Product Description

Marking description:

IN+: Positive terminal of the input voltage

IN-: Negative terminal of the input voltage

OUT+: Positive terminal of the output voltage

OUT-: Negative terminal of the output voltage

CV: Output voltage regulating potentiometer

FAN+:12v fan connector

ON/OF: Output voltage switch (Short circuit turns off output)

 

10-15V: Short circuit allows 10-15V input (the input voltage after short circuit must not exceed 15V).

Product features:

This product adopts mature synchronous rectification technology, generating little heat and featuring high conversion efficiency. Wide voltage input: DC15-90V, wide voltage output: DC2.5-72V, and the output voltage is continuously adjustable. Temperature-controlled fan cooling.

Note:

1.This power supply is a buck power supply, can only buck, can not boost.

2.The positive and negative terminals of the input must not be reversed.

3.This power supply is constant voltage power output current is not adjustable, not recommended for battery constant current charging and LED constant current drive.

4.When the output is connected to the motor, a Schottky diode with a current of more than 50A and 100V should be connected in series at the output positive electrode to prevent backflow. Do not use at maximum power and maximum current for a long time. Leave a margin of more than 20% when working for a long time. The power supply has maximum power and maximum current limits. When in use, do not exceed the output power and output current.

Application scenario: 

Convert high voltage to low voltage to provide stable power supply for equipment.

 

Pros & Cons

Pros

  • High 1500W/50A power capacity for heavy-duty power supply applications
  • Adjustable constant voltage and constant current output for flexible use
  • Includes onboard switch and potentiometer for easy output control
  • Includes fan connector for active cooling to prevent overheating

Cons

  • Requires an external 12V fan for optimal performance at full power load
  • No included mounting hardware or heat sink (sold separately for most users)
  • Only ships from Mainland China, leading to longer international delivery times
  • Limited input voltage range, not compatible with lower or higher voltage input systems
