Sell DC Step Down 12A Adjustable voltage and Current buck converter best price

Module properties: non isolated constant current, constant voltage (CV CC) module Input voltage: 7-32V Output voltage: continuous adjustable (0.8-28V) 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). Lowest Output: 1V Output power: the maximum power of about 300W Conversion efficiency: up to 95% (the higher the output voltage, the higher the efficiency). Working frequency: 300KHZ Output ripple: 20M bandwidth Input 24V output 5A 50mV ripple 12V around (no noise) Working temperature: industrial grade (-40 to +85) No-load current: typical 20mA (24V to 12V) Load adjustment rate: 1% (constant pressure) Voltage adjustment rate: 1% 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. Features: 1. 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°C to 100°C constant current 1A, temperature drift less than 1%). Particularly suitable for LED driver. 3. High output current, the max output current can reach 8A. 4. Four high frequency capacitance, can lower output ripple, enhance the work stabilization. 5. Double heat sink design. MOS schottky diode independent heat sink,which heat dissipation is good, and won't affect each other. 6. Using large size Sendust Core and double pure copper wiring, improve working efficiency, reduce fever. 7. 3296 multiturn potentiometer,high accuracy voltage and current regulation, good stability. 8. Double color lamp, working condition be clear at a glance 9. Voltage and current are adjustable,wich effect is good.
