1. Connect the input and output correctly, and reverse connection is strictly
prohibited. Ensure that the input voltage is within the required range. The
input voltage must be 0.5V or more above the output voltage.
Note: Input voltage range: 10V~75V;
Output current range: 0~5A(DPM8605), 0~8A(DPM8608),
0~16A(DPM8616),0~24A(DPM8624),
0~50A(DPM8650)
Output voltage range: 0~60V.
2. Set the required voltage and current values. It should be noted that the V
digital tube displays the voltage, and the A digital tube displays the current.

5V, 3A at start-up.
Press button shortly,
a value flashes.
The flashing position can
be changed by and
buttons, such as adjusting
12V, 5A. Press to exit
the adjustment state.
Press to turn the output
on or off. When the load
current is less than the set
current, the output is
constant voltage output and

When the load current
reaches the set current,
the output is the set
current, constant current
output, and the CC
indicator is on.
Press the button
continuously, the flashing
position will move at
different positions of
voltage and current.

Corr Calibrating Function Introduction
1.When the set voltage is greater than 20V, for example: set 25V output, but
not connected to the load, the display voltage and the zero point current of
25V is calibrated (that is, the current is calibrated to zero).
2.When the output is turned off, the zero display voltage and zero display
current are calibrated.
3.When the output is short-circuited and the current output is greater than 2A,
for example, if the 3A output is set, the displayed current value of 3A is
calibrated.
Temperature Display and Fan Speed Introduction
The temperature is displayed as the temperature of the current power
device, which can control the fan speed and over-temperature protection.
When the temperature is greater than 40 ℃, the fan starts. For every 5 ℃
increase, the fan speed increases by 1 level. When the temperature reaches
60℃, the fan rotates at the maximum wind speed. When the temperature is
higher than 80 ℃, the product's over-temperature protection will automatically
cut off the output.
3. SET Function Instructions

Voltage and Current Limit Function Introduction:
The upper and lower limit of the voltage and current is to set the upper
and lower limit of the voltage and current adjustment. For example: set 30V,
5A on the main interface, enter the voltage and current upper limit saving
location, and press OK to save them as the voltage and current upper limit.
The maximum voltage adjustment range of the product is 30V and the
maximum current is 5A. The same method can be used to set the lower
adjustment limit.
Communication Protocol Function:
There are two kinds of communication protocols: simple communication
protocol and MODBUS communication protocol, which can be selected on the
product. Communication protocols are provided by our company.
Simple communication protocol is our custom communication protocol. It
is easy to understand.
MODBUS communication protocol is the standard MODBUS
communication protocol.
Quick Discharge Function Introduction:
After the fast discharge is turned on, when the voltage is turned from high
to low, the response time is relatively short.
For example: 30V is being output, and the output is directly adjusted to
5V. When fast discharge is not turned on, it takes 5 seconds to drop from 30V
to 5V, but if the fast discharge is turned on, it takes less than 1 second to drop
from 30V to 5V.
Power-on Default State Settings:
The power-on default state refers to whether the output is turned on or off
by default when the power is turned on. When this function is turned on, the
Press the button shortly to
enter the baud rate selection
interface. There are 7 groups of
baud rates in Kbps. Use the
or button to change the baud
rate, and then press the
button. The setting is finished.
Press the button shortly to enter
the communication address selection
interface. There are a total of 99
communication addresses from 01 to
99. Change the communication
addresses by pressing the or
button, and then press .The
setting is finished.
