 | All solid state relays emanate heat when operating, and depending on the amount of heat emitted they might need a heat sink to dissipate this heat into the surrounding ambient air. The use of heat sinks allows the solid state relay to operate properly and reliably for a very long time helping it maintain a suitable operating temperature. Sensata | Crydom offers a wide variety of heat sinks for use with our single-phase and 3-phase panel mount solid state relays. With thermal impedance values ranging from 5°C/W to as low as 0.25°C/W, these heat sinks are suitable for mounting 1, 2 or 3 solid state relays handling a combined load current ranging from 10 Amps up to 100 Amps. Heat sinks are available for mounting onto a panel or, depending on the model, into a standard 35mm DIN rail. Custom heat sinks and SSR/heat sink assemblies are also available upon request. |
