1. Production Introduction

1.1 Production Synopsis

DPS3012/DPS5015/DPS5020 combines analog adjustment and digital control, at the

same time it is compact and powerful, and becomes the first choice for many enthusiasts and

laboratory workers. The unit offers non-volatile power off parameter storage and 10

programmable preset memory Data Groups with a shortcut recall function for groups 1 and 2.

All these productions are designed with LCD display, so we can check set Voltage, set Current,

output Voltage, output current, output power, input Voltage and so on. On the right side of

the main interface, we can see output enabled or disabled, Constant Current or Constant

Voltage mode of operation, abnormal condition warning, keypad locked or unlocked state

and the Data Group in use. The data setting interface allows adjustment of Over-Current,

Over-Voltage and Over-Power protection values, Preset value, LCD brightness and whether

the power is turned on or the like.

This product has 3 versions, Non-communication version, USB communication version,

USB + Bluetooth communication version. Communication version can be connected to PC,

Bluetooth version can be connected to Android mobile phone. (Note: DPS3012 only has no

communication)

This module has many advantages, small size, advanced function, good visual effect,

high operability, high-precision, it can be used independently or be inset into the device and

been widely applied.

KEY: Button Cable, connect to the display panel KEY

The module is DC-DC step-down output. It must ensure that the input Voltage is 1.1

times higher than output Voltage. Under natural heat dissipation conditions, it can be output

at full load. Please install a fan in the casing. Ensure the display module cable are connected

in the right way, otherwise it will not display properly.

The input Voltage range is DC 6.00-60.00V. 60.00V DC is the maximum input Voltage

limit and AC or AC Mains supply 220V must NEVER under any circumstances be connected to

this unit . Do not reverse the battery when charging. Incorrect use will cause the product to

burn out. Please strictly follow the above wiring instructions and precautions.

Exceeding the limit Voltage, using AC as input, wiring error and battery charging reverse

will cause damage. When use power supply with output capacity higher than 20A, be sure to

put the power switch at input place of input power supply. Some damage is irreversible, so

be careful when using the module.

The Bluetooth communication module follows the V2.1+EDR Bluetooth specification,

connect digital power supply and communication module with cables (you need to enter

the communication setting interface to initialize the communication parameters of the

Bluetooth module if it is the first time to use Bluetooth communication function).The red

LED of Bluetooth communication module starts to flash after the digital power is turned

on, that means the Bluetooth can be searched. Open the Bluetooth of your computer;

right click on the Bluetooth icon to add the device. Laptop can use its own Bluetooth;

desktop can use the recommended USB Bluetooth adapter, the USB adapter driver will be

automatically installed after plugging in the desktop. You can see Bluetooth icon appears

in the desktop status bar (lower right corner).Search for a Bluetooth device. The last three

digits of the device represent the digital power address code.

9/32

Enter the device's pairing code when connecting to Bluetooth. Default 1234.

Select the connected Bluetooth device, check the Bluetooth serial port COM that the

computer is using, and the COM port of the outgoing direction (DPS5015_001'Port') is the

serial port of the Bluetooth connection.(Note: Win 7 system, select the Bluetooth device,

right click to view the properties, display the following window, view the COM port of the

Bluetooth settings, select the "outgoing direction" serial port to connect; Win 10 system,

select the Bluetooth device, click "More Bluetooth option", the following window is

Note:

The power supply voltage of communication interface is DC 3.3V and power supply

ability is limit. Don’t connect other big power Bluetooth or WIFI module, otherwise it will be

burnt.

When using the Bluetooth communication function, if power off for digital power supply,

you need to choose COM interface to connect Bluetooth module again after power on.

If the LED on Bluetooth module is flashing, it shows it is on the state of disconnection.

If LED is lighting, it shows it is on the state of connection.

When using Bluetooth function, don’t put Bluetooth module in the metal box,

otherwise it will affect signal strength, Bluetooth communication distance is up to 10 meters

in an open and unobstructed condition.

When modifying communication data of digital power supply, you must disconnect

Bluetooth with PC, the LED will be flashing. Otherwise you can change the data of Bluetooth

board.

For computer operating system, please install official version. if you install pirated or lite

operating system, there may be a lack of Bluetooth virtual serial port driver on those

operating system, and the system can’t assign COM port to Bluetooth board. And it can’t

communicate with the upper computer.

Do not touch components on the Bluetooth communication module, they are fragile

and can be easily broken.
