Relays

Solid state relays are relays that use electronic components and semiconductors to control an electrical connection without using any moving parts. They use feedback signals from two or more inputs to provide a contactless control between an output and an input source. Solid state relays are replaces traditional electromechanical relays in being more cost effective and efficient.

CD2450W2VH Solid State Relay

The CD2450W2VH is a type of solid state relay which is compact, features high tunneling speed and current transmission functions. It is capable of providing an effective connection between sources while improving the signal and current quality, eliminating unnecessary losses.The CD2450W2VH is manufactured by Semikron – a leading manufacturer of semi conductor and power components. The device also features a low input leakage current of 1µA and high performance up to 660V, serving as the perfect solution for applications including lighting, telecommunications, switchgear, control systems and embedded control systems.

CD2450W2VH Application Field and Working Principle

The CD2450W2VH has various application fields, including lighting, telecom, drives, motor speed control, temperature or pressure control, sound systems and more. It is a highly versatile component which is suited for a wide range of applications.The working principle behind the CD2450W2VH is simple. The device consists of two different internal components, an opto-isolator and a power semiconductor. The opto-isolator contains a light-emitting diode (LED) and a photosensor which can detect the presence of light from the LED. The power semiconductor acts as the switch component, triggering the connection between the input and the output. When connected to a source of power, the opto-isolator will light up the LED and the photosensor will detect the light, sending a signal to the power semiconductor. The power semiconductor then triggers the connection between the input and the output source. When the input and output are connected, the current will then flow between them.

Conclusion

The CD2450W2VH is a type of solid state relay which offers innovative functions, including high tunneling speed and current transmission. It is a versatile component which is suitable for applications including lighting, telecommunications, switchgear, control systems and embedded control systems. The device feature a low input leakage current of 1µA and high performance up to 660V, making it an ideal solution for a variety of applications.
