4A DC-DC Step-down Adjustable Constant Voltage Module

The output voltage ranges of the 4A DC-DC Step-down configurable Constant Voltage Module are configurable, ranging from 1.5V to 35V. The module may output current in a wide range up to 4 A. It can easily operate a high power application constantly when the heat sink is mounted, provided that a cooling fan is used on the heat sink to maintain continuous high power output.

The module is especially well-suited for LED driver applications since it is constructed using a specialised benchmark integrated circuit and a high-precision current sensing resistor, which prove a more stable constant current (from 20°C to 100°C constant current 1A, temperature drift less than 1%). The module’s output current can be increased to 4A.

Four high-frequency capacitances are used to improve output voltage stabilisation, resulting in a smaller output ripple. Heat dissipation is simple and quick with the double heat sink design. MOS Schottky diode independent heat sink, which has good heat dissipation and is not mutually exclusive. Additionally, to increase productivity and lower fever, double-stranded pure copper wiring and a big Sendust core are used.

3296 multiturn potentiometers are built into the module to regulate voltage and current with excellent accuracy and stability. Because the voltage and current of this module can be adjusted, it can be used for a variety of purposes, including battery charging, LED driver power supplies, vehicle power supplies, and more. Because of its many uses and affordable price, our manufacturer finds that this module is constantly in demand.

Applications:

1. High-power LED driver.
2. Lithium battery(or lead accumulator) charge.
3. Vehicle-mounted power supply.
4. Low voltage system power supply.
5. 6V, 12V, 14V, 24V battery charge.
6. On-board laptop power supply.
7. regulated power supply.
8.Low voltage power supply system.

Note: If the module temperature exceeds 65ºC, please add a cooling fan, (It be used at room temperature without a fan)

Qualities:

• The scope of this project includes high-power LED constant current drivers, solar panels, wind generators, and rechargeable lithium batteries with voltages of 4V, 6V, 12V, 14V, and 24V.
• Operating temperature range: -40 to +85 degrees Celsius (please take attention of the power tube temperature in practice; it is too high; increase heat dissipation).
