Power adapter Extralink EX.14558 50W Indoor Silver 110-230V

The Extralink EX.14558 50W Indoor Silver power adapter is a compact indoor buffer power supply designed for uninterrupted DC power delivery. It accepts a wide input range of 110–230V AC and provides up to 50W of output power. The unit features an aluminum housing with a silver finish and passive cooling enhanced by perforated metal casing for improved airflow. Screw terminals are clearly marked for safe cable connections, and an adjustable potentiometer allows fine tuning of the output voltage. The adapter also supports connection of an external battery so that, in the event of mains failure, energy can be supplied from the battery to maintain continuity of the connected equipment.

Advantages

The Extralink EX.14558 combines a broad input voltage range with a reliable 50W DC output in a compact 99 × 97 × 38 mm package. Its aluminum enclosure and perforated design improve heat dissipation without requiring a fan, reducing mechanical noise and maintenance. Clearly marked screw terminals and adjustable output voltage make installation and configuration straightforward for installers. Support for an external battery provides backup capability to keep equipment running during power outages.

Suitable for

• Backup power for networking equipment such as routers and switches
• Powering CCTV cameras and low-power surveillance systems
• Small access control panels and security devices
• LED lighting modules and low-voltage electronic modules
• Any indoor DC-powered device requiring up to 50W with battery backup capability

How to use

Install the Extralink EX.14558 in a dry, ventilated indoor location where the perforated casing can receive free airflow. Connect the AC mains input to the designated screw terminals following local electrical codes, then connect the DC output to the load using the clearly marked output terminals. If battery backup is required, connect a compatible external battery to the battery terminals, observing correct polarity and recommended battery specifications. Use the onboard potentiometer to fine-tune the output voltage to match the requirements of the connected device. Verify all connections and test the system by simulating a mains failure to ensure the battery takes over the load smoothly.

Recommendations

For reliable operation, use a battery with appropriate capacity and rated voltage for the expected backup duration; ensure proper ventilation around the adapter and avoid covering the perforated casing. Follow applicable installation and safety standards when wiring mains and battery connections, and consult a qualified electrician for installations involving mains power.
