LCD Digital Display Buck-Boost Power Supply Module Board Constant Voltage Constant Current Crystal Voltmeter Ammeter Adjustable

LCD Digital Display Buck-Boost Power Supply Module Board Constant Voltage Constant Current Crystal Voltmeter Ammeter Adjustable
Input voltage: 5.5-30V (When the input voltage is 5V, buck-boost can also be achieved, but the voltage and current measurements are inaccurate; under 4.7V, undervoltage protection)
Output voltage: 0.5-30V
Output current: Can work stably in 3A for a long period of time, and can reach 4A under enhanced heat dissipation
Output power: natural heat dissipation 35W, enhanced heat dissipation 50W
Voltage display resolution: 0.05V
Current display resolution: 0.005A
Conversion efficiency: about 88%
Soft start: Yes (high power load module may fail at startup)
Reverse input protection: Yes
Anti-backflow at the output: Yes
Short circuit protection: Yes
Working frequency: 180KHZ
Size: length * width * height 66*48*21mm

Product Description
-LCD can display input and output voltage, output current output power;
-Anti-reverse protection at the input end, reverse connection will not burn;
-Can be boosted, can be stepped down, output voltage 0.5-30V arbitrary regulation, limit current 0-4A arbitrary regulation;
-Anti-backflow at the output end, no additional anti-backup diode is required to charge the battery;
-The button controls the ON/OFF status of the output, and can be set to default to ON or OFF.
-Using buck-boost chip as the main controller, external 60V 75A MOS tube as switch, dual 60V 5A SS56 Schottky rectifier, 60V voltage value, better than the market XL6009/LM2577 immature program (many devices resistance Insufficient voltage value, MOS tube and Schottky diode withstand voltage must be greater than the input plus input voltage value);
-Output ripple is small, with LC filter;
-Contain heat sink, send module support isolation column.
