Solid state relays, also known as solid state contactors, are electromagnetic switching devices that control the flow of electric current from one circuit to another. These relays use solid state switches, such as transistors and diodes, to make or break the connection between the two circuits. The CKRD4810 is a solid state relay designed specifically for industrial applications.

Application Field

The CKRD4810 is an industrial-grade solid state relay with a rating of up to 48V AC/DC at 10A and designed to switch high voltage loads. It is recommended for controlling AC or DC motors, conveyor belts, computer driven equipment, HVAC systems, production process machines, and other industrial systems. It’s ideal for applications requiring low switching noise, high efficiency, and high reliability.

Working Principle

The CKRD4810 uses a static thyristor as a switching device. The thyristor has two terminals; one is the signal input port and the other is the load output port. When an electrical current is applied to the signal input port, the thyristor turns on the output port and provides the necessary energy to the load. In order to turn off the relay, the current in the signal port must be reversed and the thyristor must turn off.

The CKRD4810 also offers over-voltage and over-current protection, allowing the user to control the current and voltage to within a safe range. The relay can be triggered by either a switch or a voltage signal, and can be adjusted to suit the specific application. With its integrated self-diagnostic system, the CKRD4810 can detect faults and alert the user when a condition is out of range.

Features

The CKRD4810 has a wide range of features that make it suitable for industrial applications. It offers a low input power of 1.5W, is highly reliable with a long operating life of up to 100,000 switching cycles, and is resistant to shock and vibration. It has a small and slim design, with a height of only 48mm and a width of 40mm. The CKRD4810 has an impressive on-state contact resistance of 5mΩ, a maximum switching surge voltage of 60Vp, and a maximum switching temperature of 105°C. Additionally, the CKRD4810 is easy to install and requires minimal maintenance.

The CKRD4810 is a reliable and efficient industrial-grade solid state relay. With its wide range of features, it can meet the needs of the most demanding applications, providing reliable and high-performance operation.
