Usage Notes For DC-DC USB Buck Boost Power Supply Voltage Regulator With Display - 5V to 3.3/9/12/24V:

Mode Switching:

The default is the Power Output Mode PER at first

Keep press button ˜ON/OFF™ to switch mode

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

Power Output Mode PER:

Input from standard USB male socket ,Micro USB female socket and ˜VIN+/VIN-™

Output from ˜OUT+™ and ˜OUT-'.The ˜COM™ terminal can not be used at PER mode.

Rotate the potentiometer to adjust the output voltage

There is a symbol ˜OUT™ when work in PER mode

Terminal ˜COM™ unavailable at PER mode

Short press button ˜ON/OFF™ to turn ON or OFF output voltage .At this time, screen will display 0V

Keep press button ˜ON/OFF™ for 2 second to switch display output current or output power at the second line

Keep press button ˜ON/OFF™ for 5 second to turn ON or OFF display screen backlight .But the module can output voltage normally

Keep press button ˜ON/OFF™ for 10 second to turn switch work mode PER or VAH

The module supports over-power protection. If the rated power is exceeded, the module will automatically stop output voltage and the LCD will display ˜OPP™ and flash

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

Multi-function Meter Mode VAH:

Module work voltage : Standard USB male socket ,Micro USB female socket and ˜VIN+/VIN-™ are used to provide work voltage from module.

Measuring voltage : ˜V™ and ˜COM™ terminals are used to measure Measured Device Voltage.

Measuring current : ˜A™ and ˜COM™ terminals are used to measure Measured Device Current.

Short press button ˜ON/OFF™ to switch display Measured Device Voltage ,Current ,Power ,Time .And also can measure Battery capacity ,Battery discharging time if connect battery.

Keep press button ˜ON/OFF™ for 5 second to turn ON or OFF display screen backlight .But the module can output voltage normally.

Keep press button ˜ON/OFF™ for 10 second to turn switch work mode PER or VAH.

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

Potentiometer is not available at VAH mode.

Calibrate Voltage/Current:

Calibrate Voltage :Keep press button ˜ON/OFF™ before power ON and then power ON and release button .Automatically enter calibration mode after 5 second. The voltage display will flashing. Short press button to adjust and calibration voltage. Adjustment range is -0.2V~0.2V.Enter current calibration mode if keep press button for 2 second.

Calibrate Current :Enter current calibration mode if keep press button for 2 second after Calibrate Voltage. The current display will flashing. Short press button to adjust and calibration voltage. Adjustment range is- 0.02A~0.02A.Automatically save parameters and return to the normal display interface if keep press button for 5 second.

User needs to repeat the correction multiple times. If the voltage(current) error exceeds 0.2V(0.02A).

For example :Change 12V to 12.5V:

First calibration :Change 12V to 12.2V

Second calibration :Change 12.2V to 12.4V

Third calibration :Change 12.4V to 12.5V

Use steps:

Connect to power supply from input terminal;

Set work mode by keep press button ˜ON/OFF™ for 10second;

Connect load or Device Voltage;

Rotate pot
