Lo cierto es que la intensidad que admite son 33 A, que son unos 400W de potencia ... ahí es ná En este caso está mejor pensada la estructura dado la arquitectura empleada con metal enrejillado para que circule mejor el aire y no se caliente tanto. La ventaja en este caso no es tanto la fuente como la posibilidad de regular los 12 V y conseguir aumentar o disminuir el brillo de las tiras led o lo que le pongamos En resumen, una fuente bien construida y muy potente ## Frequently Bought Together - LED Driver 12V 400W 33.3A LED Transformer IP20 AC 220V to DC 12 Volt Constant Voltage Slim Switching Power Supply for LED Strip Lights LED Bulbs and Indoor Lamps - BRIMETI 24V LED Driver 200W LED Transformer AC 240V to DC 24 Volt 8.3A Ultra Slim LED Power Supply Constant Low Voltage Switching, Adapter for LED Strip Light Cabinet Lights - DUSKTEC LED Driver 24V 300W LED Transformer, Slim LED Power Supply 12.5A Adapter AC 240V to 24V DC, Constant Voltage for LED Strip Cabinet Lights G4 MR11 MR16 LED Light Bulbs --- ## 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.pl/products/542533004-12v-400w-led-power-supply](https://www.desertcart.pl/products/542533004-12v-400w-led-power-supply) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-27*
