G3VM-21UR10(TR05) Relays

Introduction

A solid state relay (SSR) is an electronic switching device that allows for the control of power control in an electrical system. G3VM-21UR10(TR05) is a type of wave soldered SSR which has an integrated heat sink and an internal temperature compensation structure. It can be used for direct switching of a variety of loads, especially those that require high surge current with low power loss.

Application Field

The G3VM-21UR10(TR05) solid state relay is a versatile and reliable device designed to meet the needs of a wide range of applications. It has a wide operating temperature range of -25°C to +85°C and can handle large operating currents up to 25A. It is suitable for applications such as temperature and pressure control systems, PLC and process control systems, and motor drive systems. This solid state relay is also widely used in the medical industry, automotive industry, lighting industry, LED industry, and in industrial automation.

The G3VM-21UR10(TR05) solid state relay offers high reliability and is capable of handling high inrush current load applications up to three times the rated current, making it perfect for applications where current loads vary significantly. It features fast response times, excellent heat dissipation, high efficiency, and superior electrical isolation for enhanced protection against noise and interference.

Working Principle

The G3VM-21UR10(TR05) solid state relay works by using an integrated power transistor to switch the load current on and off. When the input signal is on, the power transistor is turned on, allowing current to flow to the load. When the input signal is off, the power transistor is turned off, which cuts off the load current. This is known as the “on-off” principle.

The G3VM-21UR10(TR05) solid state relay also features a built-in zero crossing detector which signals the power transistor to switch off when the input signal crosses zero. This eliminates the risk of arcing and reduces the stress on the power transistor. In addition, the device features an LED indicator which displays the operating status of the relay.

Conclusion

The G3VM-21UR10(TR05) solid state relay is a reliable and versatile device that is well-suited for a wide variety of industrial and commercial applications. It features a wide operating temperature range and can withstand high inrush current loads, making it a great choice for applications with fluctuating current loads. The built-in zero crossing detector and LED indicator provide added protection and convenience, and make this device a great option for those looking for a reliable and effective solid state relay.
