I run a small company and we cannot afford top of the line equipment and we do not require government calibrated units. My company works on electronic and software designs and I have not only used this unit extensively I have also taken the cover off and looked at the internal design, not because there was an issue, but to compare it to a similar looking unit that had a very bad design which failed hence needing to purchase this replacement.We use these PSUs to power small dc devices that we need to test at a specific voltage and current. In most cases we are running at fairly high percentage current draws of 3-4Amps and switching the equipment on and off repeatedly throughout the day. Although we always ramp the voltage up before turning it on and down before turning it off, the unit gets a lot of use perhaps 20 -30 cycles a day.To date the unit has proved reliable and although the heatsink gets warm, there is nothing cooking under the hood and the unit reliably and consistently delivers the set voltage and current required for the tests. Inside the unit is professionally manufactured with a well thought out layout, good circuit design and professional component soldering and connections unlike some other similar units on the market.Overall I am very pleased with this PSU, consider it good value for money and would recommend it to others. ### ⭐ Dead on arrival *by B***K on June 17, 2014* The current limiting LED is permanently on and in fact no power is delivered. We checked the fuses but spending any more time on it than that would cost more than it's worth. I ordered two identical units. The second works but the current display goes in and out for long periods. When it's out it's back-lit but there is nothing displayed on it. ### ⭐⭐⭐ Good value but don't expect 5 amps continuous output... *by B***1 on July 9, 2014* I purchased this power supply as a general purpose bench test supply. It's not bad for the money. It does a decent job of regulating. The displays are big and bright. (My LCD's light up with white LED's backlights.) The Volt meter is OK considering they are only accurate to +/- .1 volt. I would not expect the current to be terribly accurate. But it does a decent job of letting you know approximately what voltage and current is going out. (Probably better than most analog meters.)I put a 24 volt DC blower on the supply and ran it at 24 VDC at about 1.95 amps for 30 minutes. The unit gets pretty warm. I could smell the "new electronics smell" burning off inside. The heat sink on the back got up to the point I could not keep my hand on it. Not sure I would attempt to pull 5 amps continuous out of this power supply. Like most generic Chinese electronic devices you should expect about HALF of the rated specifications... I think it would be OK for 2.5 amps continuous... Not 5. But that it to be expected for a "bargain" linear power supply.Overall this is a nice quiet compact bench power supply. Just don't over load it. --- ## 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.ae/products/1637132-electronix-express-sp-1305d-single-output-linear-dc-power-supply](https://www.desertcart.ae/products/1637132-electronix-express-sp-1305d-single-output-linear-dc-power-supply) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-06-04*
