Description: Buck-boost module (constant voltage constant current LCD version) Product highlights: 1. LCD input and output voltage, output current output power; 2. Input anti-reverse protection, reverse connection will not burn; 3. Can be step-up and step-down, the output voltage 0.5-30V arbitrary regulation, limiting the current 0-4A arbitrary regulation; 4. output anti-intrusion, the battery charge without additional anti-reflux diodes; 5. Button control output ON / OFF status, and you can set the power-on default is ON or OFF; 6. Ascending and descending chip used as the main controller, external 60V 75A MOS tube as a switch, double 60V 5A SS56 Schottky rectification, 60V voltage value, superior to the market immature XL6009 / LM2577 program (a lot Device pressure value is not enough, MOS tube and Schottky diode pressure value must be greater than the input plus input voltage value); 7. Output ripple small, LC filter; 8. With heat sink, send module support isolation column. Product parameters: Input voltage: 5.5-30V (input voltage 5V, you can normally achieve buck-boost, but the voltage and current meter values ​​are not accurate; less than 4.7V, undervoltage protection) Output voltage: 0.5-30V Output current: long-term stable work in 3A, strengthen the heat can reach 4A Output power: 35W natural cooling, heat dissipation to enhance 50W Voltage display resolution: 0.05V Current display resolution: 0.005A Conversion efficiency: about 88% Soft-start: Yes (very powerful with load startup, startup may fail) Input reverse protection: Yes Output anti-intrusion: Yes Short circuit protection: yes Working frequency: 180KHZ Size:66 * 48 * 21mm( L * W * H ) Mounting hole: 4mm in diameter Weight: 46g Function Description: 1. Module has IN / OUT, ON / OFF two buttons: IN / OUT button to switch the input voltage and output voltage display, long press to switch the output current output power display; ON / OFF button control output ON or OFF, long press Set power on default output status is ON or OFF. 2.CC is the current setting potentiometer, clockwise rotation, can increase the set current, when the load current reaches the set current, enter the constant current state, CC constant current indicator (red) lights up; the right CV is the voltage setting Potentiometer, clockwise rotation, can increase the output voltage. ON indicator is the output status indicator, when the output voltage is on, otherwise off. Package Included: 1PC x DC-DC 5.5-30V 0.5-30V 35W Buck Boost Power Supply Module Adjustable LCD digital Voltmeter Ammeter
