300W 10A DC-DC Step Down Buck Converter Input 7-40V to Output 1.2-35V Module

300W 10A DC-DC Step Down Buck Converter Input 5-40V to Output 1.2-35V Module is an adjustable +1.2 to 35vdc output, 10A current capacity. It is ideal for battery operated projects requiring a higher current regulated power supply.

The 10A 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 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).

Features:

• Fixed lamp current is 0.1 times of constant current value (used to identify whether the battery is full when charging);
• A dedicated reference IC and a high-precision sampling resistor are used to make the constant current more stable (the temperature drift is less than 5% at a constant current of 5 degrees from 20 degrees to 60 degrees). Particularly suitable for LED drivers
• The output current is large, and the maximum output current can reach 10A, which meets most needs.
• 4 high frequency capacitors to effectively reduce output ripple and improve working stability
• Double heat sink design, MOS tube Schottky diode independent heat sink, good heat dissipation, mutual influence
• At the cost, the large-size iron-silicon-aluminum magnetic ring is used to improve the working efficiency, and the pure copper double wire is used to reduce heat and improve efficiency.
• 3296 multi-turn potentiometer, high voltage and current regulation accuracy, good stability.
• Dedicated current sampling resistor The current sampling precision is high, the stability is good, and the temperature is small. LED is a must.
• Two-color indicator light, the working status is clear at a glance. Rechargeable.
• The voltage and current are all adjustable, and the adjustable power supply is good. The 10A current is large and the power is sufficient.
