Solid state relays (SSRs) are used for switching resistive and inductive loads and outperform the conventional mechanical relays with great advantages. The life cycle with millions of operations, the high switching speed without mechanical or electrical noise, no dangerous sparks or wearing, and the low power needed for switching make the solid state relays a perfect choice when high control accuracy is fundamental.

 Heat Dissipation

The SSR generates heat during its conduction. This heat must be dissipated to avoid SSR failure due to over-heating. The nominal SSR load specification assumes the use of a suitable heat sink. Without a heat sink the allowed load current is substantially reduced. The user may calculate the needed heat sink (please see user manual) or use the suggested heat sink. For better heat transfer, a thermally conductive paste must be used between the SSR and the heat sink.
