YUANKY SOLID STATE RELAY 3A 5A SINGLE ROW IN LINE 6-35MA DC CONTROL AC 380VAC THREE PHASE SSR SOLID STATE RELAY

Brief Introduction of Solid State Relay

Character of Solid State Relay

The solid state relay owns high reliability: there isn’t any mechanical part inside SSR. and it uses totally-enclosed encapsulation structure Therefore, SSR owns characteristics of resistance to shock, moisture resistance, corrosion resistance. long service life and reliable operation. SSR owns low level of noise: each AC SSR adopts zero-crossing triggering technology. So that it could reduce dv/dt effectively in the circuit SSR owns fast switching speed; The switching speed of SSR is much faster than the one of mechanical switching with a making and breaking time reaching tens of microseconds for DC solid state relay. SSR could be compatible with logic circuit like TTL CMOS. etc.

Basic Character of Solid State Relay

Input signal could make computer terminal and digital logic circuit compatible

Optical isolation between input and output circuit, with isolating withstand voltage of 4000V

Two specifications: zero-crossing triggering and random triggering

LED indication for working condition

Built-in resistance-capacitance absorption circuit

Dielectric withstanding voltage: > 2KV

Dielectric insulating strength: > 50MQ

Actuation time: ON > 10ms/OFF < 10ms

Working environment: -20℃ ~+70℃

Application

SSR series solid state relay adopts flame resistant engineering plastic case, epoxy resin encapsulation, screw thread educing terminal connection with high-strength structure, impulse resistance, high shock resistance performance, small driving current for input terminal and convenient connection with computer terminal and digital control circuit. the product is widely used in automatization control fields such as petroleum, chemical industry instrument and meter, pharmacy machine, food machine, packaging machine. plastic machine, numerical control lathe, entertainment facility,etc.,especially for severe environment full of corrosion and moisture or requiring explosion-proof and dust resistance or places demanding frequent switching.

Operation Notice

Resistive load could not exceed 60% of rated current.

Inductive or capacitive load could not exceed 40% of rated current.

Electric machine load could not exceed 20% of rated current.

Proper radiator adapted to the working requirement of solid state relay should be equipped, the allowance should be widened when the load radiating condition is not so good Short circuit load is not allowable.

Over Voltage Protection: over current and short circuit are the main reasons for permanent damage of output controllable silicon in the SSR and using fast fuse and air switch is one of the methods for over current protection, fuse is also available for small capacity.

Over Voltage Protection: It could adopl parallel voltage-dependent resistance(MOV), the MOV area decides the absorption power while its thickness decides the protective voltage value, generally, 471/10D voltage dependent resistance for 220V series SSR, 681/10D voltage dependent resistance for 380V series SSR 821/10D voltage dependent resistance for 480V series SSR.
