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

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.

• Type: Non-isolated boost module
• Input Voltage: DC8.5V to 50V
• Output Voltage: DC10V to 60V (continuously adjustable, default 19V)
• Max. Input Current: 15A (enhance heat dissipation if more than 8A)
• Max. Output Current: 12A (related to the input and output voltage difference, the greater voltage difference is, the smaller output current will be. please enhance heat dissipation when current is over 7A)
• Quiescent Current: 10mA(will increase when convert 12V to 20V)
• Constant Current Range: 0.2A to 12A
• Output Power = Input Voltage*Current
• Operating Temperature: -40℃ to 85℃(if temperature is too high, please enhance heat dissipation)
• Frequency: 150KHz
• Max. Conversion Efficiency: 96% (Efficiency is related to input/output voltage, current and voltage difference)
• Over Current Protection: Yes (if input current is more than 15A, it will automatic reduce output voltage)
• Reverse Input Protection: No
• Size: 67 x 48 x 28mm / 2.63 x 1.89 x 1.1"

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.
