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)
