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. ## 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.dk/products/370076703-dc-power-supply-0-30v-0-10a-adjustable-switching-power](https://www.desertcart.dk/products/370076703-dc-power-supply-0-30v-0-10a-adjustable-switching-power) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-06-01*
