The 12V 2A Power Adapter is a dedicated power supply designed for Optical Network Units (ONUs) and other networking equipment commonly used in Fiber to the Home (FTTH) installations. It provides clean, regulated DC power to keep your internet connection stable and reliable.

Key Features

Universal Compatibility
This adapter is specifically designed to work with most ONU/ONT devices, GPON/EPON modems, routers, and popular mini UPS systems like WGP and SKE brands . Many ONU devices are rated for 12V operation with power consumption typically under 6W to 24W, making this 2A (24W) adapter more than sufficient for standard units .

Standard Connector
The adapter features the industry-standard 5.5mm x 2.1mm DC barrel connector with center positive polarity . This is the most common power connector for networking equipment, ensuring broad compatibility with devices from various manufacturers.

Safety & Efficiency
Built-in safety protections include Over Voltage Protection (OVP), Over Current Protection (OCP), Short Circuit Protection (SCP), and Over Temperature Protection (OTP) . The Level VI energy efficiency rating means lower standby power consumption and reduced electricity costs compared to older adapter designs.

Wide Input Range
With universal AC input (100-240V, 50/60Hz), the adapter works reliably in any country without needing a voltage converter .

Common Applications

Power Requirement Notes

Minimum Requirement: Most standard ONU devices require 12V at 0.5A to 1A . A 2A adapter provides ample spare capacity.

Compatibility Rule: When replacing an adapter, the voltage must match exactly (12V), while the amperage can be equal or higher than the original. Using a 2A adapter for a device that needs 1A is perfectly safe—the device only draws what it needs .

Mini UPS Charging: Many mini UPS systems for routers and ONUs specifically require a 12V 2A or 3A charger for proper charging .
