Description
Feature:
1: Made of high quality material, more durable.
2: Electrolytic capacitor high frequency of low resistance, Low resistance, ?stable output.
3: Module properties: synchronous rectification, non-isolated buck, constant current and constant voltage module, CC CV charging module.
4: Scope of application: high-power LED constant current drive, lithium battery charging (including ferroelectric), 4V, 6V, 12V, 14V, 24V battery charging,
Ni-Cd Ni-MH battery (battery pack) charging, solar panels, wind turbines.
Output current adjustment method:
1. Adjust the CV potentiometer and set the output voltage to the voltage value you need according to your load requirements.
2. Set the CC potentiometer counterclockwise about 30 turns (that is, set the output current to the minimum), connect the LED, and adjust the CC potentiometer to the current you need.
For battery charging, after the battery is fully discharged, connect it to the output, and adjust the CC to the current you need. The more, the smaller the charging current.)
Specifics:
Condition: 100% Brand New
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
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 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*30 mm/2.36*2.09*1.18 in
Wiring Instructions:
OUT+: output positive
OUT-: output negative
+IN: input positive
-IN: Enter a negative number
CV: Output Voltage Regulation
CC: output current regulation
EN: Enable, low level closes output; Pause, high voltage level active
When the input and output are grounded, no-load CV output constant voltage, CC output constant current
Note:
1.Please allow 1-3mm difference due to manual measurement.
2.Item color displayed in photos may be showing slightly different on your computer monitor since monitors are not calibrated same.
