SSR 10DD 25DD 40DD 200A 600A Single Phase DC Control Solid State Relay with Heat Sink, 3 32VDC Input, 220VDC 600V Output, 10A 25A 40A Current Rating 150DD 220V

relay Attention:Solar equipment is a mixed load, we do not recommend using solid state relays.If you want to try, you need to buy a solid state relay with 10 times the current.At the same time, if the solid state relay does not work normally on the solar equipment, we do not provide return service.

PS:OurHeatSinkinclude2screws forinstallheatsink andapackofthermalcompound isappliedtothebottomoftheSSR NOTICE: The inside of the solid state relay is a semiconductor. A semiconductor switch is a non physical contact switch. if use a multimeter diode or resistor to test ,it always show a high impedance state, multimeter light red . According to the conventional detection methods of solid state relays: a load is required to test the switching state. Using an incandescent lamp as a dummy load is an obvious way to test continuity.
