Review: No funciona como un relavador normal energizado o no este se mantiene activado Review: Im using one of these 40 amp SSRs to PWM a transmission cooler fan up under my jeep. 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) ## 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-25DD, 3-32VDC/5-220VDC ; Current & Frequency:25A,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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08GNSPCND | | ASIN | B08GNSPCND | | Brand Name | CGELE | | Coil Voltage | 3 Volts (DC) | | Connector Type | Screw | | Contact Type | Normally Open | | Current Rating | 25 Amps | | Customer Reviews | 4.1 4.1 out of 5 stars (395) | | Customer reviews | 4.1 4.1 out of 5 stars (395) | | Date First Available | 7 September 2020 | | Item Weight | 0.01 Ounces | | Manufacturer | CGELE | | Manufacturer | CGELE | | Minimum Switching Voltage | 3 Volts (DC) | | Mounting Type | Panel Mount | | Operation Mode | Automatic | | Package Dimensions | 7.39 x 7.29 x 5.21 cm; 0.28 g | | UPC | 774297736507 | | Unit Count | 1.0 Count | | Wattage | 800 watts | ## Product Details - **Brand:** CGELE - **Connector type:** Screw - **Contact type:** Normally Open - **Current rating:** 25 Amps - **Mounting type:** Panel Mount ## Images ![CG Solid State Relay SSR-25DD DC to DC Input 3-32VDC To Output 5-240VDC 25A Single Phase Plastic Cover - Image 1](https://m.media-amazon.com/images/I/71cCjYUKNqL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: What is the maximum frequency this can be turned on and off?** A: This is mainly in reply to the incorrect info provided by another person. The stated on/off is 10ms, therefore it takes 10ms to turn on and another 10ms to turn off, totaling 20ms, or 0.020 seconds. Take the reciprocal of 0.02 which is 50 (Hz), and that's the maximum frequency, as stated by the seller. HTH. **Q: Do you need fan cooling or can you use just a heatsink?** A: Dear customer：A heatsink must be installed for the 100DD. If the working time and current are not large, the fan does not have to be installed. If the time is long and the current is large, a fan must be installed. **Q: What is the activation current in milliamperes for these? Does it change from the 25a to 100a?** A: Dear customer：For DD type solid state relays.Control voltage is 3-32VDC, activation current is 5-25mA. The greater the voltage, the greater the current, and the maximum will not exceed 25MA. **Q: Can i use the ssr-150d x 600vdc to switch 325vdc of pv between two equipment (grid-tie 3kw and water pump 2.2kw)?** A: Sorry.pump is inductive load. can not use ssr. ## Customer Reviews ### ⭐ Review *by M***Z on 4 May 2023* No funciona como un relavador normal energizado o no este se mantiene activado ### ⭐⭐⭐⭐⭐ Review *by J***S on 25 September 2025* Im using one of these 40 amp SSRs to PWM a transmission cooler fan up under my jeep.

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. ## Frequently Bought Together - CG Solid State Relay SSR-25DD DC to DC Input 3-32VDC To Output 5-240VDC 25A Single Phase Plastic Cover - 3.7-12V Wireless Remote Control Switch Mini Small PCB 433mhz RF Transmitter,3V -12V Battery Power Circuit Micro Controller for DIY - 9V Battery Connector,10 PCS T-Type 9 Volt Buckle Connector Hard Plastic Shell Used in Student Experiment,or Other Equipment with Battery --- ## 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.at/products/424741291-cg-solid-state-relay-ssr-25dd-dc-to-dc-input](https://www.desertcart.at/products/424741291-cg-solid-state-relay-ssr-25dd-dc-to-dc-input) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-04-26*
