I would buy again. Do not post bad delivery experiences because Amazon has made that a community standards offense. ### ⭐⭐⭐⭐⭐ Works well *by on Reviewed in the United States 9 June 2024* I have this powering a 12v water temp sensor and display for our pool. It works well and fit nicely on the DIN rail with my other relays. It does produce a high frequency hum when operating but you can’t hear it when the enclosure is shut. ### ⭐⭐⭐⭐⭐ Keeps on working. *by on Reviewed in the United States 12 January 2025* I put this supply into service a couple of years ago and it is still working good, just as it did when it was new. ## Frequently Bought Together - MEAN WELL MDR-20-12 AC to DC DIN-Rail Power Supply 12V 1.67 Amp 20W - MEAN WELL MDR-20-5 AC to DC DIN-Rail Power Supply 5V 3 Amp 15W - MEAN WELL MDR-20-24 AC to DC DIN-Rail Power Supply, 24V, 1 Amp, 24W, 1.5" - 1943385 --- ## 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.sn/products/331290659-meanwell-mean-well-mdr-20-12-mdr-20-series-20](https://www.desertcart.sn/products/331290659-meanwell-mean-well-mdr-20-12-mdr-20-series-20) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-11-15*
