【Switching power supply instructions】
The following description uses the DPM8624 as an example. The
DPM8608 operates in the same way as the DPM8624. The difference is in the
current display. The DPM8608 and DPM8605 currents display three decimal
places such as: 3.000, and the DPM8624 and DPM8616 currents display two
decimal places such as 03.00.

PT: Overheat protection indicator, when the
temperature is greater than 80 °C, the PT light
is on to indicate overheat protection.
CV: Constant voltage indicator, CV indicator light
indicates constant voltage output.
CC: Constant current indicator, CC indicator light
indicates constant current output.
COM: Communication indicator, when there is an
instruction input, the COM light will be on, indicating
communicating.
First, the use of voltage and current adjustment and
shutdown output instructions
Connect the input and output correctly to ensure that the input voltage is
within the required range. Reverse connection is strictly prohibited. The input
voltage must be higher than the output voltage by more than 0.5V.
Note: Input voltage range: 10V~75V;
Output current range: 0~16A (DPM-8616), 0~24A (DPM-8624);
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, the “A ”digital tube displays the current,
the decimal point of the voltage display value is in the second position (such
as 00.00), and the decimal point of the current display value is in the first
position (such as 0.000). After the setting is completed, press OK to turn on
the output. At this time, the CV or CC light is on to indicate that the output
state is turned on. The method of setting the voltage and current value is as

Corr calibration function introduction
1.When the set voltage is greater than 20V, for example, 25V is set as the
output voltage, but the load is not connected, the display voltage of 25V and
the current of zero point (that is, the current is calibrated to zero) are
calibrated.
2.When the output is turned off, the display voltage of zero and the display
current of zero are calibrated.
3.When the output is short-circuited and the current output is greater than 2A,
for example, setting the current output as 3A, the calibration current value of
3A is calibrated.
Temperature display and fan speed introduction
The temperature is displayed as the temperature of the instrument, which can
control the fan speed and over-temperature protection. When the temperature
is greater than 40 °C, the fan starts working, and the fan speed increases by 1
level for every 5 °C increase. When the temperature reaches 60 °C, the fan
rotates at maximum wind speed, when the temperature is greater than 80 °C,
the product over temperature protection automatically turns off the output.

Introduction of voltage and current upper and lower limits:
The upper and lower limits of the voltage and current are set voltage upper
limit adjustment limits and lower limit adjustment limits. For example: set 30V,
5A in the main interface, enter the voltage and current upper limit save
position, press OK to save it as the upper limit of voltage and current, and the
product's voltage adjustment range is up to 30V, the maximum current is 5A.
The same method can also set the lower limit of adjustment.
Communication protocol function:
There are two kinds of communication protocols: simple communication
protocol and MODBUS communication protocol, which can be selected on the
product. We can provide communication protocols.
Simple communication protocol is our custom communication protocol, it
is easy to understand.
MODBUS communication protocol is the standard MODBUS
communication protocol.
Quick response function introduction:
After the quick response is turned on,the response time is short when the
voltage is adjusted from high to low. For example, when the output is 30V,
adjust it directly to the output of 5V. When the quick response is not turned on,
it takes 5 seconds to reduce from 30V to 5V. After turning on the quick
discharge, it takes less than 1 second to reduce from 30V to 5V.
Power-on default status setting introduction:
The default state of power-on refers to whether the output is turned on or off
by default when the power is turned on. When this function is enabled,After
the power is turned on, the output voltage and current values are directly
turned on without operating.
