TL494 - 400W 15A DC-DC Step-up Constant Current Power Supply

Features:

This is a great 400W DC to DC step-up power supply module. 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.

Specifications: 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).
  3. Then adjust "CC-ADJ" clockwise to the current value you need.
Note: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.
