300W DC-DC Step Down Buck Converter 5-40V To 1.2 -35V Max 12A Adjustable Power Supply Module Short Circuit Protection for Arduino
Specification:
Origin: Mainland China
Type: Module
Condition: New
Module nature: Non isolated step-down constant current and constant voltage module (CC CV) charging module
Scope of application: high-power LED constant current drive, lithium battery charging (including ferroelectric), 4V, 6V, 12V, 14V, 24V battery charging, nickel cadmium nickel hydrogen battery (battery pack) charging, solar panels, wind turbines
Input voltage: 7-32V (without constant current 5-32V)
Output voltage: continuously adjustable ( 0.8 -28V)
Output current: Maximum 12A (If the temperature of the power tube exceeds 65 degrees, please add a fan for heat dissipation. Generally, no fan can be added in open environments within 6A from 24V to 12V)
Constant current range: 0.2 -12A (adjustable) (not available with constant current)
Rotating lamp current: constant current value * ( 0.1 ), the rotating lamp current is linked to the constant current value. For example, if the constant current value is 3A, the rotating lamp current is set to 0.1 times the constant current ( 0.1 * 3A= 0.3A ). When the constant current value is adjusted to 2A, the rotating lamp current is 0.1 times the constant current ( 0.1 * 2A= 0.2A )
The secondary version is fixed at 0.1 times (the actual lamp current is not very accurate) for indicating whether the charging is fully charged.
Lowest pressure difference: 1V
Output power: The maximum power is about 300W. If the temperature of the power tube exceeds 65 degrees, please add a fan.
Conversion efficiency: Up to about 95% (the higher the output voltage, the higher the efficiency)
Working frequency: 300KHZ
Output ripple: 20M bandwidth (for reference only)
Working temperature: Industrial grade (-40 to+85 ) (please pay attention to the temperature of the power tube in actual use, and if the temperature is too high, please strengthen heat dissipation)
No-load current: typical 20mA (24V to 12V)
Load adjustment rate: 1% (constant voltage)
Voltage regulation rate: 1%
Constant current accuracy and temperature: In actual testing, the temperature on the module changes from 25 degrees to 60 degrees, and the change in constant current value is less than 5% (constant current value 5A)
Dynamic response speed: 5% 200uS
Adjustment direction of potentiometer: clockwise (increase), counterclockwise (decrease) potentiometer close to input is voltage regulation (CV), and potentiometer close to output is current regulation (CC)
Indicator light: Dual color indicator light, red indicator light during charging, green indicator light after charging (green when not connected to load), red indicator light without constant current.
Typical applications: adjustable power supply (12A power is large enough), high-power LED driver, LED display screen driver, leading-acid battery charging, lithium battery charging, car power supply, car laptop power supply (step-down), regulated power supply, low-voltage system power supply, (such as reducing the voltage of 12V battery for children's toy cars to 6V), 24V to 12V 12A 12V to 5V 12A 24V to 5V 12A 24V to 19V20V, etc., with a wide range of applications.
Size: 65 * 47 * 23.5 mm/ 2.56 * 1.85 * 0.93 in
Weight: 52g
Note:
Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
Please allow 1-2cm measuring deviation due to manual measurement.
