Solid State Relays

Solid state relays (SSRs) are devices in the electrical industry that use solid state devices such as transistors, silicon-controlled rectifiers, thyristors, or triacs to switch an alternating current or direct current. SSRs have no moving parts and are inherently much more reliable than mechanical relays. G3VM-21PR10(TR) is one of the most popular SSRs in the market.

G3VM-21PR10(TR) Application Field

G3VM-21PR10(TR) is a single-channel, AC- triac type, non-zero crossing, zero voltage switch, 20A SSR. This SSR is suitable for small signal and low power control applications. It is widely used for applications in industrial controllers, air conditioners, UPS (uninterruptible power supplies), PLC systems, computer peripherals, and other electronic control systems.

G3VM-21PR10(TR) is also available in a Zero-Crossing type variant (which is suitable for high power applications). This SSR switches AC signals with high precision and is highly reliable when used for motor control and heating load control applications.

G3VM-21PR10(TR) Working Principle

G3VM-21PR10(TR) has a built-in TRIAC that acts as a semiconductor switch. It works by modulating the speed of an alternating current motor to regulate the flow of power from the input of the SSR. When the input voltage reaches a certain threshold, the SSR turns on and supplies power to the load. The amount of power supplied to the load is determined by the amount of time the TRIAC is activated.

When the TRIAC is activated, a voltage applied to the gate enables the conduction of the input current through the TRIAC and thus, the load current. When the gate voltage is removed, the TRIAC becomes non-conductive and current flow is stopped. This on/off switching of the TRIAC enables the G3VM-21PR10(TR) to provide accurate regulation and control of the power supplied to the load.

The main advantages of G3VM-21PR10(TR) SSR are its ability to withstand high current and voltage loads, its long life, its high speed switching, and its low electromagnetic noise levels, which make it an ideal solution for applications requiring high-precision control and efficient power management.
