hantekpsu 0.1.3

Python interface for Hantek bench power supply

Hantek Power Supply Controller

This is an interface to the serial port on Hantek HDP1160V4S power supply. It should work with other HDP10000-series power supplies. buy

❗ATTENTION❗

USING THIS CODE MAY DAMAGE YOUR POWER SUPPLY OR CONNECTED DEVICES. USE AT YOUR OWN RISK.

To communicate with the PSU I am using USB-to-RS232 adapter - does not require any drivers on debian linux.

Installation

pip install hantekpsu

Usage

from hantekpsu import PSU
p = PSU(port='/dev/ttyUSB0', baudrate=2400)

Methods

Method	Description	Return Type
turn_on()	Turns on the power supply unit.	None
turn_off()	Turns off the power supply unit.	None
ocp_on()	Enables Over Current Protection (OCP).	None
ocp_off()	Disables Over Current Protection (OCP).	None
ovp_on()	Enables Over Voltage Protection (OVP).	None
ovp_off()	Disables Over Voltage Protection (OVP).	None
get_model()	Gets the model of the PSU.	str
get_active_voltage()	Gets the active output voltage of the PSU in volts.	float
get_active_current()	Gets the active output current of the PSU in milliamps.	int
get_voltage_limit()	Gets the voltage limit setting of the PSU in volts.	float
get_current_limit()	Gets the current limit setting of the PSU in milliamps.	int
get_on_off_status()	Returns the on/off status of the PSU.	bool
set_output_voltage(v: float)	Sets the output voltage of the PSU in volts.	None
set_output_current(mA: int)	Sets the output current of the PSU in milliamps.	None
set_ovp_limit(v: float)	Sets the Over Voltage Protection (OVP) limit in volts.	None
set_ocp_limit(mA: int)	Sets the Over Current Protection (OCP) limit in milliamps.	None

Examples

Set voltage to 12V and turn on the power supply:

>>> from hantekpsu import PSU
>>> p = PSU()
>>> p.set_output_voltage(12.0)
>>> p.turn_on()

Development

Requirements

• python 3.10+
• poetry

Ensure the device is connected. If using usb-to-rs232 adapter, run lsusb:

$ lsusb
Bus 001 Device 012: ID 0403:6001 Future Technology Devices International, Ltd FT232 Serial (UART) IC

You should also see something similar to /dev/ttyUSB0 in the /dev folder.

To figure out which device it is, you can run ls /dev before plugging in the adapter and after and compare the differences.

Installation

git clone https://github.com/builder555/hantek-controller
cd hantek-controller
poetry config virtualenvs.in-project true --local
poetry install

Unit Tests

When adding new features or modifying existing ones, make sure you add unit tests and run them:

$ poetry run pytest -v

You can also run pytest-watch while developing to run tests automatically on save:

poetry run ptw --runner 'pytest -v'
