Introduction

Solid state relays are reliable and cost-effective devices, and are widely used in many industries. LH1511BABTR is a solid state relay on the market, with a wide range of applications and excellent performance. In this article, we will explain the application field and working principle of LH1511BABTR.

Application Field of LH1511BABTR

The LH1511BABTR is a single-phase AC solid state relay with a load current of up to 15A. It is widely used in electric heating equipment three-stage temperature control, generator set control, switching power supply and other fields. In addition, it can also be used in light industry equipment, LED scoring machine, temperature control equipment and so on.

Working Principle of LH1511BABTR

The working principle of LH1511BABTR is that an opto-isolated tri-state MOSFET control circuit is used, which is an optoelectronic circuit composed of an LED and an optocoupler. When the control signal is applied, the LED is distorted to generate a current, which is then used to turn on an optocoupler switch. The toggle switch then turns the MOSFET switch on and allows current to flow through it. The relay is then activated and the load can be powered on.

Advantages

The LH1511BABTR solid state relay offers several advantages. It features LED indicators for under-voltage, over-voltage or overload protection, as well as short circuit protection. It also has a wide operating temperature range, and it is highly reliable with a long service life of up to 100,000 cycles. It also has high switching speed, low power consumption, high sensitivity, low thermal resistance and input leakage current.

Conclusion

LH1511BABTR is a single-phase AC solid state relay with a load current of up to 15A. It features LED indicators for under-voltage, over-voltage or overload protection, as well as short circuit protection. The relay is widely used in electric heating equipment three-stage temperature control, generator set control, switching power supply and other fields, and offers many advantages including high switching speed, low power consumption, high sensitivity, low thermal resistance and more.
