Solid State Relay with Heatsink Integrated up to 60A
This slimline solid state contactors present a unique opportunity for panel space savings thanks to their very slim footprint. The DIN rail mount solid state relay is the ready-to-use range that is provided with an integrated heatsink with DIN rail clamps. The radiator is oxidized black and the surface is mirror-finished. The smallest footprint occupies only a width of 17.5 mm with ratings up to 60A. The power and control terminals allow for safe looping of cables. Spring loaded pluggable control terminals are an option when faster installation time is required.

A margin should be left when selecting the voltage and current of the solid state relay.
For resistive load: the current is selected according to 2.5~4 times the load current, and the voltage is selected according to 2~2.5 times the load power. Inductive load: current is selected according to 3-7 times load current, voltage is selected according to 2.5-3 times load voltage.
According to the relationship between load current and ambient temperature, when the ambient temperature is high or heat dissipation conditions are not good, the current capacity of the solid state relay should be increased accordingly.
In order to prevent the product from short-circuiting during use, it is necessary to connect a fast circuit breaker or a fast fuse in series with the product in the load circuit.
For inductive loads, a freewheeling diode must be connected to both ends of the load, and a varistor must be connected to the output end (the varistor (MOV) is selected according to 1~1.5 times of the power supply voltage) to prevent the high voltage generated during switching from damaging the solid-state switch.
When the product is installed, it is required that the contact surface between the heatsink and the product must be flat and clean, and a layer of thermally conductive silicone grease is applied to its surface, and then finally the screws set with flat washers and Spring washersare tightened symmetrically to fix.
