Feature: 1. All are in-line components, easy to install and maintain, the output voltage is easy to adjust. 2. The output current limit status is indicated by LED, when the output current exceeds the limit current, it will automatically switch to constant current mode to provide full protection against overload or fault. 3. DIY parts set, need to install by yourself, can exercise hands-on ability. 4. High quality DC regulated power supply whose output voltage is continuously adjustable from 0 to 30V. 5. Provide current limiting, LED display, over load and short circuit protection.
