KEHIPI

KEHIPI 12V-24V to 5V 3A 15W Step-Down Power Adapter

SKU CH-CPV9-0KP2J

Converts 12V-24V DC input to a stable 5V 3A 15W output with over 90% efficiency and automatic protection against over-voltage, over-current, over-temperature and short circuits

  • Converts 12V-24V input to stable 5V 3A output
  • Over 90% conversion efficiency reduces energy waste
  • Four protection circuits guard against voltage, current, heat and shorts
  • Automatic recovery restores operation after fault conditions clear
  • Suited for automotive, surveillance, railway and LED installations

DC 12V-24V to 5V 3A Step-Down Converter

This KEHIPI power adapter converts an unstable 12V to 24V DC input into a regulated 5V DC output rated at 3A and 15W. It is intended for installers and hobbyists who need to run 5V devices such as LED strips, car audio modules or surveillance cameras from a higher-voltage vehicle or industrial supply.

Over 90 percent efficiency

The module delivers over 90 percent conversion efficiency and integrates over-voltage, over-current, over-temperature and short-circuit protection that automatically resets once the fault clears. A maximum working temperature of 80 °C is specified, though the supplier notes that output should be reduced or extra heat dissipation added when ambient temperature exceeds 45 °C.

Verify your source voltage and load before ordering

Confirm that your supply stays within the 12V to 24V DC input range and that the connected equipment draws no more than 3A at 5V. The unit is supplied as a bare regulator module without an enclosure, so plan for suitable mounting and ventilation in the final installation.

Questions about this item

What input-voltage range does the step-down converter accept, and what is the maximum continuous output it can deliver?

It accepts 12 V to 24 V DC and provides a regulated 5 V DC output at up to 3 A, for a maximum of 15 W continuous power.

What mounting or wiring provisions does the module have for installation in a vehicle or enclosure?

The unit is a bare PCB module with solder-pad or screw-terminal connections for input and output; it has no dedicated mounting holes or brackets, so you must secure it with adhesive, ties or a custom bracket.

How do you wire the converter, and what common mistake causes it to overheat or shut down?

Connect the 12 V–24 V source to the input terminals observing polarity, then attach the 5 V load to the output terminals; the frequent error is running near 15 W in ambient temperatures above 45 °C without adding a heatsink or airflow, which triggers thermal protection.
