Although it is rated for 110v input, inside the supply, if you feel comfortable with taking the cover off, there is a toggle witch will allow 220v input. They do this because it is easier to modify for other countries. It's older technology because it is not adaptive but how often would you change input. I do recommend taking off the cover and inspecting it. Mine came with the transformer not tightened down and some balls of lose solder bouncing around. Do inspect it before use but I have to say, it has been a pretty solid performing unit despite the poor assembly/final inspection. **Q: How to increase brightness of dispay?** A: No problem with the brightness of the display as of a new purchase November 2020. **Q: What's the weight of the power supply ? Is it heavy?** A: This bench power supply 60v 5A comes with compact design and light weight , the host no less than 1.5kg. **Q: Can it be used for electrolysis?** A: It provides up to 30 volts at 10 amps continuously so it can replace a battery from 1volt to 30 volts and deliver up to 10 amps of current. If this would meet the power requirements of the electrolysis equipment then you are good. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Made My Life Easier *by A***R on May 24, 2025* This Power supply works great!

Small size so you do not need large space. Easy to use it. Like it. ### ⭐⭐⭐⭐⭐ Works, numbers light up niceu *by A***S on February 11, 2024* Purchased this to anodize aluminum in the .58 square foot size using the low current density method. Also successfully used it for etching aluminum. Works well for constant current. Numbers were easy to read, and no overheating problems with 2 hour runs. I didn’t test it for accuracy against a multi-meter. It has no hum. Nice small profile. ## Frequently Bought Together - 60V 5A Bench Power Supply Variable Precision Adjustable Regulated Power Supply 4-Bit LED Display for Lab Equipment, DIY Tool, Repair, Electronic Research, Powering E-Bike - Elenco Electronics TL-16 Banana to Large Alligator Test Lead Set - Elenco TL-12 Banana to Mingrabber Set --- ## 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.co.uk/products/100821567-30v-5a-dc-bench-power-supply-variable-3-digital-led](https://www.desertcart.co.uk/products/100821567-30v-5a-dc-bench-power-supply-variable-3-digital-led) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-16*
