Title: Hantek PPS2116a reverse engineering
Post by: fqahmad66 on June 02, 2021, 07:03:08 am
My Hantek PPS2116a finally died so took it apart to study and do some reverse engineering. Starting with the power board (usually the culprit), noted that it has AC fault sensing which the Korads lack.

Next Trying to understand the Main Board. Does somebody managed to successfully download the hex file? Never mind.. I got it.

Main Board Layout and schematic. Can somebody educate how is the OVP implemented? Cannot trace it.

Latest destination of this power supply.

There is no programmable OVP...just  a built in AC fault shut down.
