80A 3-32V DC 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.

I have purchased several of these for various projects, they're pretty durable little things. I've had the DC to AC versions survive winter cold, high humidity, and scorching heat inside a greenhouse for example.I've dissected some of these from various brands including DMWD, Fotek, and Inkbird, here are my findings.The DC-AC versions use a MOC3063 opto-TRIAC paired with a power TRIAC to switch the load. The DC-DC versions achieve isolation via a transformer and switching circuit paired with a power MOSFET.Load side power components are appropriately sized given the ampacity and voltage ratings, but I would still recommend purchasing the next size up and actively cooling if you plan to draw any real power.Solder joints look passable and load side traces are pretty beefy.Some of the units are siliconed and potted internally, some are not.All of the power MOSFETs and TRIACs have thermal pads bonding them to the metal backplate.I have not purchased the AC-DC or AC-AC versions so I cannot comment on those.Overall I would highly recommend these if you want to save some money and avoid designing your own switching circuit!
