Review: Great power supply, well built - Great product and was as expected Review: NICE PSU WITH HARD WEARING CASE AND WELL VENTILATED - CONTAINS LOW COST 12V-10A-120W PSU MODULE - I was looking forward to receiving this and I am quite happy with the heavy-duty case with plenty of ventilation and is also fanless for a silent operation. I wanted a high quality PSU and so I paid £59.90 with Prime next day delivery. PLEASE NOTE: DO NOT OPEN THE UNIT UNLESS YOU ARE COMPETENT AT WORKING WITH DANGEROUS HIGH VOLTAGES WHICH COULD STILL BE PRESENT EVEN IF THE UNIT IS POWERED DOWN. I opened the case as I was curious to see what value for money I had got and found it contains a regular 12V-10A-120W PSU module (the type with the 7 screw terminals) which you can purchase a similar/same module from a well known online auction site for as little as £8.69 including postage direct from Shen Zhen, China! You are basically purchasing the 12V-10A-120W PSU module with the top cover removed (see photos) fitted into a steel case with illuminated power switch, connection terminals, fuse holder and a 1 metre mains power cord with a fitted 3 pin plug which to be fair is safer and convenient but the high price? I will be keeping mine as I urgently need it for a project and on the plus side if it ever breaks down in the future I would just be able to swap out the low-cost PSU module within as it is only connected via screw terminals so I have just bought this for the case basically. ## Features - 1) Converts 240VAC in 13,8VDC stabilized. - 2) The transformer is equipped with a 240V input jack and a 12V output jack. - 3) Deliver a steady supply of 13.8 volts (equivalent full load of a battery) - 4) Its low ripple voltage makes it ideal for any application plug 12 Volt that not exceed 10 amps. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01N0J411W | | Brand | US-TRONIC | | Current Rating | 10 Amps | | Customer Reviews | 4.2 4.2 out of 5 stars (6) | | Manufacturer | ADAPTOO | | Manufacturer Part Number | PSU-12-10A-UK | | Mounting Type | Plug Mount | | Power Source | Battery Powered | ## Product Details - **Brand:** US-TRONIC - **Current rating:** 10 Amps - **Manufacturer:** ADAPTOO - **Mounting type:** Plug Mount - **Power source:** Battery Powered ## Images ![AC-DC step-down transformer from 240 volts to 12 volts 10 amps US-TRONIC - Image 1](https://m.media-amazon.com/images/I/41x+5mhPj1L.jpg) ![AC-DC step-down transformer from 240 volts to 12 volts 10 amps US-TRONIC - Image 2](https://m.media-amazon.com/images/I/41fiNqk38LL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great power supply, well built *by C***D on 27 November 2019* Great product and was as expected ### ⭐⭐⭐ NICE PSU WITH HARD WEARING CASE AND WELL VENTILATED - CONTAINS LOW COST 12V-10A-120W PSU MODULE *by O***Y on 15 March 2020* I was looking forward to receiving this and I am quite happy with the heavy-duty case with plenty of ventilation and is also fanless for a silent operation.
