The user can configure:
-
Amplitude: desired output current value.
-
Sign: a positive sign represents a current sourced from the power supply. A negative
sign represents a current sunk by the power supply.
-
Setpoint limitation: this limitation can be lower than the maximum power supply
output current. It can be useful when the power supply is connected to batteries since
they may have different current limits for charging and discharging and those limits
may be lower than the maximum power supply current.
Depending on the loads connected, the voltage limitation may be useful too and is
available in any mode.

Voltage mode
The voltage mode is based on a PID controller with dynamic saturation limits which depend on
the current limit configured. The power supply will limit the output current in case of reaching
the configured limit.
