Newmar Power-Pac Power Supply

The 12V DC power supply features built-in backup batteries, which are charged during normal operation and then continue to power radios and critical navigation equipment when AC power is lost. The Power-Pac is ideal for commercial vessels, work boats, and yachts.

The Power-Pac's highly regulated, low-rising 10A output powers radios and other sensitive communications equipment without causing RF or audio interference. At the same time, it floats and charges one or two (depending on the model) built-in 7A/hour backup batteries. These are kept at peak charge during the normal functioning of the unit when AC is being supplied. In the event of a loss of AC power, the internal batteries automatically take over to power communication equipment, providing a true uninterruptible DC source.

The Power-Pac 7 A/H (single battery model) can power a 25W transceiver for up to 3 hours, based on a 20% transmit/receive duty cycle. Power-Pac 14 A/H can provide the same service for up to 6 hours. Provision is made for expanding backup power up to twelve hours (in this example, longer under lesser loads) with the installation of additional externally wired batteries (total 28A/hours max.). Batteries are automatically recharged when the AC is restored.

The operator is kept informed of all important functions, such as AC input, DC output, and battery status, with front panel indicator lights and a low battery warning buzzer.
