TenmaPs(port)

Interface for a Tenma power supply device.

This class manages connection to a Tenma power supply, allowing users to retrieve device status and control voltage/current settings.

Attributes:

Name	Type	Description
VOLTAGE_MULTIPLIER	float	Multiplier to convert volts to millivolts.
CURRENT_MULTIPLIER	float	Multiplier to convert amps to milliamps.

Example

from tenma_ps.power_supply import TenmaPs

with TenmaPs("COM4") as tenma_ps:
    print("Device version:", tenma_ps.get_version())
    print("Device status:", tenma_ps.get_status())

    # Set voltage and current on channel 1
    tenma_ps.set_voltage(channel=1, voltage=5.0)
    tenma_ps.set_current(channel=1, current=1.0)

    # Read voltage and current from channel 1
    voltage = tenma_ps.read_voltage(channel=1)
    current = tenma_ps.read_current(channel=1)
    print(f"Channel 1 Voltage: {voltage} V")
    print(f"Channel 1 Current: {current} A")

    # Turn on and off the power supply
    tenma_ps.turn_on()
    print("Power supply turned ON.")
    tenma_ps.turn_off()
    print("Power supply turned OFF.")

Initialize the Tenma power supply interface.
