Description

The 4A DC-DC Step-down Adjustable Constant Voltage Module can be used to get adjustable output voltage ranges from 1.5V to 35V. The module provides a wide range of current output up to 4 A. With heat sink mounted it can easily manage to run high power application continuously (provided that for continuous high power output you need to use a cooling fan on the heat sink).
The Module is made from a dedicated benchmark IC and high-precision current sensing resistor, proving a more stable constant current, (when 20?C to 100?C constant current 1A, temperature drift less than 1%); and therefore it is particularly most suitable for LED driver applications. The output current of the module can be raised up to 4A.
To enhance the stabilization in output voltage has four high-frequency capacitance which gives the lower output ripple. Double heat sink design provides easy and fast heat dissipation. MOS Schottky diode independent heat sink, which heat dissipation is good, and won?t affect each other. Also using large size Sendust Core and double pure copper wiring, improve working efficiency, reduce fever.
The module has onboard 3296 multiturn potentiometers for high accuracy voltage and current regulation to provide good stability. As voltage and current are adjustable, it gives very easy to use at multiple Application such as battery charging, LED Driver power supply, Vehicle Power Supply, etc which makes the module Multipurpose and hence this module is always in demand from our maker because of its wide range of application and low cost.
Note: Refer to manual for more info.
