open() → None

Open the driver’s underlying transport.

close() → None

Close the driver’s underlying transport.

set_voltage(voltage: float, channel: int) → None

Set the output voltage (volts) on channel.

get_voltage(channel: int) → float

Query the measured output voltage (volts) on channel. Output may vary from voltage setpoint outside of constant voltage mode.

set_current_limit(

current_limit: float,

channel: int,

) → None

Set the current limit (amperes) on channel.

get_current(channel: int) → float

Query the measured output current (amperes) on channel. Output may vary from current-limit setpoint outside of constant current mode.

get_voltage_setpoint(channel: int) → float

Query the configured voltage setpoint (volts) on channel. Output may vary from actual measured voltage outside of constant voltage mode.

get_current_setpoint(channel: int) → float

Query the configured current-limit setpoint (amperes) on channel. Output may vary from actual measured current outside of constant current mode.

output_enable(enable: bool, channel: int) → None

Switch the output on or off. The GPD-3303D has one output switch, so channel is only validated and every channel is affected.

get_output_status(channel: int) → bool

Query the output state, which is shared by every channel.

get_operating_mode(

channel: int,

) → OperatingMode

Query whether channel is regulating in constant voltage, constant current, unregulated, or off.

set_overvoltage_protection_level(

voltage: float,

channel: int,

) → None

Set the overvoltage protection threshold (volts) on channel.

get_overvoltage_protection_level(channel: int) → float

Query the overvoltage protection threshold (volts) on channel.

set_overvoltage_protection_enabled(

enabled: bool,

channel: int,

) → None

Enable or disable overvoltage protection on channel.

get_overvoltage_protection_enabled(channel: int) → bool

Query whether overvoltage protection is enabled on channel.

set_overvoltage_protection_delay(

delay: float,

channel: int,

) → None

Set the overvoltage protection trip delay (seconds) on channel.

get_overvoltage_protection_delay(channel: int) → float

Query the overvoltage protection trip delay (seconds) on channel.

set_overcurrent_protection_level(

current: float,

channel: int,

) → None

Set the overcurrent protection threshold (amperes) on channel.

get_overcurrent_protection_level(channel: int) → float

Query the overcurrent protection threshold (amperes) on channel.

set_overcurrent_protection_enabled(

enabled: bool,

channel: int,

) → None

Enable or disable overcurrent protection on channel.

get_overcurrent_protection_enabled(channel: int) → bool

Query whether overcurrent protection is enabled on channel.

clear_protection(channel: int) → None

Clear every latched protection trip on channel. The output stays off until re-enabled.

get_overvoltage_protection_tripped(channel: int) → bool

Query whether overvoltage protection has tripped on channel and not been cleared.

get_overcurrent_protection_tripped(channel: int) → bool

Query whether overcurrent protection has tripped on channel and not been cleared.
