Note:
Please allow 1-3mm differs due to manual measurement.
Due to the different display and different light, the picture may not reflect the actual color of the item. Thanks for your understanding.
Specification:
Input Voltage: DC 6V to 40V (10V to 40V is suggested)
Output Voltage: Continuously adjustable(1.2V to 35VDC) Long time below 32V (applicable to applications where the input voltage is higher than the output voltage cannot be boosted)
Output Current: 20A(max.), Within 15A for a long time (please add a fan to dissipate the heat if the temperature of the power tube exceeds 65 degrees, please derate it for high voltage output)
Current limit range: 0.2-20A (adjustment) module exceeds 65 degrees, please add a fan.
Minimum pressure difference: 3V
Working frequency: 150KHZ
Conversion efficiency: Up to about 96% efficiency is related to pressure difference and use environment
Output ripple: Ripple is about 50mV (no noise included) 20M bandwidth (for reference only) input 24V measured
Working temperature: -10 ℃ to + 75 ℃) (Please pay attention to the power tube temperature in actual use, if the temperature is too high, please strengthen the heat dissipation or derating)
Potentiometer adjustment direction: clockwise (increasing), counterclockwise (decreasing)
Output short circuit protection: Yes (instantaneous protection) constant current (currently set constant current value cannot be short-circuited for a long time)
Input reverse connection protection: none,
Output anti-backflow: No, for load self-charged or inductive load requires 2 extra tubes!
Wiring method: terminal
Size: About 60 x 53 x 27mm / 2.36 x 2.08 x 1.06"
VO+: Output positive
VO-: Output negative
+IN: Input positive
-IN: Input negative
CV: Output voltage adjustment
CC: Output current adjustment
EN: Enable, low voltage level shut off output; suspension, high voltage level is effective
When input and output is common grounded, no-load CV output constant voltage,CC output constant current
Feature:
With a wide input voltage range from 6V to 40V, the step-down converter can accurately adjust output voltage and current.
The efficiency can be up to 96%, measured at 20A, converting 24V to 12V.
It is designed with 75V/80A large current dual MOS tube.
Input and output use high frequency low resistance electrolytic capacitor, low ripple, stable output.
Wiring is convenient with these large current 30A screw terminals.
The buck module has 2 heat sink that could enhance heat dissipation.
When there is a big difference between input and output voltage, please decrease power and current.
