Switch Series Product Collection KKG Developing with the Green Planet
The 5.5mm x 2.5mm DC Power Cable is a high-current barrel connector commonly used for powering devices like security systems, LED strips, and audio equipment. Its key feature is a robust 18A current rating, making it ideal for high-power applications. The larger 2.5mm inner pin provides a secure connection and superior conductivity compared to standard 2.1mm versions. This cable ensures efficient and reliable power delivery with minimal voltage drop over distance.
Canon PIXMA 2.5mm DC Power Cable's Product Operating Principle
This cable transmits direct current (DC) power through its central positive conductor and outer negative sleeve. The 5.5x2.5mm barrel connector ensures a secure and reliable connection between the power source and the device, minimizing energy loss.

Q: What is the maximum current for this 5.5mm x 2.5mm DC cable?
A: This cable is specifically rated for a maximum current of 18 amps (18A), making it suitable for high-power devices.
Q: Is the 5.5mm x 2.5mm connector size important?
A: Yes. The 5.5mm outer diameter and 2.5mm inner pin must match your device's DC jack for a secure, correct connection.
Q: What applications require an 18A power cable?
A: It is ideal for powering high-demand equipment like professional amplifiers, powerful PoE switches, and large LED arrays.
Q: Can this cable handle higher voltages?
A: While current is 18A, always check its voltage rating (e.g., 12V/24V DC) to ensure compatibility with your power supply.
Q: Why use a heavy-duty DC power connector?
A: The robust 5.5mm/2.5mm size and 18A rating ensure minimal power loss and heat generation under high electrical loads.
