DC power supply 30V 10A*1 User's manual (English)*1 AC power cord (British Standard)*1 DC output cable (alligator clip)*1 Review: Has stood the test of time. - Has stood the test of time. (0-30V 10A Model) I have has this for a while now and works reliably, Its got all of the standard features I need, including constant voltage, constant current and current limit (kills the output when the limit is reached). The encoder style knobs make setting simple and accurate. The voltage measurement is very accurate, but I have found the current reading a bit off, particularly at low values - but its not really an issue as Id always take physical current readings if accuracy was important. I have tested the voltage and current through out the full range, it does get warm when full output, but that's not surprising. Most of the time I use this with less than 1/2 Amp. Seen some comments regarding the mains connector but I have not experienced any issue with this. Mine had a uk fused plug top and the plug amd socket at the rear was very secure.

It'll show up on a 'scope if there's no load, probably as a sequence of quick impulses with a decaying "ring", it's nowhere near as bad as a typical cheap switched PSU and any kind of load capacitance should mop it up. If you mean audible noise, it has a fan but that only comes on when it's hot. Without the fan running it's effectively silent, though some switching PSUs can emit a whistle at the switching frequency, if you get one with something physically able to vibrate inside and your ears are up to hearing that. My ears aren't bad and I've heard nothing from my one. **Q: With ‎wps1203h style ‎120v/3a(360w) what is maximum current at 12v / 24v?** A: At both voltages, the max current is 10 amps. **Q: How do I set constant current for it? It keeps reverting to 0 when i press output** A: Replicated your problem on my unit - once you have set your required voltage output and the maximum current limit setting for the item under test or being run you then push 'Output' .... BUT, if there is no active load attached to the power supply it will show the row of 'zero's' on the current readout after a couple of seconds or so. **Q: When using the usb output is the current and voltage displayed so that you can use it as a usb power meter?** A: NO THERE IS NO VISUAL INDICATION THAT THE USB CIRCUIT IS ON OTHER THAN THE APPLIANCE ON CHARGE THE FRONT PANEL SHOWS ONLY POWER OUTPUT NOT USB. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Has stood the test of time. *by M***Y on 14 September 2025* Has stood the test of time.

I doubt that I will need 300W of power, but always nice to have under the hood for the same price as the 150W PSU. The unit is surprisingly small but well specified and not short on features. The buttons have a reassuring notched click to them when turned, and they also beep, however I quickly turned off the beeping using the system settings menu. The white LED on black display is large and clear and a definite upgrade to the retro red LED displays. As displayed in the photos the unit is very accurate and should be fine for most applications, bearing in mind that slight inaccuracy may be due to test leads having some resistance, and also test meters may also be slightly out of tolerance, unless you are a lab tech using properly calibrated equipment, this should be a welcome addition to your test bench. Inside the unit is neat and tidy, and uses suitable gauged cable and connectors to handle loads upto 10A, with quality components. The fan does not cut in often, but when it does it is reasonably quiet. The USB quick charge port, fast charges the latest Samsung Galaxy S22 phones with no problem, I do not have an iPhone but I guess it will work equally as well. This leads me to my minor grip with the unit, the binding posts are cheap as chips, they are okay I suppose, but not the type that I have been used to. There are no holes in the posts to thread cables through if you are out of banana plugs, or want to link the terminals together, and the black knobs can actually be unscrewed completely from the posts which could lead to them being lost? As someone also posted that one of their binding post snapped off, I decided to swap them out for some others that I found on Amazon 'CDL Micro Binding Terminal Posts', and they are much better quality. And yes I did intend to swap the position of the -ve and +ve posts, just didn't seem right. Also if you are after a pdf version of the manual head over to wanptek.com where you can download a copy. Overall very pleased with the product, it is solidly built, has great functionality, and I got it at a great price, just go easy on the binding posts. ## Frequently Bought Together - DC power supply (0-30V,0-10A) adjustable, switching power supply, mini high precision 4-digit display with USB fast charging interface, variable lab bench power supply, output button/encoder knob - Cleqee 3 Pairs Multimeter Test Leads Set 4mm Stackable Banana Plug to Alligator Clips Mini Test Hook Clips Stackable Banana Plug Cables Copper Electrical Wire - Cleqee Multimeter Test Leads Kit 21PCS Electrical Test Cables with Alligator Clips SMD IC Test Hook Clips Test Tweezer Spade Plug Banana Plug Replaceable Needles Pins --- ## 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.pe/products/370076703-dc-power-supply-0-30v-0-10a-adjustable-switching-power](https://www.desertcart.pe/products/370076703-dc-power-supply-0-30v-0-10a-adjustable-switching-power) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-05-24*
