 The SSR has been sourced from domestic suppliers due to the influx of counterfeit relays coming from China. It is hoped this will reduce the odds of using a relay that is dangerously under-specc'​d. The SSR has been sourced from domestic suppliers due to the influx of counterfeit relays coming from China.

-Without a heatsink __**the example SSR should not be loaded with more than 10A (2.4Kw @240v)**__. The SSR uses the aluminium case as a heat-sink in this application,​ but its thermal capacity is unknown. Use of the ACS to internally switch more than 10A should be thermally tested under controlled conditions. Mounting the ACS to an external heatsink or thermally conductive machine chassis should be expected to mitigate this, but test before commissioning.+Without a heatsink __**the example SSR should not be loaded with more than 10A (2.4Kw @240v)**__.
