Buck Boost Converter Display, DROK Buck-Boost Board DC 5.5-30V 12v to DC 0.5-30V 5v 24v Adjustable Constant Current Voltage Step UP Down Voltage Regulator 3A 35W Power Supply Module

Description

LCD input and output voltage, output current output power
Input anti-reverse protection, reverse connection will not burn
Can be step-up and step-down, the output voltage 0.5-30V adjustable , limiting the current 0-4A adjustable.
Output anti-intrusion, the battery charging without additional anti-reflux diodes;
Button control output ON / OFF status, and you can set the power-on default is ON or OFF
Ascending and descending chip used as the main controller, external 60V 75A MOS tube as a switch, double 60V 5A SS56 Schottky for rectification, enough pressure, enough power.
Small output ripple, with LC filter


LCD Display: the voltage regulator module is designed with LCD, can display input and output voltage, output current and output power; voltage display resolution is 0.05V, current display resolution is 0.005A.

Application: power supply with over-current protection，power conversion， LED constant current driver module，bilge pump, 12v lead acid battery, Drone, folding solar panel, air matress pump, LED strip, power some small 5V to 12V, 15V CPAP machine,test meter, circuit test, solar project

Safe Protection: with reverse connection protection at input and with anti-backflow at output terminal, so there is no need to add an anti-backflow diode when charging the battery.

ON/OFF Button: Short Press to select whether output . Long press (more than 3second) is used to restore default settings.IN/OUT Button: Short Press to switch display input voltage or output voltage. Long press is used to switch display output current or output power.
