Solid State Relays (SSRs) are used to implement electrical switching processes, normally with low input currents and within the parameters of their designed application field. In particular, the G3VM-351H(TR) SSR model is used in a very elaborate and efficient manner, through its very specific characteristics. This SSR allows input signal current levels as low as 8 mA, for the photocoupler portion, and is controllable up to 40 mA for the output side.

One of the main advantages of the G3VM-351H(TR) SSR is its highly precise, zero-voltage switching behavior. This allows for implementation with very precise voltage and current control, even in delicate and difficult-to-control electrical environments. The G3VM-351H(TR) also has thermal protection, with a dielectric strength of 250 VAC, making it resistant to exterior contamination, and a response time as low as 12 milliseconds. Further advantages include constant ON resistance, small body dimensions (25 mm x 7 mm x 5 mm), and unmatched load capacity (up to 35A and 250 VAC).

In terms of these features, the G3VM-351H(TR) is an ideal SSR choice for a wide array of applications. These applications range from motor control, to fans, air-conditioners, and kitchen hoods, to industrial ovens, photoelectric switches, and kitchen-appliance control. The G3VM-351H(TR) SSR can also be used in solar cell ripple-control and heating-systems applications. Its highly reliable thermal protection combined with its zero-voltage switching capabilities ensure its durability in both high-temperature and low-temperature applications, while its ETU circuit element provides further sureties.

The working principles of the G3VM-351H(TR) SSR are quite simple. The G3VM-351H(TR) SSR utilizes an ambient light-activated photocoupler circuit, which is connected to an ETH circuit element to form an optically isolated switch. The ETH circuit element is a power electronic device which is used to satisfy output voltage and current requirements and electromechanical actuators. This device is responsible for the zero-voltage switching and for providing thermal protection to the system.

The G3VM-351H(TR) SSR is triggered by an input current of 8mA (or higher) from the photocoupler. The output voltage and current of this SSR is determined by the load current and voltage requirements of the specific application. A built-in thermal protection circuit eliminates the need for external safety measures. This SSR can safely control current levels up to 40mA.

To conclude, the G3VM-351H(TR) SSR provides a very high level of accuracy and reliability when it comes to electric switching processes. This SSR has applications in a wide range of industries, power electronics, and domestic appliances. Its unique and precise zero-voltage switching characteristics and its integrated thermal protection circuit make it suitable for handling a variety of electrical environments and load conditions. The input signal current levels required to trigger this SSR are comparatively low and it has a very fast response time. This makes the G3VM-351H(TR) SSR a popular and ideal choice for many different applications.
