LAA125LSTR

Solid State Relays

A solid state relay (or SSR) is a type of relay that uses a low-power electric current to control a larger electric current. It uses a solid-state electronic switching device, such as a transistor or thyristor, instead of an electromechanical relay, to control the electric current. It is usually used to allow a low-voltage switch to control a higher voltage circuit.

LAA125LSTR Application Field and Working Principle

The LAA125LSTR is a high-performance solid state relay that provides stable and reliable performance in areas such as burglar alarm systems, lighting control, automated production lines, and other control applications. With its low power consumption and high efficiency, it can be used in various industries to improve safety and efficiency.

The LAA125LSTR is a zero-crossing, triac-output relay with zero-crossing detection and selecting principle. When the control input is below the threshold voltage, the triac output will stay on. When the input voltage rises above the threshold voltage, the current in the load is switched off, and the output is switched off. This ensures that the load is properly switched on and off with low switching losses.

The LAA125LSTR has a wide operating temperature range of -10°C to +70°C, making it suitable for use in a range of industrial environments. It has an insulation resistance of 1000Mohm minimum, and a dielectric strength of 3000VAC minimum, making it reliable and safe for use in high voltage circuits. The package of the LAA125LSTR is designed to ensure maximum heat dissipation and durability.

The LAA125LSTR has an improved shelf life of up to 10 years, and a wide range of input voltage options, making it suitable for a variety of applications. The relay has a built-in overcurrent protection circuit that limits the current under overload conditions, protecting the devices in the system. The LAA125LSTR also has a built-in surge protection circuit to ensure that the device is not damaged during power surges.

The LAA125LSTR is a versatile, reliable, and energy-efficient solid state relay suitable for a wide variety of applications. Its low-power consumption and high efficiency make it a great choice for controlling high-voltage circuits in various industries. With its wide operating temperature range and improved shelf life, the LAA125LSTR can provide years of reliable service.
