Modes of Operation
3.2.1
Normal Mode
DP series power supplies are normally shipped with its configuration set for rotary mode input,
local sensing, internal control, and external control. This configuration is set by front panel
commands described in Section 3.1.1.3 and 3.1.2.2 for DPD and DPA Series power supplies,
respectively. With this configuration, the operator can select either a constant voltage or a
constant current output using the front panel controls.
3.2.2
Constant Voltage
To select constant voltage output, proceed as follows:
With the supply off, set both rotary controls to full counterclockwise. Press the V/I dis key and
advance the voltage and current controls for the desired output voltage and the desired crossover
current. The crossover current is the current at which the power supply becomes a constant
current source.
Connect the load and turn on the power supply. The output voltage should be close to the
voltage set point. If a load change causes the current limit to be exceeded, the power supply will
automatically crossover to constant current output at the preset current limit and the output
voltage will drop proportionately. In setting the current limit, allowance must be made for high
peak currents which can cause unwanted crossover (see Section 3.10).
3.2.3
Constant Current
To select constant current output, proceed as follows:
With the supply off, set both rotary controls to full counterclockwise. Press the V/I dis key and
advance the voltage and current controls for the desired output current and the desired crossover
voltage. The crossover voltage is the voltage at which the power supply becomes a constant
voltage source.
Connect the load and turn on the power supply. The output current should be close to the current
set point. If a load change causes the voltage limit to be exceeded, the power supply will
automatically crossover to constant voltage output at the preset voltage limit and the output
current will drop proportionately.
