G3VM-41QR10TR05 Relays

Solid state relays (SSRs) are electrical devices used to control circuits electronically, usually replacing mechanical relays. Unlike traditional mechanical relays, SSRs contain no moving parts, allowing for increased service life and improved reliability. The G3VM-41QR10TR05 is an SSR that offers both optical input and output isolations of 5300Vrms for reliable load control.

The G3VM-41QR10TR05 operates with a maximum input of 24V for on/off control and has a maximum load current of 10A using a zero-cross circuit. It is for DC-load applications and can be used in many industrial and home appliances, including refrigerators, washing machines, and air conditioners. It is also suitable for electronic heating element control and automotive light control applications, where optical and electrostatic discharge protection is critical.

The G3VM-41QR10TR05 works on the principle of thyristor conduction switching. This process is enabled when a small voltage is applied to the Gate terminal, allowing the thyristor to enter the conducting region. Once the thyristor is in the conducting region, it provides a controlled path for the main current to flow, switching the load on or off, depending on the Gate voltage.

The G3VM-41QR10TR05 is also designed to reduce inrush current, as well as provide reliable operation of heavy loads in noisy industrial environments. This is thanks to the zero-cross detection feature, which prevents the G3VM-41QR10TR05 from turning on or off during the peak of the AC sine wave, thus reducing the inrush current to a small fraction of a rated value.

The G3VM-41QR10TR05 is also designed for a wide range of operating temperatures, from -20 to 80°C. This allows the SSR to be used in a variety of environments and applications. Additionally, the SSR is designed to withstand overvoltage and transient voltage conditions, which improves its reliability and safety.

In addition to its reliability and wide operating temperature range, the G3VM-41QR10TR05 also offers a number of protection features. These include an overvoltage protection feature, which guards against unexpected high voltage spikes, as well as an overcurrent protection feature that limits the steady state current flowing through the thyristor and output terminals.
