## Description

TWTADE SSR-25 DD 25A DC 3-32V to DC 5-60V SSR Solid State Relay + Heat Sink: desertcart.com: Industrial & Scientific

Review: Good relays after a year of use - I have two of these in enclosed but outdoor locations. Working well after over a year.
Review: So far so good - I'm using two of these to control a 110v 1300watt heating pad that draws around 11amps and a 110v 550watt 5amp 635cfm exhaust fan. I havent ran the heating pad yet, but the fan does great. I have the heatsinks cooled by a 24v fan and 150c thermal fuses fixed to both of them in case they fail. If I ever have any issues, I'll report back with updates. Edit: I guess I should mention I'm triggering them with 24v DC off of a PSU. Low voltage side is negative from the SSR to the negative on the PSU and positive from the PSU to a switch to the SSR. 110v side interrupts the LINE wire for the exhaust fan.

### ⭐⭐⭐⭐⭐ Good relays after a year of use
*by S***E on November 24, 2025*

### ⭐⭐⭐⭐⭐ So far so good
*by R***E on October 5, 2022*

### ⭐⭐⭐⭐⭐ It works reliably for one year now
*by P***D on May 8, 2021*

I use it in the garage ceiling to control multiple LED light bulbs from the light output of the garage opener. It works reliably for a year now. As one may know, if you use LED bulbs for the garage opener light, it decreases the range of the openers (if they work at all) and in time it will burn the internal wireless controller of the garage door opener. The solid state relay I use it as a 'separator' to route the AC circuit of 3 LED bulbs directly from the 120V house circuit and command it with the garage door opener. I mounted it in the garage ceiling and almost forgot about it. Now my garage openers range from the cars is more than 150 ft.
