Solid State Relays (SSRs) are components used for controlling many different kinds of electrical loads, and the CKRA4820E is no exception. Also known as solid state contactors, these control devices use semiconductor technology in lieu of traditional electro-mechanical switching, and provide a longer life, more reliable operation with faster response time. The CKRA4820E solid state relay provides a wide range of features and benefits to meet users\'s needs, and it is an ideal solution for industrial, commercial, and residential environments.

The CKRA4820E is a zero-crossover solid state relay with exceptionally small physical package. This compact design offers improved performance in a variety of applications, such as low current and high-current switching, constant voltage applications, and temperature control. It is also equipped with a current-carrying capacity of up to 15 Amps, enabling it to be used for more demanding applications. Furthermore, the device has an insulation resistance of up to 10,000 V, and provides an extremely fast response time.

The main features of the CKRA4820E are its high current-carrying capacity, wide input voltage range (90-265VAC), high temperature operation (up to 110 °C), and fast response time. It is also UL recognized and RoHS compliant, and provides reliable and efficient use. In addition, the device features surge immunity, switch signal indication, and a built in diode with an insulation voltage of 5kV, making it suitable for many applications, such as motor control, solenoid valves, process control, lighting control, and others.

The working principle of the CKRA4820E is based on the basic principles of semiconductor switching. It uses a pair of bi-directional MOSFETs to achieve a solid state connection between the input and output terminals. When the input voltage is above the ON level (Von min), the relay is activated and the load is connected to the input voltage. When the input voltage is below the OFF level (Voff max), the relay disengages and the load is disconnected from the input voltage.

The CKRA4820E solid state relay is a versatile device that can be used for a wide variety of applications. It is ideal for use in heavy-duty industrial, commercial, and residential applications due to its features, such as its high current-carrying capacity, wide input voltage range, high temperature operation, and fast response time. Additionally, its UL recognition and RoHS compliance ensure safe and reliable use for many different applications.
