### ⭐⭐⭐⭐⭐ Electronics Bench 0-120V DC PSU - Perfik for Electronic Lab R&D projects
*by D***. on 24 April 2023*

As an Electronics Engineer, I have accumulated a vast range of test equipment over the years. However, with new STEM Solar Energy Monitoring IoT boards, which I am designing, it is sometimes required to replicate a Solar Panel string, using a controlled variable DC supply in the lab. For this a ~40 to 120V DC power supply is required. Purchased this adjustable 0-120V DC Power Supply and upon its fast next day delivery, it has been pressed into service. Works very well. Output is accurate and easy to change voltage and current limits. More importantly, the power supply has a mains ON/OFF plus a DC Output On/OFF. So you can easily set the required voltage and just turn on the output when needed. This is a safety must for High Voltage DC supplies and good to see this on the PSU. Have checked the DC output on the scope, put on a Solar Invertor and also into a DC-DC SMPS and it works perfectly - clean enough for my lab testing. Would recommend, if you need a high voltage DC power supply for some projects. You just need to ensure you have the right voltage set BEFORE turning the DC output on! ** IMPORTANT. 75-120V DC is Dangerous and can cause Electric Shock and Muscular Inhibition! Please RESPECT this Power Supply Output and be careful!! **
