Solid State Relays (SSRs) have become increasingly popular in modern industrial applications, particularly in areas where high safety, high speed switching performance, and long term reliability are required. The LCB126STR is a leading SSR model developed by Listening Circuits USA, which is widely used in industrial, commercial, and residential applications. This article will discuss the application field, working principle and other features of the LCB126STR.
Application Field
The LCB126STR is used for controlling various types of loads in multi-power applications, such as low voltage motors, lamps, solenoids, pumps, fans, and other AC loads. It is specially designed for industrial and commercial use, including applications in automotive, telecom, computer, machine tools, presses, and control systems. Furthermore, the LCB126STR has been approved for use in residential applications, including swimming pools, escalators, star lights, and other light sources.
Working Principle
The LCB126STR utilizes an optically isolated solid state relay to provide isolated switching in both AC and DC application environments. The relay consists of an LED optically coupled to a phototransistor, which is used to conduct current when energized, and then break the circuit when de-energized. The LED and phototransistor are housed in an insulating material called a “barrier”, which ensures that no direct electrical connection exists between the two elements. The phototransistor is typically used to drive a Toshiba SCR (Silicon Controlled Rectifier) or power transistor in its closed loop nature.
The LCB126STR’s LED is typically powered from a control device, such as a microcontroller, while the phototransistor is connected to a high voltage source. When the LED is turned on, the phototransistor is activated, which triggers the SCR or power transistor and the source voltage is applied across the load. The load is then turned on or off depending on the state of the LEDs. The current rating of the LCB126STR is typically between 0.5 and 3 Amperes, with a peak voltage rating of 750V and a maximum switching frequency of 100 kHz.
Other Features
The LCB126STR features low power consumption, high speed operation, and wide operating temperature range, making it suitable for a range of applications. It is also housed in a fully insulated and epoxy coated housing to prevent dirt and dust from getting into the SSR. In addition, the LCB126STR has an in-house surge protection circuit to provide additional protection against power surges and spikes. The compact size and light weight design ensure the ease of installation and reduce the cost of customer system design. All these features make the LCB126STR the perfect choice for a wide variety of control applications.
Conclusion
The LCB126STR is an advanced and reliable SSR suitable for a wide range of industrial, commercial, and residential applications. It provides high speed switching performance, low power consumption, and wide operating temperature range. In addition, the epoxy coated housing and in-house surge protection circuit provide additional protection to ensure long-term reliability. The LCB126STR is definitely the perfect choice for any control application.
