Description
Module properties: synchronous rectification, non-isolated buck, 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, NiCd NiMH battery (battery pack) charging, solar panels, wind turbines
Input voltage: DC6-40V
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: maximum 20A within 15A for a long time (please add a fan for heat dissipation if the temperature of the power tube exceeds 65 degrees, and use derating for high voltage output)
Current limiting range: 0.2-20A (adjustment) If the module exceeds 65 degrees, please add a fan.
Minimum dropout voltage: 3V
Working frequency: 150KHZ
Conversion efficiency: up to about 96% The efficiency is related to the pressure difference and the use environment
Output ripple: about 50mV ripple (no noise) 20M bandwidth (for reference only) input 24V measured
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 the heat dissipation or derate the use)
Potentiometer adjustment direction: clockwise (increase), counterclockwise (decrease)
Output short-circuit protection: yes (instantaneous protection) constant current (currently set constant current value cannot be short-circuited for a long time)
Input reverse polarity protection: none,
Output anti-backflow: none, for self-charged or inductive loads, an external 2-pole tube is required!
Wiring method: terminal block
Module size: 60*53*30MM
Net weight: about 85 grams
