About DUTTY Rectifier Step-Down Constant Voltage Constant
Product parameters: 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: 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: maximum 20A, within 15A for a long time (please add a fan to dissipate heat 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. Low dropout: 3V Working frequency: 150KHZ Conversion efficiency: about 96% higher, 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 Products include 20A step-down constant voltage constant current power supply module *1
