Please read this instruction carefully before using
Constant Voltage Constant Current Programmable
Control Supply Power Module
Product model: DP30V5A
General Information
The constant voltage and constant current programmable control power
supply module put the collection of analog integration and digital control
functions in one. Its adjustable output voltage range is 0-32.00V, step by 0.01V.
Its adjustable output current range is 0-5.000A, step by 0.001 A. This module
has power-down stored function and can store 10 groups preset value. And it
also has the function of extracting quickly two groups stored value. Compared
with the traditional analog power supply, it is more convenient to quickly extract
the voltage or current required. LCD display on the module has the function
digital voltmeter and ammeter. You can view the preset voltage, input voltage,
output voltage, the preset current, output current, output power, etc. on the
output state remind area, you can see that output opens or not, the state of
constant voltage and constant current, output is normal or not, the key is locked
or not, and the current data groups that is being used. On the setting data
interface, you can adjust over-voltage value, over-current value, over-power
value, data set and LCD brightness. This module has many advantages, small
size, advanced function, good visual effect, high operability, high-precision,
being used independently, being inset into the device and been widely applied.

Connection description
IN+: Input positive OUT+: Output positive
IN-: Input negative OUT-: Output negative
Note: Input voltage range is 6-40V and 40V is the
limit voltage; please leave a room to use, or else
it will be burnt. The input must be DC-DC, not AC
220V, or else it will be burnt too. Though this
module has reverse connection protection and
output short circuit protection, you must be in strict
accordance with connection description to
connect. If you connect the supply power with
output, the module will be burnt.

Operating instructions
When connect the power supply, the
screen shows welcome window firstly and
then comes into main interface.
On the main interface, the output set
voltage value and the output set current
value is on the top of the screen.
The big font value on the left are the actual
output voltage, the actual output current
and the actual output power. Input voltage
is on the bottom of the screen. There are some running status icons on the right
of the screen, key lock icon, abnormal output status icon, constant voltage and
constant current icon, data set tip icon and opening or closing output icon.
Set the output voltage and output current on the main interface.
On main interface, press shortly, you can enter into data setting status.
Press coding potentiometer to enter into the status of adjusting the numerical
value you want to adjust. Turn coding potentiometer to adjust the numerical
value. Turn by clockwise rotation to increase the numerical value; Turn by
counterclockwise to decrease the numerical value. If you want to exit adjusting
the numerical value, press shortly. In the same time, the preset value will
be stored. Or you can do nothing in one minute, the status will be automatically
existed and the preset value will be stored too.
Set the data on the data setting interface
On the main interface, you can press twice to enter
into the data setting interface. On the data setting interface,
press shortly or to page up or page down to U-SET
or l-SET, the operation way is consistent with the way of
setting the output voltage and output current on the main
interface.
Set the protection value.
Page up or page down to S-OVP, S-OCP or S-OPP and
then press shortly the coding potentiometer to enter into the
status of adjusting the numerical value you want to adjust. Turn coding
potentiometer to adjust the numerical value. If you want to exit adjusting the
numerical value, press shortly.
Adjust the brightness of screen.
Page up or page down to B-LED, and then press shortly the coding
potentiometer to enter into the status of adjusting the brightness of screen. Turn
coding potentiometer to adjust the numerical value you need. If you want to exit
adjusting the numerical value, press shortly. There are six brightness levels
of LCD screen, 0-5 level. Rank 0 is the darkest; rank 5 is the brightest. You can
choose what you like.

Data setting and store the specified data group.
Page up or page down to M-PRE, and then press shortly the coding
potentiometer to enter into the status of choosing the data groups. Turn coding
potentiometer to choose the data group you need to view. Then the data group
you need will be displayed. Then press the coding potentiometer to enter
into status of changing output state. Turn coding potentiometer to choose ON
or OFF. When choose ON, the data group is extracted and the output status
remain the same. When choose OFF, the data group is extracted and the
output is closed. If you want to exit choosing the data group, press shortly.
Then press shortly or to page up or page down to other place to adjust
the data you need. After data setting done, keep pressing more than 2s,
all the data you set are automatically stored into the specified data group. In
the same time, you can see the group number on the right of screen. Now you
can press shortly back to the main interface.
Function description
Open or close the output:
You can press to open or close the output on any interface.
Lock the button to avoid wrong operation:
On the any interface, you can keep pressing coding potentiometer more
than 2s, all buttons are locked. You can see the key lock icon on the right of
screen. If you want to unlock all buttons, keep pressing coding potentiometer
more than 2s, all buttons are unlocked. The key unlock icon will be display on
the right of screen.
M0-M9 ten data groups:
M0 group is the boot default data group. When you extract the data group
you need, this data group will cover M0 data group and be automatically stored
on M0 data group.
Extract Shortcut storage data group M1 or M2:
On the main interface, keep pressing or more than 2s, the
corresponding data group will be extracted. In the same time the
corresponding data group number will displayed on the right of the screen.
Extract the specified data group:
On the main interface, keep pressing more than 2s, the sequence
number of data group will be displayed on the right of the screen, you can turn
coding potentiometer to choose data group you need. Then press shortly,
you can extract the specified data group you need.
