# `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](https://sigrok.org/wiki/Korad_KAxxxxP_series) 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

```bash
pip install koradctl
```

## Usage

```bash
# 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

# further usage information:
koradctl --help
```
