Overview:

  • Dc-Dc Step Down Adjustable Module 

  • Input 5V-32V

  • Output 0.8V -30V

  • Output current: Adjustable up to 5A

  • Constant Current

  • Constant Voltage

  • Lithium Battery Charger

Description:

This is 5A Contant Current Constant Voltage Dc-Dc Step Down Adjustable Buck Power Module.

Features:

  • The  module uses imported high-quality chips, high efficiency (up to 95%) , low heat generation, maximum 5A current and the output is very stable.

  • This module uses the low- ESR original Sanyo filter capacitor, which can make the ripple voltage as low as 50m.

  • This module uses machine patch, reflow soldering, and each module undergoes two hours of aging test before shipment to ensure high reliability.

  • This module is an adjustable step-down module that can be used to change the output voltage by adjusting the blue adjustable resistor on the module. The input and output voltage difference is 1V, and the minimum output voltage is 0.8V.

  • Wiring must be proper otherwise, the module may be damaged.

Specifications:

  • Modular nature: Non-isolated  buck module

  • Rectification method: Asynchronous rectifier

  • Input voltage: 5V - 32V

  • Output voltage: 0.8V - 30V

  • Output current: Adjustable up to 5A

  • Conversion efficiency: 95% (highest)

  • On-off level: 300KHz

  • Output ripple: 50mV (maximum) 20M bandwidth

  • Voltage regulation: ±2.5%

  • Operating temperature: -40°C to +85°C

  • Dimension (mm): 51 * 26.3 * 14 

Battery charging method:

  • Determine the floating voltage and charging current of the rechargeable battery, the input voltage of the module.

  • Adjust the constant voltage positioner and adjust the output voltage to about 5V. 

  • Use the multimeter 10A current block to measure the output short-circuit current, and adjust the constant current potentiometer to make the output current reach the predetermined charging current value.

  • The charging lamp current is shipped by default to 0.1 times the charging current (constant current value). 

  • Adjust the constant voltage position device to make the output voltage reach the float voltage.

  • Connect the battery and try to charge (1, 2, 3, 4, 5 steps are the module input power supply, the output is not connected to the battery).

 LED constant current driving method:

  • Determine the working current and maximum working voltage of the LED you need to drive.

  • Adjust the constant voltage positioner and adjust the output voltage to about 5V. 

  • Use the multimeter 10A current block to measure the output short-circuit current, and adjust the constant current potentiometer to make the output current reach the predetermined LED working current.

  • Adjust the constant voltage position device to make the output voltage reach the maximum working voltage of the LED.

  • Connect the LED, Test machine (1, 2, 3, 4 steps are connected to the power supply of the module, and the output is not connected to the LED light).

Package Includes:

  • 1 x Constant Current/Voltage 5A Lithium Charger Dc-Dc Step Down Adjustable Module Input 5V-32V Output 0.8V -30V
