Typical application:
Adjustable power supply (12A power is large), high power LED driver, LED display driver, lead battery charging, lithium battery charging, car power supply, power supply, power supply, (for example, children\\\'s toy car with 12V battery 6V 5V 12V 12A \\\\12V 24V 12A \\\\24V 12A \\\\24V 19V20V etc., the application range is very wide.
One Fixed turn lamp current is 0.1 times of the constant current value (charge) for the identification of whether the battery is full);
Two Using a dedicated benchmark IC, and high accuracy of the sampling resistor, so that constant current is more stable, (20 degrees to 60 degrees constant current 5A when the temperature is less than 5%). Especially suitable for LED driver
3 output current is large, the maximum output current can reach 12A, meet most of the needs.
4.4 high frequency capacitor, effectively reduce the output ripple, improve the working stability
5 pairs of heat sink design, MOS tube Schottky diode independent heat sink, good heat dissipation, mutual influence
6. Regardless of the cost by using large size sendust core, improve work efficiency, and copper wire and Rao, reducing fever and improve the efficiency.
Seven 3296 multi ring potentiometer, voltage and current regulator with high accuracy, good stability.
8 special current sampling resistor current sampling precision is good, the temperature is small. LED necessary.
9 double color indicator light, working status at a glance. Charge must.
10 voltage and current can be adjusted to do good, 12A current, power is enough.
Module parameter
Module properties: non isolated constant current, constant voltage (CV CC) module
Scope of application: high power LED constant current drive, rechargeable lithium batteries (including ferroelectric), 4V, 6V, 12V, 14V, 24V battery, rechargeable NiCd and NiMH batteries (batteries), solar panels, wind generator
Input voltage: 7-32V (not 5-32V)
Output voltage: (1) continuous adjustable (0.8-28V)
(2) fixed output (0.8-28V choose any), please tell the shopkeeper to buy. (for the time being only for the bulk of the customer, the sample can be all made adjustable).
(3) please contact me directly if you need a higher voltage.
Output current: the maximum 12A (power tube temperature of more than 65 degrees, please add the fan cooling, 24V to 6A 12V in the open environment can generally be no fan)
Constant current range: 0.2-12A (adjustable) (without the constant flow of this function)
Turn light current: constant current value * (0.1), turn the lamp current and constant current value linkage, such as constant current value is 3A, turn the lamp current is set to 0.1 times (0.1*3A=0.3A), when the constant current value is adjusted to 2A, then turn the lamp current is 0.1 times (0.1*2A=0.2A).
The second version is fixed 0.1 times (the actual lamp current is the value is not very accurate) for charging whether full instructions.
The most low pressure difference: 1V
Output power: the maximum power of about 300W, power tube temperature of more than 65 degrees, please add a fan.
Conversion efficiency: up to 95% (the higher the output voltage, the higher the efficiency).
Working frequency: 300KHZ
Output ripple: 20M bandwidth (for reference only)
Input 24V output 5A 50mV ripple 12V around (no noise)
Working temperature: industrial grade (-40 to +85) (the actual use please note that the temperature of the tube, the temperature is too high, please strengthen the heat dissipation)
No-load current: typical 20mA (24V to 12V)
Load adjustment rate: 1% (constant pressure)
Voltage adjustment rate: 1%
Constant current accuracy and temperature: the actual test, the module temperature from 25 degrees to 60 degrees, constant current value of less than 5% (constant current value 5A)
Dynamic response speed: 5% 200uS
Potentiometer adjustment direction: clockwise (increase), counter clockwise (reduce) near the input potentiometer for voltage regulation (CV), close to the output of the potentiometer for the current regulation (CC)
Indicator: two color indicator, charging indicator light red, charging indicator light green (not to take the load for the green) without a constant flow of the indicator light is red.
Output short circuit protection: there is a constant current (current setting constant current value)
Input back protection: no,
Output to prevent adverse current: No.
Connection mode: terminal
Battery charging method:
1 you need to determine the floating voltage of the rechargeable battery and the charging current, input voltage module;
2 adjust the constant voltage potentiometer, the output voltage regulation to about 5V.
3 with the use of the 10A current meter to measure the output short-circuit current, at the same time to adjust the constant current potentiometer to the output current to achieve a predetermined charge current value;
4 to adjust the output voltage of the constant voltage potentiometer to float voltage;
5 battery, test charge.
(1, 2, 3, 4 step for the module input power, output no-load battery.)
LED constant current drive method:
1 determine the operating current and the maximum operating voltage you need to drive LED;
2 adjust the constant voltage potentiometer, the output voltage regulation to about 5V.
3 with the use of the 10A meter current block to measure the output short-circuit current, while adjusting the constant current potentiometer to make the output current to reach a predetermined LED operating current;
4 adjust the voltage potentiometer to make the output voltage to reach the highest operating voltage of LED;
5 LED, test machine.
(1, 2, 3, 4 step for the module input power, output no-load LED lamp.
