Review: Great Rectifier - Rectifier works great. Good price and fast shipping. Happy with purchase. Review: WORKING WELL FOR THE PROJECT - This rectifier was used on a drum sander that was made using the motor and roller from a treadmill. So far I have gotten very good results using this to recify current from an SCR voltage controller to power the DC motor. ## Features - 【High Power Rectification】 Rated for a maximum output current of 100A and a repetitive peak reverse voltage of 1200V, this QL100A bridge rectifier is engineered to handle high-power industrial electrical loads with stable performance - 【Efficient AC to DC Conversion】 Seamlessly convert single-phase alternating current (AC) input into direct current (DC) output. Ideal for power supplies, motor controls, and battery charging systems requiring reliable rectification - 【Integrated Heatsink Design】 Features a robust metal housing with an integrated aluminum heatsink for superior heat dissipation. This design prevents overheating during continuous operation, significantly extending the service life of the diode bridge - 【Secure & Easy Installation】 Designed with four sturdy terminals and pre-drilled 7mm fixing holes (45mm spacing), ensuring a secure flush mount on racks or panels for vibration-resistant industrial applications - 【Strict Wiring Safety】 For safe and reliable operation, please ensure the DC output and AC input are wired strictly according to the polarity markings (+, -, ~) as shown in the product images to prevent circuit damage ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.4 out of 5 stars 120 Reviews | ## Images ![Baomain 100A Amp 1200V Volt Diode Bridge Rectifier Metal QL100A - Image 1](https://m.media-amazon.com/images/I/61-DWrQ+R5L.jpg) ![Baomain 100A Amp 1200V Volt Diode Bridge Rectifier Metal QL100A - Image 2](https://m.media-amazon.com/images/I/61gZNZoXt9L.jpg) ![Baomain 100A Amp 1200V Volt Diode Bridge Rectifier Metal QL100A - Image 3](https://m.media-amazon.com/images/I/61KAQksNTML.jpg) ![Baomain 100A Amp 1200V Volt Diode Bridge Rectifier Metal QL100A - Image 4](https://m.media-amazon.com/images/I/51puRiFJBhL.jpg) ![Baomain 100A Amp 1200V Volt Diode Bridge Rectifier Metal QL100A - Image 5](https://m.media-amazon.com/images/I/61C-3W1ZfFL.jpg) ## Questions & Answers **Q: What capesitor did tou use** A: I used two 30000mfd in my welder. Works great. Hope this helps you our. **Q: Does it have mounting bolt slots?** A: Hello Sarah, it does have 2 mounting holes, they are at the top and bottom of the bridge rectifier. The mounting holes are inside the heat sink fins, so they cannot be seen from the picture. The holes are 13/64'' in diameter (according to calipers), so #10 (3/16) bolt would fit. There is very little room for a washer, although you may be able to fit a small one. **Q: can i use this in 12v automotive applications?** A: I used it to convert a wire welder to DC. But I would think you could. Have no idea where you would want to use it... **Q: does this rectifier turn ac to dc voltage** A: Yes ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Rectifier *by R***. on September 19, 2024* Rectifier works great. Good price and fast shipping. Happy with purchase. ### ⭐⭐⭐⭐⭐ WORKING WELL FOR THE PROJECT *by S***. on March 28, 2024* This rectifier was used on a drum sander that was made using the motor and roller from a treadmill.

I thought I fried mine a couple of times but survived. Getting terminals lead connected is difficult. Soldering requires a torch and heat sink. Daze Cars utube channel has good technique. ## Frequently Bought Together - Baomain 100A Amp 1200V Volt Diode Bridge Rectifier Metal QL100A - Yeeco AC 110V 10000W SCR Electronic Voltage Regulator Motor Speed Control Thermostat Governing Governor dimmer - smseace 20Amp Electric Button Breaker 125/250VAC,Thermal Overload Protector L1 Series with Manual Reset, Waterproof Button Cap L1-20A --- ## 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.com.om/products/6360781-baomain-100a-amp-1200v-volt-diode-bridge-rectifier-metal-ql100a](https://www.desertcart.com.om/products/6360781-baomain-100a-amp-1200v-volt-diode-bridge-rectifier-metal-ql100a) --- *Product available on Desertcart Oman* *Store origin: OM* *Last updated: 2026-05-25*
