Thousands of cycles, no issues.

I have been using this for over a year to allow a 24v DC control circuit to cycle a 120v 750w AC bed heater for a 3d printer on and off. No problems.

RV use, works perfect 👍😎🎉

During a camping trip in 98°F heat, our relay malfunctioned, causing the air conditioner to fail. Replacing the relay completely resolved the issue. Two years have passed since the replacement with no recurrence. Installation was straightforward, taking approximately 20 minutes to complete.

Works great for a 3D printer AC bed heater

Been using it almost 20hrs a day for over a month to power on and off my 1000w AC bed heater on my 3D printer. Mounted it using the included heat sink and it's not even warm after a long print at 100c bed temp. I connected the DC straight to my octopus pro control board. The AC is connected straight to a current protected AC power strip tthrough a 120c thermal fuse just in case.

Light tells you there’s a load

Nice ssr. Relays do go bad; I have two old ones neither was working so I had to buy a new one. I like this one because of the red led when the circuit is working and the load is applied. My old ones didn’t have that and I had to use a volt meter to figure out what was going on. Not hard to do but one more thing.
