● Ammeter: 0 - 2A (only display module output current)
● Voltmeter: Input 4.5 - 24V， output 0.9 - 20V
● Output current adjustable: 0 - 2A
● Output power: Max. 20W
● Voltmeter accuracy: +/- (5 +1 words)
● Input voltage range: 4.5 - 24V
● Output voltage range: 0.93 - 20V (buck mode， the input must be greater than the output 2V)
● IN+: Input positive， IN-: Input negative， OUT+: Positive output， OUT-: Negative output (Note: IN- and OUT- not of work)
● Digital display size: 0.99 inch
● Dsplay color: Green
● Left button: In boot default state， the display show voltage
● U. when push button， the display shows working current
● A. Press button again， voltage and current alternately display (5s)
● Press button once again， back to initial voltage state
● Right button: Be used to switch voltage mode
● Voltage indicator: When voltage indicator lights on， the digital display shows input voltage
● When voltage indicator lights off， the digital display shows output voltage
● Current indicator: Show that the module is in constant current state
● Voltage potentiometer(VADJ): Adjust potentiometer clockwise， the output voltage increases
● Adjust potentiometer counter-clockwise， the output voltage drops (In constant voltage working state)
● Current potentiometer(IADJ): Adjust potentiometer clockwise， the output current increases
● Adjust potentiometer counter-clockwise， the output current drops (In constant current working state)
● Note: Be sure to leave room for use otherwise it will damage the voltage
