  • Module Name: 12A synchronous rectifier buck module, constant voltage constant current.
  • Module Nature: non-isolated step-down module (BUCK) synchronous rectification.
  • Input Voltage: 4-32V (limit 35V) Please keep the voltage margin.

Description:

This is a DC-DC 4-32V to 1.2-32V 12A Adjustable Step-Down Buck Converter Constant Voltage Current Module Solar Lithium Charging Driver.

Specification:

  • Module Name: 12A synchronous rectifier buck module, constant voltage constant current.
  • Module Nature: non-isolated step-down module (BUCK) synchronous rectification.
  • Input Voltage: 4-32V (limit 35V) Please keep the voltage margin.
  • Output Voltage: 1.2-32V continuously adjustable (default output of about 18V, if the power to the module and found that the left and right rotary voltage potentiometer output voltage has not changed, you first turn the voltage potentiometer counterclockwise rotation of more than 15 laps)
  • Input and output minimum pressure difference: 0.8V
  • Output Current: 0-12A long time natural heat within 8A, the temperature does not exceed 60 degrees. Please reduce power when the ambient temperature is high.
  • Output Constant Current Range: 0-12A
  • Operating Temperature: -40 ~ +85 degrees
  • Operating Frequency: 150KHz
  • Conversion Efficiency: up to 98% (efficiency and input, output voltage, current, pressure related)
  • Short Circuit Protection: Yes (limit current is current constant current value)
  • Input Reverse Protection: None (if required, enter the string in the input diode)
  • Output anti-backlash protection: none

Features:

  • Small size
  • Simple wiring
  • Adjustable output voltage
  • Adjustable output current
  • High quality terminal block

Method of setting voltage and current:

  • Set the output voltage: according to the battery you want to charge the float voltage, or string, parallel to the LED voltage, adjust the constant voltage potentiometer (CV), the output voltage is set to the required voltage. (Without load).
  • Set a constant current value: the first CC potentiometer counterclockwise 20 laps or so, with a multimeter 20A current file short-circuit output, adjust the CC potentiometer to you need to set the current value.
  • Constant current set when the voltage is higher than 1.2V, otherwise the constant current function will be invalid.
  • Please use this product, the module input and output are not together, this will cause the module's current sampling resistor is bypassed, so that the module can not adjust the output current size, then the case of large load easily Burn the module.
  • Long work to keep within 150W, the limit should not exceed 200W, otherwise it will burn.

Application:

  • DIY a power supply, with constant current function, not afraid of the use of the process will be short-circuit, you can protect the load.
  • For a variety of battery charging, according to different voltage and capacity of the battery set the charging voltage and charging current.
  • With solar panel power for a variety of battery charging, with constant current function, to prevent the battery overcharge, the effective protection of the battery.
  • Drive high-power LED, free serial and parallel combination.

Using Methods:

  • Used as a normal buck module with over-current protection capability
  • Used as charger for Lithium battery, battery, nickel-cadmium nickel-hydrogen battery
  • Used in solar panels, wind turbines, etc
  • Used as High-power LED constant current drive module.

Package Included:

1 x DC-DC 4-32V to 1.2-32V 12A Adjustable Step-Down Buck Converter Constant Voltage Current Module Charging Driver
