Heat sinks for monoblock SSR 10 amp
ECEFast supplies a range of SSR, including lower cost OEM units and premium industrial models. Solid state relays have to reject heat to operate efficiently. Any SSR in still air will switch around 10 amps without cooling, even if it is rated at 40amps. To switch continuously at close to its rating an SSR must have a correctly sized heat sink – and must transfer heat to the heat sink efficiently, and the heat sink must have ventilation. SSRs rated above 40amps require fan forced cooling of the heat sink or be derated for ambient temperature If you have questions concerning your application – call us!
- Two sizes to suit common SSR ratings
- Anodised aluminium construction predrilled and tapped for M4 mounting screws
- Use heat transfer paste under the SSR on assembly
- Allow for ventilation of the heat sink if switching close to the SSR rated current
