Review: Great for pwm control - 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)
Review: Very handy for stepping power in pwm signals. - I have one of this brand solid state relays running my pickups electric fan at 12v with 250 hz pwm. Works great for this purpose and you can even get heat sinks for them. It's been on the truck over a year now and ~ 9000 miles, mostly in the heat.
