Been installed for about a year now and so far no issues. If you use it to control a motor you have to run a fly back diode to keep from ruining the SSR. Thats what the 3 black rectangles with red a black wires running to them are. Gonna buy another one of these to pwm a windshield washer pump for water injection pre turbo (cheap turbo, dont care about the compressor wheel) Review: Very handy for stepping power in pwm signals. - I have one of this brand solid state relays running my pickups electric fan at 12v with 250 hz pwm. Works great for this purpose and you can even get heat sinks for them. It's been on the truck over a year now and ~ 9000 miles, mostly in the heat. ## Features - ♥【What You Get】Each package With 2 mini bag of thermal grease which apply on the back of the SSR to make the temperature dissipate faster. - ♥ Product Name: solid state module relay SSR-100DD, 3-32VDC/5-220VDC ; Current & Frequency:100A,50/60Hz. - ♥ Total size (approximate):58 x 45 x 32mm/2.3" x 1.8" x 1.26" (l*w*t); Net weight:116g; Material:metal, plastic, electronic parts. - ♥ SSR Application: with a switch no spark, no noise,high switching speed,anti-corrosion,moisture-proof,anti-vibration,long life.high reliability,electromagnetic compatibility and other characteristics. - ♥ Solid state relay ideal for automatic process control application, a must component for temperature controller and other machinery control system.Note: Motors are capacitive loads and require 10 times the rated current specification.

Works great for this purpose and you can even get heat sinks for them. It's been on the truck over a year now and ~ 9000 miles, mostly in the heat. ### ⭐ Very high internal resistance *by J***R on August 6, 2021* 100 amp SSR: I measured an internal resistance of 0.25 ohm with a 5 amp load current. For small currents, the resistance is approximately linear. If I tried to run 10 amps through it, it would dissipate 25 watts and drop 2.5 volts (if the resistance stays linear). A good heat sink is required. If I tried to use it with a 50 amp load current, it would either melt or burn up trying to dissipate over 600 watts. This SSR is only useable at 10% of its load rating. Observe the polarity markings. Current must flow from + to - within the relay. Warning: It's a short circuit if wired backwards. The device will not operate properly with an AC load; it acts like a diode. I've tested a dozen of the 25A relays, and they all have the same internal resistance characteristic as this 100A unit. ## Frequently Bought Together - CG Solid State Relay SSR-100DD DC to DC Input 3-32VDC To Output 5-240VDC 100A Single Phase Plastic Cover… - CGELE 3PCS Aluminum Heat Sink SSR Dissipation for Single Phase Solid State Relay 10A,25A,40A Black Radiator… --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/250902016-cg-solid-state-relay-ssr-100dd-dc-to-dc-input](https://www.desertcart.co.uk/products/250902016-cg-solid-state-relay-ssr-100dd-dc-to-dc-input) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-16*
