Control utility for Korad / Tenma power supplies

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
