TL-SSR – 12V / 100A DC Unidirectional Solid State Relay (SSR)

Sale price$39.99

A solid-state relay (SSR) functions similarly to a mechanical relay but uses electronic components instead of moving parts, making it quieter and spark-free. SSRs have a much longer lifespan and require only a few milli-amperes to stay in the ON state, while electromechanical relays need higher currents to power the coil.

This SSR is ideal for battery-operated equipment and finds typical applications in RVs, boats, vehicles, or any 12V system.

This SSR fits in a standard ANL fuse holder, as depicted in the pictures.

DISCLAIMER: The ANL fuse holder shown in the pictures is for display purposes only. You will only receive the SSR.

TL-SSR-12V

I bought a couple of TL-SSR-12V to use in a 12V power distribution panel. The SSR works as described. Very helpful tech support.

High Current Battery Disconnect

Due to space constraints on our racecar we had to build a custom battery box, the ThornWave TL-SSR's are easy to use in parallel for a master safety disconnect and handle the 700A+ at 16.8V draw without even warming up.

Great addition to my system

I bought this to control a backup generator. The relay is configured to kick on my back up generator when my solar battery bank reaches a low SOC, triggered by a set voltage. This takes care of charging my batteries even if I am not home. I have tested it several times as my battery bank very seldom reaches the low voltage trigger I have set. It has on two occasions triggered, and successfully charged my batteries with the generator, So it does work flawlessly.

I love the fact that this relay is solid state. It is so easy to install, and the PowerMon App makes configuring a breeze. It is one of the best shunt and relay setups I have ever seen. The TL-SSR Relay is super versatile that can do about any task that a relay can do. From triggering fans, lights, generators and much more. This is a terrific value for the price, and in combination with the PowerMon-5S, it is the perfect setup. 5 stars from me!
