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.

4.2 Safety Guidelines
Operation to power outlet and power cord: please use polarized power cord and polarized power outlet
for the instrument to ensure the case, output terminal are properly grounded.
To avoid damage, don’t remove the upper case, front or rear panel during operation to the power supply.
Do not touch the upper case or rear panel (heat sink). They are heating bodies and may cause scald.
Operation environment: The power supply should be operated in an environment with good ventilation
and with temperature at 23℃±5℃. Do not operate the power supply in environment with temperature
over 40℃.
Storage: Do not place any other instruments or inflammables on the power supply.
Abnormal operation: Do not apply high voltage or current which is over the rated voltage to the power
supply. Do not connect the positive and negative output terminals on the front panel continuously in the
way of instant short-circuit.
Grounding: Make sure to connect the input and output terminals to earth during the operation to ensure
your safety and the safety of nearby instruments.

Fault shooting: In case of any abnormal phenomenon, please forward the power supply to qualified
technical personnel.
4.3 About AC Input Voltage
The AC input voltage for DPS series is 110V/220V selectable±10%, 50/60Hz. When the power source is
higher than the rated voltage by +10%, please set the output current to 70%~80% of the rating output current to
avoid damage to the power supply.
