Power supply Extralink AD-155C 48V 155W Indoor Black
The Extralink AD-155C 48V 155W Indoor Black is a universal indoor buffer power supply designed to convert 230V AC mains to stable DC output at 48V (adjustable up to 54V) with a continuous power rating of 155W. Housed in a perforated metal enclosure with passive cooling, the unit supports connection of an external battery so connected devices continue to receive power during mains outages. The compact black casing and screw terminals simplify installation in indoor racks, cabinets or equipment rooms where reliable low-voltage DC power is required.
Passive cooling through a ventilated metal housing provides silent, maintenance-free operation while the perforations improve airflow and heat dissipation. The device offers adjustable output voltage via an onboard potentiometer to match equipment requirements. Clear screw terminal markings allow straightforward wiring for mains input, DC output and battery connection. The unit’s universal indoor design and 155W capacity make it suitable for a range of low-voltage systems that require uninterrupted DC supply.
Mount the Extralink AD-155C in a well-ventilated indoor location, leaving space around the perforated enclosure for airflow. Connect the 230V AC mains supply to the input terminals following local electrical regulations, then wire the DC output to your device(s) using the marked screw terminals. If backup is required, connect a compatible external battery to the designated battery terminals; the supply will draw from the battery automatically during a mains outage. Use the onboard potentiometer to fine-tune the DC output voltage within the supported range to match connected equipment specifications.
Ensure installation and wiring are performed by a qualified electrician. Verify the total connected load does not exceed the 155W rating and choose an external battery with appropriate capacity and voltage range for backup duration needed. Provide adequate ventilation and avoid installing the unit near heat sources or in humid environments to maintain reliable operation.
