DC 6-40V To 1.2-36V 300W 20A Constant Current Adjustable Buck Converter Step Down Module Board With Short Circuit Protection Function
Module parameters
Input voltage 6-40V
Module nature: Synchronous rectification non isolated step-down constant current 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: 6-40VDC
Output voltage: continuously adjustable (1.2-35VDC) for a long time below 32V (suitable for applications where the input voltage is higher than the output voltage and cannot be boosted)
Output current: Within 15A for a long time, with a maximum output of 20A (if the temperature of the power transistor exceeds 65 degrees, please add a fan for heat dissipation, and for high voltage output, please reduce the rating for use)
Current limiting range: 0.2-20A (adjustable). If the module exceeds 65 degrees, please add a fan.
Zui low pressure difference: 3V
Working frequency: 150KHZ
Conversion efficiency: ZUI is about 96% higher, and the efficiency is related to pressure difference and usage environment
Output ripple: ripple around 50mV (excluding noise), 20M bandwidth (for reference only), measured at 24V input
Working temperature: -10 ℃ to+75 ℃) (Please pay attention to the temperature of the power tube during actual use. If the temperature is too high, please strengthen heat dissipation or reduce the rating for use)
Direction of potentiometer adjustment: clockwise (increase), counterclockwise (decrease)
Output short-circuit protection: with (instantaneous protection) constant current (the current set constant current value cannot be short circuited for a long time)
Input reverse protection: none,
Output anti backflow: None, used for self powered loads or inductive loads that require an additional 2-pole transistor!
Wiring method: Wiring terminals
Module size: 60 * 53 * 30MM
