Solid State Relays (AC Switching)
Solid-state relays (SSRs)are electronic switches devoid of moving parts, ensuring prolonged operational life. These devices utilize power semiconductors like thyristors for rapid and reliable switching of AC or DC loads. Renowned for their fast switching speeds and absence of physical contacts, SSRs excel in applications where electromechanical relays may falter.

In a solid-state relay (SSR), "control voltage" refers to the input voltage range used to control the switching state of the relay. The control voltage is the signal voltage used to drive the SSR. By applying an appropriate voltage to the control terminal, the internal electronic circuit of the SSR operates, thereby controlling the on/off state of the output terminal.
In a solid-state relay (SSR), the control voltage refers to the input voltage range used to trigger the relay, such as 3-32V DC or 90-280V AC (220V ac Solid State Relay). 3-32V DC is suitable for low-voltage DC control, such as PLCs or microcontrollers, while 90-280V AC is suitable for industrial AC control. The control voltage must be within the specified range, and the type (DC or AC) must match the relay; otherwise, it may not function properly.
Greegoo is enjoying a brisk demand in the overseas market for high quality. We are using triacs for 10A, 25A and 40A, 40A and more are using SCR output, T3 copper base, ON brand optocoupler, integrated PCB design and new but perfect electronic components to guarantee the quality of Greegoo's Solid state relays.
The main differences between Solid State Relays (SSR) and Electromechanical Relays (EMR) lie in their structure and performance. SSRs have no mechanical contacts and use semiconductor devices for switching, offering longer lifespan, faster switching speeds, and noiseless operation, making them suitable for high-frequency operations and harsh environments. EMRs rely on electromagnetic coils to drive mechanical contacts, resulting in slower switching speeds, shorter lifespan, and noise during operation, and they are more sensitive to vibration and shock. SSRs consume less power and are ideal for applications requiring frequent switching, such as heating and motor control, while EMRs are suitable for general switching applications, especially where electrical isolation is needed.
A margin should be left when selecting the voltage and current of the solid state relay. For resistive load: the current is selected according to 2.5~4 times the load current, and the voltage is selected according to 2~2.5 times the load power. Inductive load: current is selected according to 3-7 times load current, voltage is selected according to 2.5-3 times load voltage.
