Bought two of the HanmaTek HM610P switching power supply to replace my discommissioned decades old one, happy with it features in general. Especially it came with software that can control it through USB interface on Windows, but the software does not do what I wanted.

Later found out this HanmaTek power supply actually is from eTOMMENS, a China power supply manufactor, wher it model is eTM-3010P, now some of the information found from the application's setting XML file start making senses. http://www.etommens.com/products_content-2023956.html.

What I want are: ontrol it voltage, current, over current protect, able to turn on/off with varies of presets for specific project or boards. That software just does not do a good job for me.

With documents on its CD I found that it use MODBUS protocol on serial (FTDI-USB), and some setting found in the applicaiton setting XML files I was able to found some userful register address that is useful to control it.

That encourage me to develop this program to control the power supply, I can now run a batch file to set varies of power parameters for my own project. I also hope other owner of this power supply may found it userful, or get source code enhance it or just change it to meet your specific need.

Source code it in https://github.com/mckenm/HanmaTekPSUCmd

You can download the release version of code and binary from https://github.com/mckenm/HanmaTekPSUCmd/releases

Hope you will found some use of it!

This simple program is writtern in C#, and depends on CommandLine and System.IO.Port.

To use it just unzip the compiled binary and run the hmps-cmd.

Program syntax is:

hmps-cmd Port/Alias [options]

You can put multiple options to it command line, if same options only will use the first one. Say if you like to set V=5, A=1.1, OCP=1, then you can do the following:

hmps-cmd COM5 --SetV 5 --SetA 1.1 --SetOCP 1

You can set default port by edit the file hmps-cmd.exe.config:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.7.2" />
    </startup>
  <appSettings>
    <add key="Default" value="COM6" />
    <add key="PSU1" value="COM6" />
    <add key="PSU2" value="COM7" />
  </appSettings>
</configuration>

Just update the Default's value from COM6 to match your enviornment. To use the default, just do the following:

hmps-cmd --SetV 5 --SetA 1.1 --SetOCP 1

Or if you want to set alias for your port, the "PSU1" and "PSU2" you can change that to something you like and matching the port on your system. You can add additional alias (key) to this file, just follow the same format.

To use alisa with the above example to PSU2 that set to COM7, just do the following:

hmps-cmd PSU2 --SetV 5 --SetA 1.1 --SetOCP 1
