Introduction to LCB717 Solid State Relays

A Solid State Relay (SSR) is an electrically controlled switch used to switch on and off a wide variety of electrical loads such as motors, solenoids, lights and more. The LCB717 is a type of SSR featuring high frequency switching and high level switching performance. This reliable and robust SSR is commonly used to switch high-frequency current with very low switching loss.

Applications

The LCB717 is especially suitable for applications of switching DC components such as motors, solenoids, lamps and more. The inverter units of many industrial machines and electronic equipment make use of the LCB717 SSR. In process control applications, LCB717 can be used in combination with a precision control system to achieve accurate and timely response for components such as electromagnets, servo motors, DC motors and more.The ability to handle high current and high voltage along with its superior switching performance makes the LCB717 an ideal choice for lighting control applications such as fluorescent lamp circuits, LED lamps and incandescent lamps. In addition, it is also suitable for use in pulsed power applications, as well as other power conversion circuits.

Working Principle

The LCB717 is based on the “non-contact switching principle”. This means that the SSR utilizes a switching element (Electronic Switch) to cut off and restore the electrical circuit without a physical contact between the two sides.In the LCB717 SSR, two electronic semiconductor switches are used, namely an AC/DC switch (SW1) and a DC/AC switch (SW2). The input is applied to the AC/DC switch SW1 which, in turn, opens or closes depending on the input. The DC/AC switch SW2 is then switched on or off after the AC/DC switch SW1 has opened or closed. When both switches are simultaneously opened, the circuit is closed and current flows.The LCB717 relies on the latest temperature protection devices, temperature control designs, and reverse connection protection design to safeguard the unit from any kind of over-temperature failure, protection against short circuit, and reverse connection protection.

Conclusion

The reliable and robust LCB717 SSR is designed to switch high frequency current with very low switching loss. It is especially suitable for applications of switching DC components such as motors, solenoids, lamps and more, and can also be used for lighting control, pulsed power applications, and other power conversion circuits. The LCB717 is based on the “non-contact switching principle”, wherein two electronic switches are used to cut off and restore the electrical circuit without a physical contact between the two sides. The accurate and secure structure of the LCB717 makes it an ideal choice for operation in harsh environments.
