Wide range voltage Adjustable and output stable DC power supply with two adjustment methods: high-precision knob and directional key. 3 sets of quick parameter storage keys: can preset the voltage and current values when the output is turned off, and can quickly call up the pre stored values of 1/2/3, making it convenient and flexible. It has four protection functions: overvoltage protection (OVP), overcurrent protection (OCP), over temperature protection (OTP), and overload protection (OPP). Front 5V2AUSB charging interface. One click output on/off, one click voltage and current stabilizing switch, automatic locking menu key to prevent incorrect operation. TFT color screen LCD 4-bit display, 360 ° full view view. The panel can simultaneously display the output status, output current, voltage, power, and display time, as well as the switch status of overvoltage protection (OVP)/overcurrent protection (OCP). Can support global voltage adjustment: 110V/220V. Specifications: Output voltage: 0-40V, output current: 0-20A Resolution: 10mV (≤ 0.1%+5 digits); 10mA(≤0.1%+10digits ) Ripple: ≤ 12mVrms, ≤ 18mArms Load/power regulation rate: ≤ 0.2% Vmax+5mV Working voltage: AC220V ± 10% 50Hz or AC110V ± 10% 60Hz Max voltage: 40.5V Max current: 20.1A OVP: 0-41V OCP: 0-20.5A output power: 0-300W Size: 230 * 80 * 150mm Weight: 1.68kg Packaging content: DC output power supply power cord Instruction manual Test line USB connection cable ## Features - Programmable: Variable DC power supply with USB-B connection port on the back for fast and accurate voltage/current adjustments, setting multiple memory values, exporting data tables/graphs via PC; with hardware list, with programmable sequence outputs and more. - Wide Range Power Supply: This programmable power supply can output up to 40V voltage 20A current, compared with other 300W power supplies, it has a wider output range, which is multi-purpose, energy-saving, scalable and wide range. It perfectly replaces various specifications in the market, for example, it can output 30V5A, 30V10A, 15V20A and so on. You can dynamically adjust the voltage and current according to your needs. - TFT screen with Multi-function display: Full viewing angle, high precision 4-digit display for voltage (output voltage set value and actual output value), current (output current set value and actual output value), actual output power, totalized execution time, channel output status, OCP/OVP switching status. The data is very intuitive and easy to understand. - Precision encoder knob and direction key: Unlike other DC power supplies this adjustable power supply can be adjusted using two ways: high precision knob and direction key, which can meet different usage habits, support coarse and fine adjustment, and can set the required voltage or current more precisely. Make your work more flexible and efficient. - Memory storage, key: Bench DC power supply with 3 sets of data storage buttons, 1, 2, 3, you can set the commonly used data for storage as a shortcut parameter, and then turn on the DC power supply can be used again with one key, very convenient. With menu button, with up and down buttons can set U/I shortcut parameters. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DFYGFDMJ | | Best Sellers Rank | #458,514 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #723 in Lab Power Supplies #1,132 in Life Science Supplies | | Brand | MAXRIENY | | Built-In Media | DC power supply,power cord,Instruction manual,Test line,USB connection cable | | Compatible Devices | Personal Computer | | Connector Quantity | 1 | | Connector Type | usb | | Connector Type Used on Cable | usb | | Cooling Method | Air | | Current Rating | 20 A | | Customer Reviews | 4.3 out of 5 stars 6 Reviews | | Form Factor | Bench | | Item Dimensions | 9.06 x 3.15 x 5.91 inches | | Item Weight | 1.68 kg | | Manufacturer | BSIDE | | Maximum Input Voltage | 242 volts_of_alternating_current | | Mfr Part Number | Programmable DC Power Supply | | Minimum Input Voltage | 110 volts_of_alternating_current | | Model Name | I8 DC power supply 40V20A | | Model Number | I8 DC power supply 40V20A | | Number of Fans | 1 | | Number of Items | 1 | | Output Wattage | 300 watts | | System Bus Connector Type | USB-B | | Wattage | 300 watts | ## Product Details - **Brand:** MAXRIENY - **Compatible Devices:** Personal Computer - **Connector Type:** usb - **Cooling Method:** Air - **Form Factor:** Bench - **Item Weight:** 1.68 Kilograms - **Item dimensions L x W x H:** 9.06 x 3.15 x 5.91 inches - **Model Name:** I8 DC power supply 40V20A - **Output Wattage:** 300 Watts - **Wattage:** 300 watts ## Images ![BSIDE Programmable DC Power Supply 40V 20A Bench Power Supply Small Variable Lab Power Supply Adjustable Switching Regulated Wide Range Power Supply with Button and Knob Adjustment, Memory Function - Image 1](https://m.media-amazon.com/images/I/61I6Hwfk53L.jpg) ![BSIDE Programmable DC Power Supply 40V 20A Bench Power Supply Small Variable Lab Power Supply Adjustable Switching Regulated Wide Range Power Supply with Button and Knob Adjustment, Memory Function - Image 2](https://m.media-amazon.com/images/I/71UjGQaEa6L.jpg) ![BSIDE Programmable DC Power Supply 40V 20A Bench Power Supply Small Variable Lab Power Supply Adjustable Switching Regulated Wide Range Power Supply with Button and Knob Adjustment, Memory Function - Image 3](https://m.media-amazon.com/images/I/714VbNTrOoL.jpg) ![BSIDE Programmable DC Power Supply 40V 20A Bench Power Supply Small Variable Lab Power Supply Adjustable Switching Regulated Wide Range Power Supply with Button and Knob Adjustment, Memory Function - Image 4](https://m.media-amazon.com/images/I/71qGO877HCL.jpg) ![BSIDE Programmable DC Power Supply 40V 20A Bench Power Supply Small Variable Lab Power Supply Adjustable Switching Regulated Wide Range Power Supply with Button and Knob Adjustment, Memory Function - Image 5](https://m.media-amazon.com/images/I/718X+JZldOL.jpg) ## Frequently Bought Together - BSIDE Programmable DC Power Supply 40V 20A Bench Power Supply Small Variable Lab Power Supply Adjustable Switching Regulated Wide Range Power Supply with Button and Knob Adjustment, Memory Function - Sumnacon Multimeter Banana Plug to Crocodile Alligator Clip Test Probe, 5PCS 4mm Stackable Colorful Silicone Banana Plug to Alligator Clip Test Probe Lead Wire Cable 1M - Sumnacon 39 Inch Multimeter Test Lead Set - 5 Pcs Stackable Banana Plug to Test Hook Wire Cable Kit with Protective, Flexible Wire Leads for Electrical Testing 500V/5A --- ## 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.no/products/662758810-bside-programmable-dc-power-supply-40v-20a-bench-power-supply](https://www.desertcart.no/products/662758810-bside-programmable-dc-power-supply-40v-20a-bench-power-supply) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-16*
