CG Solid State Relay SSR-100DD DC to DC Input 3-32VDC to Output 5-240VDC 100A Single Phase Plastic Cover…

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)

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.

100 amp SSR: I measured an internal resistance of 0.25 ohm with a 5 amp load current. For small currents, the resistance is approximately linear. If I tried to run 10 amps through it, it would dissipate 25 watts and drop 2.5 volts (if the resistance stays linear). A good heat sink is required. If I tried to use it with a 50 amp load current, it would either melt or burn up trying to dissipate over 600 watts. This SSR is only useable at 10% of its load rating. Observe the polarity markings. Current must flow from + to - within the relay. Warning: It's a short circuit if wired backwards. The device will not operate properly with an AC load; it acts like a diode. I've tested a dozen of the 25A relays, and they all have the same internal resistance characteristic as this 100A unit.

I have been needing these for a long time and didn't even know it. Mechanical relays fail pretty quick in some applications and have other issues. This works perfectly with a control voltage of greater than 3 volts and is dead silent. No moving parts. The back is an awesome heat sink. Easy to mount and hook up. Love these things just ordered more.

I used the SSR to drive 2 LED backup lights. The SSR is installed under the front seat. I clamped a magnet on the shift rod and a magnetic read switch provides the SSR's input current.

I've killed a couple accidentally because the output is one direction so if you feed in from the wrong direction for too long you kill it. Either toss in a slip of paper or label it better then these would be 5 star all day every day. And they get HOT so scrounge up some old computer heatsinks and JB Weld them on with a thin layer so you get heat transfer.

I run a powder coating oven of of these works great

Arrived non functioning. The output circuit is always on. Fried my induction board with this thing. Will try a different one and test again but as of now, 1 star and I have to buy a new board.

No funciona como un relavador normal energizado o no este se mantiene activado

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

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

Thank you
