DDソリッドステートリレー(40DD)。

Im using one of these 40 amp SSRs to PWM a transmission cooler fan up under my jeep. Been installed for about a year now and so far no issues. If you use it to control a motor you have to run a fly back diode to keep from ruining the SSR. Thats what the 3 black rectangles with red a black wires running to them are. Gonna buy another one of these to pwm a windshield washer pump for water injection pre turbo (cheap turbo, dont care about the compressor wheel)

This is an excellent relay, works perfectly and little noise (40db or so) when turning on

Good quality item for the price, came well packaged with all the necessary hardware included

Great contactless and silent relay, this will last forever if its well configured and silicone paste applied for heath transfer

Got 2 of these, One just shorted the output all the time so I always had 120VAC on the output (even with the control wires disconnected) the other 1/2 worked in that it only put out 60VAC when no input signal was given, then called up to 120V when a signal was sent
