The description of this device does mention that at 60V the maximum available current is 5A but it is worth pointing out here. Whilst there are other cheaper models that will provide 5A at 60V, I couldn't determine whether those models would provide 10A up to 30V or not as this unit does. Comparing voltages to my inexpensive multimeter shows the output voltages to be exactly the same. The set voltage compared to the actual output can differ by a few hundredths of a volt however. I haven't been able to measure the output current as my multi-meter is not capable of doing so. As others have mentioned, the display for actually setting the output voltage and current is quite small, not the easiest to use for those of us without perfect eyesight. This could have been better as the unit does have a nice large display screen. You can switch the display from graphing mode to numbers only, but the output settings remain the same size. You can change the output by one hundredth, a tenth, a whole, or multiples of 10. If, for example, you select the hundredths unit, you can dial all the way from 0.01V all the way to 60.00V, that would of course take 6000 clicks of the knob. Each press of the V or I button scrolls through each unit in turn. The OVP and OCP work the same way to set over-volt and over-current protection which terminates the output completely if those values are reached. I haven't heard the unit make any noise, but it is quite cold in my garage and I have only used it up to around 30V 2A up until now. I was a little dissapointed that there were no cables included for actually using the power supply, but it is not stated that they are included. Just something to be aware of. Seems like a nice piece of kit with decent build quality. Can't comment on longevity yet though. 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 | |---------------|-------| | ASIN | B0C2CQB7KK | | Best Sellers Rank | 8,911 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 19 in Industrial Power Supply | | Brand Name | OWON | | Compatible Devices | Personal Computer | | Connector Types | DC plug | | Cooling Method | Air | | Country of Origin | China | | Current Rating | 5 Amps | | Customer Reviews | 4.2 4.2 out of 5 stars (71) | | Item Dimensions | 22.6 x 8.2 x 14.2 centimetres | | Item Weight | 1.5 Kilograms | | Manufacturer | OWON | | Manufacturer Part Number | P-SPE3051 | | Maximum Input Voltage | 240 Volts (AC) | | Minimum Input Voltage | 230 Volts (AC) | | Model Name | SPE3051 | | Model Number | OWON-SPE3051 | | Output Wattage | 150 Watts | | System Bus Connector Type | DC Plug (Barrel Jack or Banana Plug) | | Wattage | 150 watts | ## Product Details - **Brand:** OWON - **Compatible devices:** Personal Computer - **Connector type:** DC plug - **Cooling method:** Air - **Current rating:** 5 Amps - **Item dimensions L x W x H:** 22.6 x 8.2 x 14.2 centimetres - **Item weight:** 1.5 Kilograms - **Model name:** SPE3051 - **Output wattage:** 150 Watts - **Wattage:** 150 watts ## Images ![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 - Image 1](https://m.media-amazon.com/images/I/71OghGryxAL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice power supply *by J***7 on 19 January 2026* This review for the SPE6103 60V 10A model.

Digital control dial is quite easy to use. *by G***L on 1 January 2025* 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) ## 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.fr/products/541170757-owon-spe3051-programmable-dc-power-supply-150w-30v-5a-high](https://www.desertcart.fr/products/541170757-owon-spe3051-programmable-dc-power-supply-150w-30v-5a-high) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-08-30*
