HOW TO SELECT AN AC/DC POWER ADAPTER

Follow these simple steps to choose the right power adapter for your devices

STEP1
Voltage Requirement

Define the output voltage required by your equipment, such as 5V, 12V, 19V, 24V or 48V.

STEP2
Current Requirement

Check the maximum current consumption of the device to ensure stable operation.

STEP3
Power Calculation

Power is calculated using the formula: Power (W) = Voltage × Current Example: 12V × 5A = 60W

STEP4
Connector Type

Select the appropriate DC connector or cable interface such as: 5.5×2.1mm 5.5×2.5mm USB-C

STEP5
Input & Plug Type

Ensure compatibility with regional AC plug standards: EU Plug US Plug UK Plug AU Plug

STEP6
Certification Requirements

Select certifications based on target market: CE (Europe) UL (North America) FCC (EMC compliance) CB (international safety)
