DMWD Low cost single phase solid state relay SSR-25AA
Input voltage 80-250V AC
Load voltage 24-380V AC
Load current 25Amp
25A 80-250V AC to AC solid state relay (SSR) features high structural strength, good impact resistance, and strong shock resistance. The SSR offers a reliable switching the commercial and industrial loads, such as computer peripheral interface device, printing machine, molding machine, food machine, packaging machine, and so on.
- Built in RC absorption
- Photoelectric isolation
- SCR output
- LED indicator for operation status
- Panel mount
- Zero-crossing switch type
- UL Approved, CE Compliant to EN60950-1
Note:
* When the load current is higher than 10A, a heat sink must be installed to the solid state relay, or the SSR relay should be mounted on a metal base plate with heat dissipation effect, and the thermal grease is applied between them.
* When the load current is 40A or more, a fan cooling radiator or water cooling radiator must be equipped.
* Heat sink is included.

This unit was purchased to control a 20 amp rated heater which doesn't really draw that much. Even though it was being operated below its stated current rating with the heatsink in place, this unit failed after a couple of months. Failure mode was severe overheating resulting in the unit going up in flames. Fortunately circuit breakers tripped before any damage occurred. If you must have a solid state relay, I recommend getting one with a current rating much higher (at least 50%) than your requirements. Better yet, for such high current requirements, there are actual physical relay units available that should be more reliable.

Exactly as advertised. Shipped fast enough, packaged well enough and works fine.I used this to run my well pump using a 110V trigger from an electronic pressure switch unit. I wanted to use this to power the well pump as it will be more bullet proof on the amperage running the well pump, though the well pump is only at 4.5 amps. If you have a heavy amp draw you might consider adding a little computer fan to the heat sink and make it more bullet proof to heat. Good little unit, good price and very handy.

Easy installation. The relay in the thermostat makes more sound than the SSR-25AA

This relay bleeds current badly. There is a reason for the heat sink. Would not work at all in my application. I went to an electro-mechanical relay, and everything is working well and staying cool.

I'm using it for an HVAC booster fan. I used an AC circuit off my Carrier furnace meant for an air purifier to trigger the relay. Don't even consider using the circuit directly you may blow a very expensive control board.
