CHARACTERISTICS OF INTELLIGENT SOLID STATE RELAY

● Intelligent solid state relay has ultra small volume, metal aluminum alloy shel! exquisite and beautiful appearance, and same installation site with current general electronic solid state relay, as well as direct replacement.

● Intelligent solid state relay can perform automatic sensing on device working state. for example, the load causes leakage and increases the operating current, local short-circuit phenomenon or insufficient heat dissipation condition causing the temperature of the solid relay body rise rapidly, and extreme super heating phenomenon. When the phenomenon occurs, the temperature control of the intelligent micro power control chip of the intelligent solid state relay can automatically reduce the turn-on current of the power device and achieve the thermal balance work, so as to ensure the safety and stability.

● Intelligent solid state relay has ultra wide control voltage, the switch can be started only when the input voltage is very small, meanwhile. it has good compatibility with computer, SCM and other integrated circuits.

● Intelligent solid state relay adopts advanced soft start mode, and has strong anti current impact capability.

● Isolation withstand voltage of intelligent solid state relay is up to 5000V, which can greatly improve safety and prolong service life

TEMPERATURECOMPARISON TABLE (TABLE1 TEMPERATURE THERMAL PROTECTION)

● Adjust the load current automatically when temperature achieve more than 110 degree centigrade, Reduce power output to reach thermal equilibrium, so there is no moderate thermal breakdown, service life can be increased.

● When reused next time, intelligent solid state relay’s electrical property can recover automatically, while the ordinary solid state relay can’t be resume normal work after the temperature is more than 110 degree centigrade.

TABLE2: HEAT BALANCE INSIDE OF THE SHELL- INTELLIGENT BALANCE OF THE ENVIRONMENTAL TEMPERATURE

● When Ordinary solid state relay and temperature control switch is working, it produce over temperature protection and turn off the power supply automatically, will cause the intermittent work of output power.

● When the I-SSR works, will have the thermal equilibrium function while produce over temperature to ensure continous work.

Precautions:

● When selecting a product, there should be a margin in the current grade according to the nature of the load. (For resistive load, it can be selected according to 50% of the load current. For inductive or capacitive load, it can be selected according to one-third of the load current).

● According to the relationship between load current and ambient temperature, when the ambient temperature is high or the cooling conditions are not good. The current capacity should be increased, the volume of the radiator should be increased, or forced air cooling should be added if necessary. In order to prevent short-circuiting of the load during use, it is required to connect a fast disconnect switch or a fast fuse corresponding to this product in series in the load circuit.

● During installation, the contact surface between the radiator and the product must be flat and clean, and a layer of heat-conducting silicone grease should be evenly coated on the surface, and then tightened symmetrically with the fasteners attached to the product to achieve the best heat dissipation effect.
