Solid state relays are devices that electronically control the switching of electrical loads using a solid state circuit. The CC4850D2VR solid state relay (SSR) is a two-channel, 100A, 250VDC/800VAC rated device with integrated LED indication. It offers excellent performance and reliability with minimal board space. It has a wide range of application fields, including industrial automation, machine tools, welding, motors, home appliances, and lighting control. This article will explain the working principles of the CC4850D2VR SSR and its application fields.

CC4850D2VR Working Principle

The CC4850D2VR is a hybrid switching device that combines a high power silicon-controlled rectifier (SCR) and an LED to control an electrical load. The SCR is responsible for driving the load, while the LED acts as a control interface. When the control voltage is applied to the LED, an optical signal is emitted, which is then received by the SCR and used to switch the load. In terms of safety, the LED-SCR combination ensures that the high current of the load is safely switched on/off without electrical arcing or mechanical vibration.

The CC4850D2VR SSR operates by means of zero crossing, which means that the switching is done when the input voltage is at zero, thus minimizing the stress to the device. It also utilizes a zero-voltage turn on feature that enables faster and more accurate switching of the load. Additionally, its high sensitivity to voltage fluctuations allows it to detect and respond to changes in input voltage, ensuring optimal performance. The integrated LED indication provides the user with a visual indication of the status of the load.
