Owon SPEx103 PSU python control library

This library works with the Owon SPE6103 and SPE3103 power supplies. Kiprim devices "DC310S" and "DC605S" are also supported.

Installation

The easiest way to install is straight from the pypi project using pip:

pip install owon-psu

Example Usage with context manager

from owon_psu import OwonPSU

with OwonPSU("/dev/ttyUSB0") as opsu:
  print("Identity:", opsu.read_identity())
  print("Measured Voltage:", opsu.measure_voltage())
  print("Measured Current:", opsu.measure_current())

  print("Set Voltage:", opsu.get_voltage())
  print("Set Current:", opsu.get_current())

  print("Set Voltage Limit:", opsu.get_voltage_limit())
  print("Set Current Limit:", opsu.get_current_limit())

  opsu.set_voltage(20)
  opsu.set_current(2)
  opsu.set_voltage_limit(30)
  opsu.set_current_limit(3)

  print("Output enabled:", opsu.get_output())
  opsu.set_output(True)

Example Usage without context manager

from owon_psu import OwonPSU

opsu = OwonPSU("/dev/ttyUSB0")
print("Identity:", opsu.read_identity())
print("Voltage:", opsu.measure_voltage())
print("Current:", opsu.measure_current())

print("Set Voltage:", opsu.get_voltage())
print("Set Current:", opsu.get_current())

print("Set Voltage Limit:", opsu.get_voltage_limit())
print("Set Current Limit:", opsu.get_current_limit())

opsu.set_voltage(20)
opsu.set_current(2)
opsu.set_voltage_limit(30)
opsu.set_current_limit(3)
print("Output enabled:", opsu.get_output())
opsu.set_output(True)
