Also it can be sent via email. The installation is very simple, but must be done by a qualified professional to avoid personal injuries and any equipment damage. **Q: Does this switch work with low voltage applications?** A: I think not **Q: I see that one of the specs says, "Provides external voltage adjustment feature". Can this product be used on low voltage applications (24V)changeover** A: Unfortunately not. Because anyway the device must be powered by 120VAC voltage. **Q: so the two powers must be at a minimum of AC 110 Volts ?** A: This switch can work with power sources having 2-3 phases 120/240VAC where 120VAC (phase-neutral) and 240VAC (phase-phase). --- ## 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.sk/products/60924446-elpro-ats-63a-120-208v-50-60hz-automatic-transfer-changeover](https://www.desertcart.sk/products/60924446-elpro-ats-63a-120-208v-50-60hz-automatic-transfer-changeover) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-05-24*
