I needed a way to make sure no more than 12 volts went to the energizer. The place we bought this from had a couple of diodes in the circuit that were being used solely for their voltage drop to get the voltage from the battery down to 12 volts. That seemed hacky to me and was unreliable. I connected the input of this voltage regulator to the load output of my solar controller then connected the output of the voltage regulator to the input of the fence energizer (well actually through an on/off switch first but conceptually the same). The energizer is quite happy with the 12 volts this regulator is putting out. I have only had it for a few days so can't speak to its longevity but so far so good. ## Features - DC 24V Down to DC 12V: Input Voltage: 24V nominal, Input Current: 20A (max) ; Output Voltage: DC 12V 20A 240W - 95% conversion efficiency: Synchronization rectification technology-multiple intelligent protection function with high conversion efficiency and stability.

Works fine ?? I think maybe folks overloaded theirs or have high inrush current. Haven't cooked the 15amp either. This unit shows unloaded 0-.20 watt use. Where the 15 amp uses 1 watt idle. Big help if you're trying to max maximum use of WH when the sun is down. - It's running a ubiquiti LTU lite, and soon to be an LTE radio. --- ## 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.br/products/208143137-12v-240w-dc-dc-converter-voltage-regulator-step-down-24v](https://www.desertcart.com.br/products/208143137-12v-240w-dc-dc-converter-voltage-regulator-step-down-24v) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-04-23*
