4. Disconnect the shorting lead from the output terminals. The power supply will
now automatically switch into current limiting mode (current regulation) as
soon as the preset current level is reached.
Setting the
Supply to
Operate in CI
Mode
To operate the supply in CI mode:
1. Set the current limit as described above.
2. Set the voltage control fully clockwise or to the compliance voltage of the
circuit.
As soon as the supply starts operating in current mode, the red current mode
LED will turn on.
Automatic
Mode
Crossover
The automatic crossover system allows the power supply to automatically switch
operating modes in response to changing load requirements. For example, if the load
current attempts to increase above the setting of the current adjust control, the unit
will switch automatically from Constant Voltage to Constant Current mode. If you
lower the load requirements, the supply will automatically return to Constant Voltage
mode.
Shipped Configuration (Local Control Mode)
The factory ships units already configured for local control (front panel) operation.
See Table for a summary of this configuration.

Use the front panel controls to adjust
output voltage and current limit
settings. See Section for front panel operation.

analog programming procedures.
The OVP set point is adjusted at the
front panel to over 110% of rated
output voltage. See
