koradctl - Power Supply Control Utility and Library

koradctl is a simple python library to support the control and automation of Korad KAxxxxP series power supplies. These supplies are also rebadged as other brands including Tenma and Vellerman (see here for a more complete list).

koradctl has been tested with bench power supplies that respond with the following firmware identification. Please let me know if you have successfully used koradctl with other power supplies.

• TENMA 72-2540 V2.1

Install

pip install koradctl

Usage

# Output off
koradctl -e off

# Toggle the output
koradctl -e toggle

# 12v, 400mA, Output on, Monitor with readings once every 10 seconds
koradctl -v 12 -i 0.4 -e on -M -f 10

# 3.3v, 250mA, OCP on, OVP off, Output on, Monitor once
koradctl --ocp on --ovp off -v 3.3 -i 0.25 -e on -m

# 5v, 150mA, Output on, Monitor with default interval, Turn output off on ^C
koradctl -v 5 -i 0.15 -e on -M -o
