Power supply schematics
« on: December 15, 2023, 03:42:41 pm »
Hi all, small question about power supplies. In 2019 I ordered this linear power supply (https://www.komerci.de/shop/stromversorgung/Labornetzgeraete/trafo/qj3005eiii-labornetzgeraet-3-fach-2x30v-5a-regelbar-5v-3a-fest). As an electronics engineer I try to keep documentation of all equipment on my bench, just in case I will have to repair it. On the internet I find this power supply sold under many brand names. Has anyone happened to find the schematics or service manual of this power supply? Would be nice to have it!

Thnks! Slightly different power supply, has LCD instead of LED display and adjustable OCP via up/down buttons (digital) instead of potentiometer
