Product Description

l Principle of Solid State Relay

With combining modern micro-electronic technic with power technic, it is a new non- contactor electronic switch, in the logic control circuit, similar with electric-magnetic relay, it can switch on or off a circuit under the control of trigger-signal.

l Characteristic

SSR is a contactless switch compromising of SOLID STATE components, its feature: safe, high-reliability, contactless, non-spark, non-pollutant, excellent insulation & withstanding high voltage (2.5KV), speed switch-over, and can match for digital-circuit. With sealing with fireproof epoxy, so it is of withstanding voltage, moisture proof, antisepsis and aseismatic and so on.

SSR will be conductive when the voltage is zero. And will cut off when the polential is zero, can get a full sine wave on the load. Therefore the radio interfere from circuits is very little, so can lower the counter electromotive force from the inductancing load (e.g. fan, 3-phase motor etc.), and can lower the surge-current when drive the inductancing load (e.g. incandescent lamp)

l Usage Application of SSR

The terminal from screw of SSR series SOLID STATE RELAY, is of high strength, impact-resistant, anti vibration, little input current can make it contact with computer terminal of digital control circuit, and widely used in all kinds of filed e.g. instrument, machinery, digital-control machine tool and automatizating-equipment, and it is a substitute of AC&DC contactor.

Especially it can be used for pollutant, humid, atrocious environment and occasion that turn on-off continually.

l Specification and Classification

l Basic Features of SSR

It’s input signal can be compatible with both of computer terminal and logic circuit.Design space≥160% face-mount technic.Electric switch-life≥6×107 times.Two trigger model: over zero trigger, random trigger.LED indicates work-state.Build in an absorbing circuit of resistor-capacitor.According on request, can be used for 3-phase or can increase scarcity phase protectionWorking environment:-20°C-80°C.Acting responding-time: ON<10ms/OFF.

l Cautions for Operation

Load current can’t exceed 60% of rated current in resistive-load circuit.Load current can’t exceed 40% of rated current in inductive or capacitive-load circuit. When it is used to control inductive load, must consider the startup of the road: because the inductive load must bear a 6-time of anti peak value voltage.When a current pass the SSR, the SSR will have a voltage-lower, so it will generate a joule-heat, especially a larger current, it needs a radiator when the current is 10A, while the current is larger than 40A, it needs water-cooling or fan-cooling.Over current or short-circuit will result in a permanent damage for the controlled silicon of CCR, therefore must have a fast-acting fuse device, or circuit-breaker.It can parallel connecte a voltage-sensitivity resistor (piezoresistance) for over voltage protection. The voltage-sensitivity resistor also can be built in SSR as requested.
