Product Description1PCS 300W DC-DC 20A step-down module converter boost power
100% brand new and high quality
Made of high-quality materials, durable
This 300W 20A DC-DC step-down module can be used to obtain an adjustable
output voltage range from 1.2V to 36V.
The output current of the module can be increased to 20A (continuous use is
recommended to install a cooling fan to 15A).
The module has a built-in 3296 multi-turn potentiometer, which can adjust
high-precision voltage and current with good stability
High-power LED driver.
Lithium battery (or lead storage battery) is charged.
Car Power. Low-voltage system power supply. 6V, 12V, 14V, 24V battery
charger. Onboard laptop power supply. Power Supply. Low-voltage power supply
Size: about 60 x 52 x 27mm / 2.36 x 2.05 x 1.06''
Input voltage: DC 6-40V (10V to 40V recommended)
Output voltage: DC 1.2-36V
Output current: 20A (maximum), 15A (recommended)
Efficiency: 97% (24V to 12V, 20A)
Output ripple: ≤50mV
Short-circuit protection: self-recovery (cannot be short-circuited for a long
Working temperature: -10°C-70°C (add cooling 70°C when close to temperature)
Working frequency: 150kHz
Conversion efficiency: up to 96% efficiency is related to pressure difference
and use environment
Potentiometer adjustment direction: clockwise (increase), counterclockwise
Wiring mode: terminal block
OUT+: output positive
OUT-: output negative
IN: input positive
IN: Enter a negative number
CV: output voltage regulation
CC: output current adjustment
EN: enable, turn off output at low level; pause, effective at high level
When the input and output are grounded, CV outputs constant voltage without
load, and CC outputs constant current
1*300W DC-DC step-down converter
