:OUTPut Commands
The :OUTPut commands are used to enable or disable the channel output, query the channel output mode,
set and query the overvoltage/overcurrent protection information.

Remarks
DP700 series power supply can work in the constant voltage (CV) or constant current (CC) mode. 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. If the power supply should go into a mode of operation that is neither CV
nor CC, the power supply is unregulated (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.
