Digital control dial is quite easy to use. - Great unit - I needed something that went up to 60V and this fitted perfectly. Operation is easier than I thought it would be. I noticed with these digital rotary controls, the volts and amps settings are done digit at a time - ie you press a button to set in 0.1, 1, 10 units (there's a small cursor to show which digit you change) It's not the same as an analogue dial that you just turn from 0 to 11. What I didn't realise was that you can just keep it on the smallest setting and keep turning - i.e. you could leave it on 0.1 and it will move from 0.9 to 1.0 (not 0.0) It kind of works as you hope it would. The V+I graph is the default display which is a bit of a shame, it's generally not very useful versus large digits. However you can see everything on the decent sized screen - both the set V/I and the actual V/I - so it's much better than the cheaper 7-segment LED units. Particularly useful when you're using constant current mode and you can see the live voltage as well as your set maximum. (e.g. when charging a broken lithium battery cell) I can't think of any downside of the unit. It's true that you can't do 60V at 10A (it will be 5A max) - but the unit is clearly labelled 300W only, so it's fair that you are limited by total power (30Vx10A = 300W, 48Vx6.25A = 300W, 60Vx5A = 300W ... you get the picture) Review: Good, compact, DC power supply - Overall I'm very happy with the power supply. Having used 2 DIY power supplies, I built previously, I feel far more confident using the factory one. It is accurate and has all the required protections built in. My only critisism is, when changing the digit/decimal place, on either the volatage or current settings, the highlight cursor is not very visible. This would not stop me purchasing, but I am sure there is a better alternative. ## Features - Multiple Protections: The built-in fan low arc noise & low ripple,The power supply is durable and compact. Productive work since the power supply comes multiple protection of Over-voltage, over-current, over-power, over-temperature, short-circuit powerful protection function. - 5V/1A USB Port: The DC power supply is equipped with a 5V/1A USB port, Rear USB device communication port supporting SCPI,front 5V 1A USB interface can be used to charge mobile phones, tablet or other devices. - Programmable Power Supply: Memory key. You can save 4 sets of channel parameters (M1 to M4) and output them quickly. List waveform output settings: You can edit and get output waveforms, the waveform set contains 10 editable points. The editable parameters for each point include output voltage, output current, waveform duration, and whether the point is selected. - Auto Power Calculation: Intelligently calculates output voltage and current into power and displays the value on its large screen.; decimal point automatic carry & LED 4 digits display of voltage function displays.current and power; The keyboard can be locked to prevent miss operation. - Ultra-thin Body,Portable and Easy to Use: One device is equal to multiple. Bench power supply adopts stable vertical design, DC power supply is very light and portable, with a size of only 3.2*8.9*5.6 inches and a weight of only 3.3 pounds. You can easily take the DC power supply to work. ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | OWON | | Product Dimensions | 22.6 x 8.2 x 14.2 cm; 1.5 kg | | Item model number | OWON-SPE3051 | | Manufacturer | OWON | | Are Batteries Included | No | | Item Weight | 1.5 kg | | Guaranteed software updates until | unknown | ## Product Details - **Brand:** OWON - **Compatible devices:** Personal Computer - **Output wattage:** 150 Watts - **Cooling method:** Air - **Item dimensions L x W x H:** 22.6 x 8.2 x 14.2 centimetres - **Item weight:** 1.5 Kilograms - **Current rating:** 5 Amps - **Manufacturer:** OWON ## Images ![SPE3051 Programmable DC Power Supply, 150W 30V/5A High Precision 4 Digit Multiple Protection,2.8 inch TFT LCD Display with USB Port Support SCPI Laboratory Power Supply - Image 1](https://m.media-amazon.com/images/I/71OghGryxAL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very useful for your tool shed.

Controls take some getting use to, but once target voltage set unit works well. The ability to switch the supply on / off without killing the unit is expected but not present on some other units. Very pleased with this purchase. ## Frequently Bought Together - OWON SPE3051 Programmable DC Power Supply, 150W 30V/5A High Precision 4 Digit Multiple Protection,2.8 inch TFT LCD Display with USB Port Support SCPI Laboratory Power Supply - OWON XDM1041 Protable Bench Multimeter with 3.5 Inch 55,000 Counts True RMS Ultra-light Digital Multi Tester for Labs, Factories --- ## 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.pl/products/541170757-spe3051-programmable-dc-power-supply-150w-30v-5a-high-precision](https://www.desertcart.pl/products/541170757-spe3051-programmable-dc-power-supply-150w-30v-5a-high-precision) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-22*
