Modular programmable bench power supply is based on EEZ H24005 project and introduce new digital control and better modularity by using EEZ DIB backplane based on DIB v1.0 specification that allows adding of new functions in the future (e.g. multi-channel power source, 2/4-quadrant power module, multi-channel temperature sensor module, data logger, switch matrix, digital I/O expander, function generator, data acquisition module, etc.). It is work in progress and it's conceived to have the following components/modules:

  • BP3C EEZ DIB backplane with series/parallel power coupling capability of first two modules
  • AUX power supply board with AC input protection, soft-start/power-up control, DC fan controller and +5 V / +12 V power outputs
  • MCU board based on STM32F769IGT6 32-bit ARM Cortex-M7 as replacement for Arduino Due
  • DCP405, 0 - 40 V / 5 A DC power source, an EEZ H24005 Power module variant (require an off-the-shelf fixed output 48 Vdc AC/DC power module)
  • DCM220, dual sync buck 0 - 20 V / max. 4 A with current limit
  • Bench Box 3 metal enclosure for housing up to 3 modules with 4.3" TFT LCD. Dimensions: 290 (W) x 123 (H) x 240 (D) mm

Please note that some previous board types and revisions that could be still usable in some cases can be found under previous design folder.
