Solid state relays are electronic switching devices that contain no moving parts and rely on semiconductor technology to switch currents. The ED24C5 is a 24 VDC solid state relay that is designed for switching AC or DC loads, allowing for the efficient control of SCR circuits, motor loads, power conversion appliances, and other high power loads.

ED24C5 Application Field

The ED24C5 can function in both AC and DC controlled circuits and is suitable for resistive, inductive, or capacitive loads. Motors, transformers, solenoids, electromagnets, and pumps are some of the most common inductive loads for which the ED24C5 can be used. Additionally, the ED24C5 is approved for use in UL/cUL, CE Marked applications, is able to operate up to 85°C operating temperatures, and has the ability to withstand high reverse voltage or transient spikes up to the max load voltage.

The ED24C5 is an innovative device that can be used in most industrial and HVAC applications, including power supply, electric heating, lighting, air conditioning, pumps, telecom, motor control, insulation monitoring, fan control, AC power, water temperature, and many other applications. The ED24C5 features low energy consumption and a low power consumption rate of up to 5 watts during operation. It is also able to withstand shock, vibration, and electromagnetic interference.

ED24C5 Working Principle

The ED24C5 works based on a switching principle. When the load being controlled requires a larger voltage or current than can be supplied by the power supply voltage, the ED24C5 switches in the load. This process occurs when the voltage or current present in the power source exceeds the cut-off level of the ED24C5 control circuit. When the power source voltage reaches the cut-off level, the ED24C5 opens the switch and prevents any current from flowing through the load.

The ED24C5 can also be used as a contactor circuit. In this mode, the ED24C5 is used to control high-voltage loads. When the contactor circuit is in the closed state, the ED24C5 works by providing a direct path for the electric current to flow from the power supply to the load. The ED24C5 also provides electrical insulation between the power supply and the load. This insulation is designed to protect the power supply from overcharging or damage to the load in the event of a circuit overcurrent.

The ED24C5 features unique overload protection and a high switching power of up to 2,200VAC. The ED24C5 has an ESD (electrostatic discharge) protection level of 4kV, which allows the device to protect itself from ESD events. Additionally, the ED24C5 is designed with a built-in thermal protection circuit that prevents damage from excessive temperatures. The ED24C5 also features a built-in zero-crossing detector, which ensures that the switching control circuit operates accurately.

Conclusion

The ED24C5 is a 24V solid state relay designed for AC and DC loads that need to be switched in order to perform their desired functions. It can be used for motor control, power conversion, insulation monitoring, and other high power applications. The ED24C5 has a high switching power of up to 2,200 VAC, and is designed with overload protection, ESD protection, and thermal protection. Additionally, the ED24C5 is UL/cUL, CE Marked approved, and is capable of withstanding up to 85°C operating temperatures.
