The GPP series models have additional Load
function on both CH1 & CH2 with 3 modes:
CV (Constanct Voltage), CC (Constant Current)
and CR (Constant Resistance), all of which can
be selected through the function keys on the
front panel. Voltage, current and resistance can
be well regulated in each mode, respectively.
Each output channel is completely
transistorized and well-regulated, and works in
constant voltage (CV) or constant current (CC)
mode. Even at the maximum output current, a
fully rated, continuously adjustable output
voltage is provided. For a big load, the power
supply can be used as a CV source; while for a
small load, a CC source. When in the CV mode
(independent or tracking mode), output
current (overload or short circuit) can be
controlled via the front panel. When in the CC
mode (independent mode only), the maximum
(ceiling) output voltage can be controlled via
the front panel. The power supply will
automatically cross over from CV to CC
operation when the output current reaches the
target value. The power supply will
automatically cross over from CC to CV when
the output voltage reaches the target value. For
more details about CV/CC mode operation,
see page 26.
The front panel display (CH1, CH2) shows the
output voltage or current. When operating in
the tracking mode, the power supply will
automatically connect to the auto- tracking
mode.
