Product Details

1.Description:

XY-DUPH is an instrument with integrated buck-boost power supply module and multi-function voltage ammeter and temperature display module.

In ‘PER’ work mode,it can be used as buck-boost power supply module.It can convert to DC 3.5V~12V to DC 1.0V~24V and power is about 2W~3W.

In ‘VAH’ work mode,it can be used as multi-function voltage ammeter.It can be used to measure voltage,current,power,battery capacity,discharging time.

It also can display real time temperature in both work modes.

It is very suitable for technical engineers to develop, debug instrumentation, after-sales engineers travel maintenance, etc.

4.Mode Switching:

1>.XY-DUPH uses a Gear potentiometer to adjust parameters.Press is used as ‘ON/OFF’.Rotate to left is used as ‘UP’.Rotate to right is used as ‘DOWN’.

2>.The default is the Power Output Mode PER at first;

3>.Keep press potentiometer for 10 second to switch mode;

4>.When power is remove, module can remembers current operating mode.The default work will be the same mode when power on at next time.

5.Power Output Mode PER:

1>.Input from standard USB male socket,Micro USB female socket and Type-C female socket.

2>.Output from ‘OUT+’ and ‘OUT-'.The ‘COM’ terminal can not be used at PER mode.

3>.LCD display will display current mode ‘PER’ when start up.And the

4>.There is a symbol ‘OUT’ when work in PER mode.

5>.Terminal ‘COM’ unavailable at PER mode.

6>.Short press potentiometer to turn ON or OFF output voltage.Screen will display 0V and current will flashing at this time.

7>.Keep press potentiometer for 2 second to switch display output current or output power at the second line.

8>.Keep press potentiometer for 5 second to turn ON or OFF display screen backlight.But the module can output voltage normally.

9>.Keep press potentiometer for 10 second to turn switch work mode PER or VAH.

10>.Rotate potentiometer to right or left to adjust output voltage.User also can keep rotate to adjust output voltage continuously and greatly.There is a symbol ‘SET’ will display at the same time.Automatically save the set parameters after 2 second.

11>.Rotate potentiometer to right or left to switch display current temperature when turn OFF power supply output.

12>.XY-DUPH supports over-power protection.It will automatically stop output voltage and the LCD will display ‘OPP’ and flash if output power is more than 3W.

13>.XY-DUPH supports under-voltage protection.It will automatically stop output voltage and the LCD will display ‘LVP’ and flash if output voltage is less than 0.8V.

14>.XY-DUPH supports over-current protection.It will automatically stop output voltage and the LCD will display ‘OCP’ and flash if output current is more than 2A.

15>.The module does not support reverse connection protection, please do not short circuit and reverse.

6.Multi-function Meter Mode VAH:

1>.Module work voltage : Standard USB male socket,Micro USB female socket and Type-C female socket are used to provide work voltage for XY-DUPH.

2>.Measuring voltage : ‘V’ and ‘COM’ terminals are used to measure Measured Device Voltage.

3>.Measuring current : ‘A’ and ‘COM’ terminals are used to measure Measured Device Current.

4>.There is a symbol ‘IN’ when work in PER mode.

5>.Short press potentiometer to switch display current temperature or Measured Device Voltage.

6>.Keep press potentiometer for 5 second to turn ON or OFF display screen backlight.But the module can output voltage normally.

7>.Keep press potentiometer for 10 second to turn switch work mode PER or VAH.

8>.Rotate potentiometer to right or left to switch display Measured Device Power and current.And also can measure Battery capacity,Battery discharging time if connect battery.

9>.The module does not support reverse connection protection, please do not short circuit and reverse.

7.Calibrate Voltage/Current:

1>.Calibrate Voltage:Keep press potentiometer before power ON and then power ON and release potentiometer after 5 second.Automatically enter calibration mode.The voltage display will flashing.Rotate potentiometer to right or left to adjust and calibration voltage.Enter current calibration mode if keep press potentiometer for 2 second.Automatically save parameters and return to the normal display interface if keep press potentiometer for 5 second.

2>.Calibrate Current:Enter current calibration mode if keep press potentiometer for 2 second after Calibrate Voltage.The current display will flashing.Rotate potentiometer to right or left to adjust and calibration current.Automatically save parameters and return to the normal display interface if keep press potentiometer for 5 second.

3>.Voltage and current need to be separately calibrated separately in different work modes. The same way of calibration.

8.Use steps:

1>.Connect to power supply from input terminal;

2>.Set work mode by keep press potentiometer for 10second;

3>.Connect load or Device Voltage;

4>.Set required parameters;

5>.Test and use.

9.Application:
