Power Supply Regulation Modes; Constant Voltage (Cv); Constant Current (Cc); Automatic Mode Crossover - Xantrex GPIB-M-HPD Operating Manual

Power Supply Regulation Modes

The power supply has 2 regulation modes while in the Normal Operation State:
•
•
The CV, CC LEDs on the front panel indicate the regulation mode.
Constant In this mode, the supply's output voltage is constant while the current and power
vary with the load. The power supply will operate in constant voltage mode
Voltage (CV)
whenever the load current I

requirements.
Constant In this mode, the supply's output current is constant while the voltage and power
vary with the load. The power supply will operate in constant current mode
Current (CC)
whenever the load resistance is low enough that the load current I

maintains the output current at the selected value (I
varies with the load requirements.
Automatic
This feature allows the power supply to automatically switch operating modes in
Mode response to changing load requirements. If, for example, the power supply was
operating in Constant Voltage (CV) Mode (I
Crossover
load current (I
supply would automatically switch into Constant Current (CC) Mode and the output
voltage would vary in response to changes in load current. If the additional load was
subsequently removed so the load current was again LESS THAN the current limit
setting, the supply would automatically return to Constant Voltage (CV) Mode.
