DC/CC Adjustable Power Supply Module 7-32V To 0.8-28V LED Driver Module with Charging Indicator Voltage Regulator Board

DC/CC Adjustable Buck Converter 7-32V To 0.8 -28V LED Driver Module with Charging Indicator Voltage Regulator Board 0.2 - 12A 300W
Specification:
Origin: Mainland China
Type: Voltage Regulator
Condition: New
Model Number: Step Down Converter
Module Parameters
Module nature: non-isolated buck constant current, 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-metal hydride batteries (battery packs) charging, solar panels, wind generators
Input voltage: 7-32V
Output voltage: continuously adjustable ( 0.8 -28V)
Output current: 12A (power tube temperature exceeds 65 degrees, please add a fan cooling, 24V to 12V 6A or less in the open environment generally can not add a fan)
Constant current range: 0.2 -12A (adjustable)
Turn lamp current: constant current value * ( 0.1 ), turn lamp current and constant current value linkage, such as constant current value of 3A, turn lamp current is set to constant current 0.1 times ( 0.1 * 3A = 0.3A ), when the constant current value is adjusted to 2A, this time the turn lamp current for the constant current of 0.1 times ( 0.1 * 2A = 0.2A ).
The second version is fixed 0.1 times (the actual turn lamp current is the approximate value is not very) for charging whether full indication.
Is low voltage difference: 1V
Output power: is high power about 300W, power tube temperature over 65 degrees, please add a fan.
Conversion efficiency: is high about 95% (the higher the output voltage, the higher the efficiency)
Operating frequency: 300KHZ
Output ripple: 20M bandwidth (for reference only)
Input 24V output 12V ripple 50mV or so (excluding noise)
Operating temperature: industrial grade (-40 C to +85 C) (the actual use of the power tube temperature, the temperature is too high, please strengthen the heat dissipation)
No-load current: typical 20mA (24V to 12V)
Load adjustment rate: 1% (constant voltage)
Voltage adjustment rate: 1%
Constant current accuracy and temperature: actual test, the module on the temperature change from 25 degrees to 60 degrees, constant current value change is less than 5% (constant current value)
Dynamic response speed: 5% 200uS
Direction of potentiometer adjustment: clockwise (increase), counterclockwise (decrease) The potentiometer close to the input is for voltage adjustment (CV), and the potentiometer close to the output is for current adjustment (CC).
Indicator light: two-colour indicator light, red during charging, green after charging (green without load), red without constant current.
Output short circuit protection: Yes
Input reverse connection protection: No
Output reverse current: no
Wiring: terminal
Product size: 65x45x20mm/ 2.56 x 1.77 x 0.79 inch
Weight: 57g
Battery charging Method of use:
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.
