Profile

Solid state relays, Acronym SSR, is composed of microelectronic circuits, discrete electronic devices, power electronic power devices composed of non-contact switch. With isolation devices to achieve the control terminal and the load terminal isolation. Input solid state relay with a small control signal, to directly drive high current loads.

Usage

Dedicated solid state relay may have a short-circuit protection, overload protection and thermal protection, and combinational logic cured encapsulant users can achieve the required intelligence module, used directly in the control system.

Solid state relay has been widely used in computer peripheral interface devices, thermostats, thermostat, electric heating control, motor control, CNC machinery, remote control systems, industrial automation equipment; lights, dimming, flashing, lighting stage lighting control system; instrument instrumentation, medical equipment, copiers, automatic washing machine; automatic fire protection, security systems, as well as electric power grid power factor compensation capacitor switch, etc., while in the chemical industry, coal mines and other explosion-proof required, moisture, corrosion has a large number of occasions to use .

Feature

Solid state relay is a isolation of non-contact electronic switch, no mechanical contact member in the switching process, so in addition to having a solid state relay and electromagnetic relay same function, but also has a logic circuit compatibility, resistance to mechanical shock resistance to vibration, installation location unrestricted with good moisture mildew anti-corrosion, explosion-proof performance and prevent ozone pollution is also excellent, small input power, high sensitivity, low-power control, electromagnetic compatibility, and low noise and high operating frequency.
