Module properties: synchronous rectification, non-isolated step-down, constant current and 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-hydrogen battery (battery pack) charging, solar panels, wind turbines Input voltage: DC12-35V Output voltage: Continuously adjustable (1.2-32VDC) below 32V for a long time (suitable for applications where the input voltage is higher than the output voltage and cannot be boosted) Output current: Maximum 20A, 15A for a long time (please add a fan for cooling if the power tube temperature exceeds 65 degrees, please derate the high voltage output) Parameter Description: Current limiting range: 0.2-20A (adjustable) If the module exceeds 65 degrees, please add a fan. Minimum voltage drop: 3V Working frequency: 150KHZ Conversion efficiency: up to about 96%. The efficiency is related to the pressure difference and the use environment. Output ripple: Ripple is about 50mV (excluding noise) 20M bandwidth (for reference only) measured with 24V input Working temperature: -10℃ to +75℃) (Please pay attention to the temperature of the power tube in actual use. If the temperature is too high, please strengthen heat dissipation or derate the use) Potentiometer adjustment direction: clockwise (increase), counterclockwise (decrease) Output short-circuit protection: Yes (instantaneous protection) constant current (the current set constant current value cannot be short-circuited for a long time) Input reverse polarity protection: None, Output anti-reverse flow: None, if the load is self-charged or inductive, an additional 2-pole transistor is required! Wiring method: terminal block Mo Material: plastic+metal colour: As Shown Package Contents: 1 x module Only the above package content, other products are not included.
