Buck Boost Converter 4A Module With LCD Display input and output voltage; output current; output power; Input anti-reverse protection; reverse connection will not burn.What is the difference between a buck and a boost converter?Output anti-intrusion, the battery charges without additional anti-reflux diodes;
Button controls the output’s ON or OFF status, and you can set the power-on default to ON or OFF;
Output ripple small, LC filter; With a heat sink, send module support for an isolation column.

  How to use: 

• • Used as a normal buck-boost module with overcurrent protection.
  •  Adjust the CV constant voltage device to make the output voltage reach the voltage you want.
  • Measure the output short-circuit current with a 10A ammeter (directly connect the two test leads to the output), adjust the constant current potentiometer, and make the output current reach the preset overcurrent protection value. (For example, the multimeter displays a current value of 2A.
  • Used as LED constant current drive module.
  • Make sure you need to drive the LED’s operating current and maximum operating voltage;
  • Under no load conditions, the multimeter measures the output voltage and adjusts the constant voltage positioner to make the output voltage

Package Included:

• 1 x Boost Converter 4A Module With LCD
