Review: Excellent little power supply - Great power supply and does exactly what I need, be aware it doesn’t contain any leads I already have a load of them but just bear that in mind. If you haven’t used a bench power supply before do a bit of research on YouTube etc the instruction manual is good but very concise. All in all very happy with it. ## Features - Programmable digital control — Fine resolution of 10 mV / 1 mA for precise voltage and current adjustments. - Low noise and ripple — Ensures stable, clean output suitable for sensitive electronics and test environments. - CV / CC operating modes — Supports constant voltage and constant current regulation. - Advanced protection features — Includes OVP (over‑voltage), OCP (over‑current) and constant protection mode. - Remote monitoring & control — RS232 and USB interfaces enable PC‑based automation and data logging. - Memory storage — Save and recall up to 5 parameter sets for quick test setup. - Output switch control — Safely enable or disable output without altering settings. - Power‑off memory — Retains last settings after shutdown. - Keyboard lock — Prevents accidental parameter changes. - Supplied with UK Type‑G and Euro Type‑E/F (Schuko) power cords — Ready for international use. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B083BWBC4B | | Best Sellers Rank | 81,257 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 397 in Industrial Power Supply | | Box Contents | 1 x Industrial Power Supply | | Brand Name | TENMA | | Compatible Devices | Power Tools | | Connector Quantity | 1 | | Connector Types | Molex | | Cooling Method | Air | | Country of Origin | China | | Current Rating | 5 Amps | | Customer Reviews | 4.8 4.8 out of 5 stars (6) | | Form Factor | Standalone | | Manufacturer | MULTICOMP PRO | | Manufacturer Part Number | 72-2540 | | Maximum Input Voltage | 45 Volts (DC) | | Minimum Input Voltage | 22.5 Volts (DC) | | Model Name | 72-2540 | | Model Number | 72-2540 | | Output Wattage | 150 Watts | | Power Supply Design | External | | Unit Count | 1.0 count | | Wattage | 150 watts | ## Product Details - **Brand:** TENMA - **Compatible devices:** Power Tools - **Connector type:** Molex - **Cooling method:** Air - **Form factor:** Standalone - **Model name:** 72-2540 - **Number of connectors:** 1 - **Output wattage:** 150 Watts - **Power supply design:** External - **Wattage:** 150 watts ## Images ![MULTICOMP PRO 72‑2540 – Programmable DC Bench Power Supply, 30 V / 5 A - Image 1](https://m.media-amazon.com/images/I/512YAkLvtdL.jpg) ![MULTICOMP PRO 72‑2540 – Programmable DC Bench Power Supply, 30 V / 5 A - Image 2](https://m.media-amazon.com/images/I/61exgxCawBL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐ Excellent little power supply *by D***S on 25 June 2022* Great power supply and does exactly what I need, be aware it doesn’t contain any leads I already have a load of them but just bear that in mind.
