Solid State Relays: G3VM-101HR1(TR05)

Solid State Relays, or SSRs, are a type of relays which are actuated by an electric current, rather than by electromagnetism. SSRs are designed with circuitry and components which allow them to be operated using either DC or AC currents in varying capacities. The G3VM-101HR1(TR05) is a particular SSR which has a variety of applications and functions.

Application Field of G3VM-101HR1(TR05)

The G3VM-101HR1(TR05) SSR is a widely used component in sectors such as factory automation, process control and light control. As a high-performance SSR, it is designed with a hybrid heat release design which allows it to be used for driving certain relatively high capacity loads, such as incandescent bulbs, motors and electrical fires. The self-holding construction of the G3VM-101HR1(TR05) also enables it to be used in light switching circuits.

Working Principle of G3VM-101HR1(TR05)

The G3VM-101HR1(TR05) SSR works because it includes a light emitting diode (LED) which is energized when current is applied to its control circuit. This in turn energizes a thyristor, which then restricts current to flow in the power circuit. The resistance in this circuit is determined by the input voltage level, as well as the LED drive current. The solid-state relay is designed with a hysteresis tolerance of 5 to 10 percent for varying input voltages, meaning it can accommodate varying levels of voltage without affecting the switching status.

The hybrid heat release design of G3VM-101HR1(TR05) SSR allows it to operate in both a low power and a high power mode. In the low power mode, the LED is energized first, and once the desired voltage level is reached, the thyristor is activated and allows power to flow in the circuit.The high power mode is activated when the LED is already on, and the thyristor is also activated, also allowing power to flow in the circuit. The SSR can automatically switch between these two modes depending on the amount of current set in the hysteresis.

Conclusion

The G3VM-101HR1(TR05) SSR is a hybrid high-performance SSR designed with a dual heat release design and a hysteresis tolerance of 5 to 10 percent. It can be used for a wide range of applications, such as driving certain high capacity loads, such as motors, incandescent bulbs, and electrical fires. The SSR can also be used in light switches and is able to automatically switch between a low and high power mode depending on the hysteresis setting.
