CDG3 three-phase solid state relay
This product is a novel contactless switch assembled and solidified by semiconductor components. The product has a series of advantages such as fast switching speed, high working frequency, long service life, low noise, reliable action, and no spark. It not only replaces electromechanical relays, but also is widely used in digital programmable control devices, motor control devices, temperature regulating devices, data processing systems and computer terminal interface circuits, especially in special occasions where actions are frequently explosion-proof, moisture resistant and corrosion resistant.
Scope of application
This product is a new type of contactless electronic switch, which not only replaces electromechanical relays but also is widely used in digital program-controlled Device, motor control device, temperature regulating device, data processing system and computer terminal interface circuit, especially suitable for frequent action Explosion, moisture and corrosion resistant special occasions.
Advantages of solid state relay
1. Small size, direct driving of high current load with small control signal
2. High quality imported silicon controlled rectifier and advanced support plate are used. Through special welding process, the welding layer is free of holes, and the use is more reliable
three Advanced thermal conductive insulation material is used, with good thermal conductivity, and the thermal conductive bottom plate is not charged, ensuring safe use
4. LED indication and high strength epoxy resin packaging are adopted, with better explosion-proof and moisture-proof performance and beautiful appearance
Features of solid state relay products
The solid state relay consists of a shell, an electronic circuit board, a flame-retardant engineering plastic shell, a metal heat dissipation bottom plate, and a silicon controlled rectifier. use Special optocoupler isolation, with stable and reliable operation, fast switching speed, high working frequency, long service life, low noise Low power consumption, beautiful appearance, convenient installation and use, etc.
Installation conditions
Usage load When the current is higher than 10A, the heat sink must be used, and the heat sink must be connected to the lower plate and heat sink of the solid-state relay Apply heat-conducting silicone grease between mounting surfaces with input control current<20mA, and apply fan for forced cooling above 60A.
