Power Supply With Built-in Battery Back-up
The 12V DC power supply features built-in back-up batteries which are charged during normal operation and then continues 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 ripple 10 amp output powers radios and other sensitive communications equipment without causing RF or audio interference. At the same time it float charges one or two (depending on model) built in 7 Ah back-up 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.

Operating On Battery Back Up
With 7 Ah battery installed, unit provides approximately the following power.*7 amps for 40 min.
10 amps for 20 min.
15 amps for 10 min.
20 amps for 4 min.
With 14 Ah battery installed, unit provides approximately the following power.
7 amps for 100 min.
10 amps for 60 min.
15 amps for 30 min.
20 amps for 15 min
* Assuming battery at full charge when a.c. power failed.
The Power-Pac 7 Ah (single battery model) can power a 25 watt transceiver for up to 3 hours, based on a 20% transmit/receive duty cycle. Power-Pac 14 Ah can provide the same service for up to 6 hours. Provision is made for expanding back-up power up to twelve hours (in this example – longer under lesser loads), with the installation of additional externally wired batteries (total 28 Ah max.). Batteries are automatically recharged when 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.
