Ammeter: 0.00-2.00A(Only display output current) Voltmeter: Input 4.5-24.0V output 0.9-20.0V Display color: Red Input voltage: 4.5-24V(Please below 24V when use) Output power:20W max Output voltage:0.9v-20v (Input must be greater than the output above 2V) Output current: 0-2A Adjustable Voltage meter accuracy: ± (5 ‰ +1 digit) In+: Input positive In-: Input negative Out+: Output positive Out-:Output negative (note: in- and out- can not connect together) Weight: 25g Dimensions: 51.5 *33 *20mm(L*W*H) Function: 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: Please don't use the module to charge the battery. If the input end is not supplied the power, reverse voltage of the battery will damage the module. {if you must use the module ,please add a diode in the output }. Delivery list: 1 x DC/DC Buck Converter Module
