Designed for desktop and mountable locations in the home

The new line of FTTx DC power supply and battery backup units, Models DT30U12V-NA3 and DT30UU12V-NA3-G, are designed for desktop and mountable locations inside the home as opposed to more traditional out-of-sight locations such as garages, basements, and utility closets.  This makes these units unlike any in the industry and their flexibility allows for reduced installation costs.  These units allow providers to install the devices faster and in plain sight where they can be positioned with other utility devices such as phones, cable boxes, and home electronics.

The DT30U12V-NA3 and DT30UU12V-NA3-G models feature an advanced LED and audible indicator system for simple customer interpretation of unit status.  The improved battery maintenance and test algorithm accurately tests and maintains the battery for peak performance with minimal degradation and allows for the greatest utilization of battery capacity.

The units have an input voltage range of 100Vac – 240Vac with a frequency range of 47 – 70Hz.  The on-battery output voltage is 12Vdc nominal and runs with continuous power capacity of 30 watts and greater than 75% efficiency.  The unit utilizes a commonly available 12V 7.2AHr battery.
