INTRODUCTION
DPS series programmable power supply provides continuous adjustable output voltage and current as well as
automatic shift between constant voltage and current. It features with high stability & reliability, high accuracy, 4
groups memories by using digital technology, panel lock, output ON/OFF function, voltage & current limit setting
with password, and intelligent temperature control and alert function.
DPS series power supply has three outputs: two with adjustable output voltage and one fixed output voltage
(2.5V, 3.3V, 5V selectable, for DPS-3033GL-3 only).The two adjustable outputs provide both manual and
programmable control modes. When it is turned on, the unit is default) and in manual model. Pressing TIMER
button to set parameters. Pressing RUN or STOP button to turn on or off programmable control output.
As a constant voltage (CV) and constant current (CC) source, DPS series is able to, even at the maximum
output current, provides a fully rated and continuously adjustable output voltage. For a big load, DPS series can be
used as a CV source, the output current can be adjusted via a current regulator on the front panel; when used as a
CV source, the maximum output voltage can be controlled via voltage regulator on the front panel. That is to say,
the power supply will automatically shift from CV source to CC source when the output current reaches the target
value.
CAUTION:
！
1. The power supply must be operated under the rated line voltage. If the power supply is meant
to work for a long time, it is suggested to use 60%~70% load to as to avoid rapid aging.
2. Avoid frequent short-circuit operations.
3. Do not turn on the power supply when the output terminal is with heavy load. Turn the output
voltage adjustment knob to the lowest value, next connect the load, and then turn on the power
supply. Adjust the voltage/current adjustment knob to set the wanted values.
