A digitalizing power supply control board woking with modified ZXD2400 (50V 50A) modoule.
This project is a control board mainly using ESP32 as core MPU, with ST7789V display, including software source codes, hardware design, and other parts design, to control a simply modified ZXD2400 power supply module.
In fact, this project is suitable for modifying other power supply module too.
its main functions include: . 0-50.00V and 0-50.00A output with internal 14bits resolution . Multi-points calibration of voltage and current. . Two EC11 rotaries to control voltage and current separately . Multi quick-pick of voltage and current by single pressing button . Statistics by seconds, minutes, hours . WIFI STA and AP support with a simple web view for remote control . Command line support with USB-Serial interface (also firmware updating interface) . Temperature controlled FAN output using PID algorithm . A discharging circuit to decrease dormancy of switching power supply at low-voltage outputing . Rate of rising and falling of voltage and current can be controlled . Chinese and English bundles support (but in fact, original ZXD2400 with its PFC circiut can be used in AC220V zones)
