Review: Works perfectly for my application - Works like a champ. I have 240V on the load side and it is being switched by a 110V thermostat to control a hearing eleme in my solvent tank. I used a very large heat sink on it from an old PC because the heating element is 5500W so I wanted this to stay cool and it worked. Hopefully it lasts a long time since the heat sink is keeping it nice and cool. I would definitely order this again, it works perfect and was easy to install and hook up. The only thing I don't really care for is the way the clear cover fits when wires are connected, it is just a friction for which is not really that great, I would prefer a more positive locking cover but I can make one with a 3d printed so not a deal breaker IMO. It is under that heat sink in my picture.
Review: Solved a low voltage drop out with conventional relay - I used this product for a waste oil heater in my workshop. I found that, whenever I would work an automotive hoist, or the a/c compressor would cycle, the voltage fluctuation in the building caused the 8 pin relay inside the machine to trip (original relay in my hand in the picture I’ve posted). It’s a traditional relay with very little tolerance for voltage fluctuations. When the voltage dropped, the electromagnetic coil would release, and the oil pump would stop and cause the machine to set a light. This was driving me nuts, because if I wasn’t quick enough to catch it, the fire would extinguish. I installed two of these solid state relays to replace the single 8 pin. They completely fixed the issue thanks to their wide voltage tolerance. No more resets. Before this I tried a UPS power backup and a line conditioner to no avail (the line conditioner helped a little but not always). Oh, and the relay led lights come on anytime it has power on the control side. The output side has nothing to do with the lights. Overall quality seems high. I’m impressed. I wasn’t excited about an import relay, but these really seem like they are well made in all respects.
