Constant Voltage Output
The DP700 series power supply can work in the constant voltage (CV) or constant
current (CC) mode
[1]
. In the CV mode, the output voltage equals to the voltage
setting value, and the output current is determined by the load; whereas in the CC
mode, the output current equals to the current setting value, and the output voltage
is determined by the load. This section introduces the operation method for CV
output.
Operation Methods:
1. Connect the load with the channel output terminals
Turn off the instrument. Connect the load with the channel output terminals on
the front panel.
CAUTION
While making a connection, the positive
polarity of the load should be connected to the
(+) terminal of the channel output, and the
negative polarity of the load to the (-) terminal
of the channel output. A misconnection with
the terminals may cause damage to the
instrument and the devices connected to it.
2. Turn on the instrument
Press
to turn on the instrument.
3. Set parameters for the channel output
Set the output voltage
(1) In the main interface, press the
Up/Down arrow key to switch the
parameter focus to "Voltage Setting
Value".
(2) Use the num key or the knob to set a desired value for the output voltage.
Note
[1]
: If the power supply should go into a mode of operation that is neither CV nor CC, the
power supply is unregulated (the channel output mode displayed as UR). In this mode, the output
is not predictable. The unregulated condition may be caused by the fact that the AC line voltage is
below the specifications. This condition may occur temporarily. For example, when the output
voltage is programmed for a large change, the output capacitor or a large capacitive load will
charge up until the current reaches the setting value. During the ramp-up of the output voltage, the
power supply will be in the unregulated mode. During the transition from CV to CC (e.g. transition
caused by a short circuit on the output), the unregulated condition may occur temporarily.
