400W 15A DC-DC Step Up Boost Buck Voltage Converter Power Supply Module

Description This is a great 400W DC to DC step-up power supply module for electric equipment, digital products, laptop, etc. Input and output are designed with screw terminals for convenient wire connection and disconnection. High efficiency, the maximum conversion efficiency can be 96% and efficiency is related to input/output voltage, current and voltage difference. There are 2 heat sinks that would ensure a better heat dissipation. It can also be used as a driver for high power LED lights or voltage regulator for solar panels. Applications: DIY adjustable output vehicle power supply. Provide 12V input, the output voltage can be continuously adjusted from 14V to 35V (output voltage cannot be lower than the input voltage). Universal car laptop power supply. Provide 12V input, the output voltage is adjustable to your notebook to work. Can easily drive dual-core or quad-core notebooks at 19V and up to 6A output current. Boost Charger, to convert your car’s 12V power to greater than 12V, such as 18V or 24V Power supply for your electronic devices, as long as the voltage is adjusted to the voltage and does not exceed the module’s rated current. Output Voltage/Current Adjustment: 1. Adjust “CV-ADJ” potentiometer clockwise to reduce voltage, counterclockwise to increase voltage. 2. Adjust “CC-ADJ” potentiometer counterclockwise about 30 circles to minimize the output current before connecting to load(clockwise to increase current, counterclockwise to reduce current). Then adjust “CC-ADJ” clockwise to the current value you need. If you use the module for battery charging, connect to output after battery is fully discharged. Because if the more energy is left in battery, the less charging current will be.
