First preview of the M2 firmware where various input methods are implemented. Thanks to that touch screen become a valid substitute for potentiometer, incremental encoder or numeric keypad. In total five more of operation is possible:

|
| The EEZ power supply is using Arduino for programming and monitoring. Therefore its firmware can be partially tested when uploaded on Mega2560 or Due board without having power supply completed. This video contains required steps for upload to the Mega board and test remote control capability based on SCPI commands. | ||

|
| EEZ PSU firmware can be run and evaluate even without having real device on hand. We are developed software simulator that can be run on all major platforms and can be used for presentations but also for development. | ||
| Firmware M2 in addition to the SCPI remote control comes with support for local control via TFT color touchscreen display. This video shows what functionality is covered in this release candidate version. | ||
The EEZ PSU H24005 channel’s output values can be presented in three different ways:

EEZ PSU H24005 protection mechanisms:
|
||
| EEZ PSU H24005 voltage and current calibration using Calibration wizard | ||
| EEZ PSU H24005 remote control using SCPI commands send via serial (USB) or Ethernet. Establishing connection with SCPI controller application (Keysight Connection Expert) is also demonstrated. | ||
| The tracking mode of operation allows one to set output values, states and protections on the both channel by programming just one of them. That could speed up programming and reduce a chance to make mistake when e.g. symmetrical output is needed (on channel is used as positive and another as negative rail) that programmed values is not equal. | ||
| The EEZ H24005 has two isolated channels, the outputs of which can be combined to get higher voltage (up to 80 V) or current (up to 10 A), within the overall power limit of 310 W. Unlike many other power supplies that allow such channel coupling, with the EEZ H24005 you don’t need to pay special attention to wiring thanks to built-in power relays for both voltage and current coupling. This decreases the risk of damaging the power supply due to a tiny wiring mistake. | ||
Presentation of the following system protection mechanisms:

| See how to use external analog signal for controlling voltage output. | ||
| YT mode allows one to directly monitor on the TFT display what is happening over a long period of time with output voltage, current, or power without the assistance of a PC or other external device. | ||

First preview of added incremental encoder that can be used for selecting and setting output values. | |
| Remote voltage sensing can be used to delivery exact voltage to the load regardless of the voltage drop on the connecting cables caused by current flow. | ||
| First preview of EEZ Studio, a visual toolkit we developed and used for the EEZ H24005 to create the TFT touch-screen display GUI. | ||
| Trigger system and list programming – Part 1 of 2 shows how is possible to trigger a change of output values using one of four trigger sources.
|
||
| Trigger system and list programming – Part 2 of 2 shows how is possible to program outputs using list of up to 256 different voltage and current values. | ||
| Using of foot pedal to control outputs. | ||
| Preview of two main features added to firmware v1.1: SD card file management and internal data logging using SCPI commands.
The EEZ Studio version M1 (its ESW module) is used for interaction with the EEZ H24005 (i.e. initiate data logging and exchange files). |
