20A 300W High Power CV/CC Power Module

Module Parameters:

● Input voltage 6-40V

● Module nature: Synchronous rectification, non isolated step-down, constant current, constant voltage module, CC CV charging module

● Applicable scope: 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: 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 period of time, it is greater than 20A (if the temperature of the power tube 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.

● Minimum pressure difference: 3V

● Operating frequency: 150KHZ

● Conversion efficiency: The highest efficiency is about 96%, which is related to pressure difference and usage environment

● Output ripple: ripple is about 50mV (excluding noise), with a bandwidth of 20M (for reference only), measured at 24V input

● Operating 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 reduce the rating for use)

● Adjustment direction of potentiometer: 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 load self charging or inductive loads that require an additional 2-pole transistor!

● Wiring method: Terminal blocks

● Module size: 60 * 53 * 30MM
