Buck Converter Step-Down
300W 20A DC-DC Buck Converter Step-down Module Constant Current LED Driver Module
Buck Converter Step-Down300W 20A DC-DC Buck Converter Step-down Module Constant Current LED Driver Module
Product Highlights :
Features of 300W 20A DC-DC Buck Converter Step-down Module Constant Current LED Driver Module :
- Scope: High-power LED constant current driver, rechargeable lithium batteries 4V, 6V, 12V, 14V, 24V battery charging; nickel-cadmium nickel-metal hydride batteries (battery) charging, solar panels, wind generators.
- Output voltage: continuously adjustable (1.25-36V) (applied to the input voltage is higher than the output voltage applications can boost).
- Turn lights Current: current value * (0.1), turn the lamp current, and constant value linkage, such as the constant value of 3A.
- Turn the lamp current is set to a constant current of 0.1 times (0.1 x 3A = 0.3A), when the constant 2A, when adjusted to the current value, then turn the lamp current constant current of 0.1 times (0.1 x 2A = 0.2A).
- This version is a fixed 0.1 times (actually turn the lamp current value is probably not very accurate) is full of instructions for charging.
- Minimum pressure: 1V.
- Output Ripple: about the ripple 50mV (without noise) 20M bandwidth (for reference) Input 24V Output 12V 5A measured.
- Operating temperature: -10 to + 75 (please note the actual use of the power tube temperature, the temperature is too high, please enhance heat dissipation).
