AC Single Phase SSR Solid State Relay AC SSR of Single Dual In line
These SSR’s are of the twin SCR type, inherently more reliable and capable of higher overloads before failure than triacs. Heat is developed in a solid state relay due to the nominal voltage drop across the switching device. To dissipate the heat, an SSR must be mounted on a finned heat sink or aluminum plate. An SSR should be located where the ambient temperature is relatively low, since the current switching rating is lowered as the temperature increases. Another SSR characteristic is a small leakage current across the output when the relay is open. Because of this, a voltage will always exist on the load side of the device.
In comparing SSR’s with mechanical contactors, the SSR has a cycle life many times that of a comparably priced contactor. However, SSR’s are more prone to failure due to overload and improper initial wiring. Solid state relays can fail, contact closed, on overload circuits. It is essential that a properly rated, fast blowing I2T fuse be installed to protect the load circuit.
Finned heat sinks are anodized fabrications that come complete with tapped mounting holes and screws. See thermal rating curves and ordering instructions for proper selection.
All SSRL series relays come with a thermally conductive pad mounted on the baseplate. This will significantly improve the thermal conductivity between the heat sink and SSR baseplate. It is also suggested that 10-inch-pounds of torque be used on the SSR mounting screws.
