Dc To Dc Converter

The 300W 10A DC-DC Step-down Buck Converter 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 10 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 20C to 100C 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 10A(for continuous use it is recommended up to 8A with additional cooling fan).

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 wont 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.

1. First, determine the float voltage and charging current required by the battery to be charged (the target battery). The target battery disconnected from the module output, apply a voltage of 7V 32V to the module input, being sure to observe correct polarity.
2. Using the CV trimmer, adjust the output voltage to about 5V.
3. Switch your multimeter into its 10A current scale and measure the modules short-circuit output current. Turn the CC trimmer to.
4. adjust the current to the charging current required by the target battery.
5. Using the CV trimmer, adjust the modules output voltage to the float voltage required by the target battery.
6. Connect the target battery to the module output, observing correct polarity. Charging of the battery should commence.

3. Turn lights Current: current value * (0.1), turn the lamp current and constant value linkage, such as the constant value of 3A.
4. Turn the lamp current is set to a constant current of 0.1 times (0.1 x 3A = 0.3A), when the constant 2A, when adjusted to the current value, then turn the lamp current constant current of 0.1 times (0.1 x 2A = 0.2A).

USB terminals are one of the most used terminals to power the electronic devices from battery  chargers like wall charger and battery banks as they are robust and have been in use for many years now and are mainly used in medical equipment, phone chargers, powering development boards and small battery powered devices like dc motors etc. It is hard to read voltage and current flowing through it if something is not working so this USB Current and Voltage Tester which works as Ammeter and Voltmeter both to determine and debug the USB connector. This dongle plugs between the USB connector and output devices. You can use this device from the 3.5-7VDC input voltage (although most USB devices tend to hover around 4.75 to 5.25) and up to 3A of current. It flips between voltage and current readouts every 3 seconds or so.

This is the voltage boost converter module provides 5V DC stable voltage output at various input range between 1.5V to 5V. This small tiny circuit boosts the voltage level and provides the amplified stabilized 5V output.

1. Input voltage cannot be greater than the nominal voltage, otherwise, it will burn out the module
2. Input power must be greater than the output power, otherwise, the output voltage will be less than the nominal voltage.
3. Output load cannot be greater than the nominal load, otherwise, the output voltage will be less than the nominal voltage.
