FAQ
1 What are the basic specifications of this 1200W 20A Boost Power Supply Module
It is a non-isolated DC-DC boost module with a peak power of 1200 watts and a maximum input current of 20 amps. Its DC input range is 10 to 36 volts and its DC output range is continuously adjustable from 12 to 80 volts.
2 What are the input and output voltage ranges respectively
The DC input voltage range is 10 to 36 volts and the DC output voltage range is 12 to 80 volts supporting a wide voltage adjustment capability for versatile applications.
3 What factors affect the actual output current and power
The output current can reach a maximum of 20 amps but enhanced cooling is required when the output current continuously exceeds 18 amps. The output power is equal to the input voltage multiplied by the input current and a larger voltage difference will result in a smaller available output current.
4 What are the conversion efficiency and cooling design
The maximum conversion efficiency is up to 95 percent. The module features an extra large 85 by 62 by 64 millimeter aluminum heatsink with a black oxidation surface treatment for improved heat dissipation and includes a fan connector for adding a cooling fan when needed.
5 What safety protection features does it have
It features overcurrent protection with a current limiting function adjustable down to 5 amps double short circuit protection with a replaceable 20A car fuse and output anti backflow protection. Please note that there is no input reverse polarity protection and a diode must be connected in series at the positive input terminal if needed.
6 How to correctly adjust the output voltage and current
Adjust the output voltage by operating the CV potentiometer. For current adjustment first turn the CC potentiometer counterclockwise about 30 turns to the minimum then connect the load and slowly turn it clockwise to reach the desired current value. Turning clockwise increases the value and turning counterclockwise decreases it.
7 What are the forbidden operations and electrical limits
It is strictly forbidden to adjust the current by short circuiting the output. The module is for boosting voltage only and must never be used to power loads requiring a voltage lower than the input voltage. The minimum voltage difference between the input and output must be at least 3 volts.
8 What application scenarios is this 1200W 20A Boost Power Supply Module suitable for
It is suitable for DIY regulated power supplies car laptop power supplies DIY high power mobile power supplies solar panel voltage stabilization battery charging and high power LED driving applications.
9 What special precautions should be taken when charging batteries
When setting the charging current for a battery you must use a fully discharged battery for calibration because a higher remaining battery charge results in a lower actual charging current. The module features output anti backflow protection so no additional diode is needed for charging.
10 What are the core components and design features of this 1200W 20A Boost Power Supply Module
It utilizes a 27 millimeter large iron silicon aluminum magnetic ring with dual parallel windings of extra thick all copper enameled wire to minimize heat. It employs two 470uF/100V input capacitors and three 470uF/100V low impedance output capacitors to significantly reduce output ripple. The vertical inductor design effectively reduces interference making the overall circuit robust and reliable.
