Solid State Relays (SSRs) are popular electronic components that are used to switch high power AC or DC loads safely.

The G3VM-21LR10(TR05) is a type of SSR that is designed for use in home automation and heating, ventilation and air conditioning (HVAC) systems. It is a precision miniature Single-in-Line (SIL) package SSR that offers low on-resistance, low drive power consumption and wide operating temperature range. It has a high surge current capability and is also immune to voltage transients.

The G3VM-21LR10(TR05) is designed to be used in applications that require an AC input voltage of 250 volts or less. The relay itself has an AC switching capability of up to 20 amps and a DC switching capability of up to 10 amps. The maximum input switching voltage is 28 volts DC, and the minimum is 4.5 volts DC.

The G3VM-21LR10(TR05) works on the principle of zero crossing detection. When an AC voltage is applied to the input terminals, the SSR will detect the zero crossing point of the voltage waveform. When the zero crossing point is detected, the SSR will activate the output circuit. The output circuit will remain active until the AC voltage waveform reaches the zero crossing point again. The output will then be disconnected, and the SSR will return to its initial state.

The G3VM-21LR10(TR05) offers several advantages over other types of SSR. It has a fast response time, low on-resistance, low power consumption, and wide operating temperature range. The relay can also handle high voltages and can switch almost any load type.

The G3VM-21LR10(TR05) is a versatile, reliable and cost-effective component. It is suitable for use in a variety of applications, ranging from simple on/off control of household appliances to more complex HVAC systems, as well as industrial and medical equipment. Thanks to its zero crossing detection feature, it is also suitable for phase control applications, such as dimming of lighting fixtures, motor speed control, and transformerless power supplies.
