PCBA DC-DC CC CV Buck Converter Step-down Power Module 7-32V to 0.8-28V 12A 300W
Product Description
. Fixed turn lamp current is 0.1 times the current value ( Used to identify whether the battery is fully charged When charging). 2. Made from a dedicated benchmark IC and high-precision current sensing resistor, proving a more stable constant current, (when 20℃ to 100℃ constant current 1A, temperature drift less than 1%). Particularly suitable for LED driver. 3. High output current, the max output current can reach 12A. 4. Four high frequency capacitance, can lower output ripple, enhance the work stabilization. 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 Package included： 1 x DC buck converter module 12A Note:Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
Module parameter
Module Properties: Non - isolated Buck Constant Current and Constant Voltage Module ( CC CV ) Charging Module
Scope of application: high power led constant current drive, lithium battery charging ( including ferroelectricity ), 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 ) Now the latest input voltage is 40V
Output voltage: ( 1 ) continuously adjustable ( 0.8 - 28V ) latest output voltage ( 1.2 - 35V )
( 2 ) Fixed output ( any choice between 0.8 - 28V ), please tell the shopkeeper when buying. ( For batch customers only, all samples are adjustable for the time being )
( 3 ) If you need a higher voltage, please contact me directly
Output current: max. 12a ( latest output current 8 - 9a ) ( please add fan to dissipate heat when the temperature of power pipe exceeds 65 degrees, and generally no fan can be added to open environment within 24v to 12v 6a )
Constant current range: 0.2 - 12a ( adjustable ) ( no such function without constant current ) ( latest output current 8 - 9a )
Turn lamp current: constant current value * ( 0.1 ), turn lamp current is linked with constant current value, for example, constant current value is 3a, turn lamp current is set to 0.1 times constant current ( 0.1 * 3a = 0.3a ), when constant current value is adjusted to 2a, turn lamp current is 0.1 times constant current ( 0.1 * 2a = 0.2a ).
The second version is 0.1 times the fixed value ( the actual lamp current is approximate value is not very accurate ) and is used to indicate whether the charge is full or not.
Lowest pressure difference: 1V
Output power: The maximum power is about 300 W, please add fans when the temperature of the power tube exceeds 65 degrees.
Conversion efficiency: up to about 95 % ( the higher the output voltage, the higher the efficiency )
Operating frequency: 300 kHz ( latest frequency: 180 kHz )
Output ripple: 20m bandwidth ( for reference only )
Input 24V Output 12V 5A Ripple About 50MV ( No Noise )
Operating temperature: industrial level ( - 40 ℃ to + 85 ℃ ) ( please pay attention to the temperature of power tube in actual use, and strengthen heat dissipation if the temperature is too high )
No - load current: typical 20mA ( 24V to 12V )
Load adjustment rate: 1 % ( constant voltage )
Voltage adjustment rate: 1 %
Constant current precision and temperature: actual test shows that the temperature on the module changes from 25 degrees to 60 degrees, and the constant current value changes less than 5 % ( constant current value 5a )
Dynamic Response Speed: 5 % 200 US
Potentiometer adjustment direction: clockwise ( increase ), counterclockwise ( decrease ) the potentiometer close to the input is voltage adjustment ( cv ), and the potentiometer close to the output is current adjustment ( cc )
Indicator light: two-color indicator light, the indicator light during charging is red, the indicator light after charging is green ( the indicator light without constant current is green ).
Output short circuit protection: Yes, constant current ( current set constant current value )
Input Reverse Protection: None,
Output to Prevent Countercurrent: None.
Connection mode: connection termina
