Newmar Power-Pac 7AH Power Supply with Uninterruptible Backup Battery

Power-Pac 7AH 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-Pacs highly regulated, low-rising 10-amp 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 7-amp/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 25-watt 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 28 amps/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.

The Newmar Power-Pac 7AH Power Supply is a reliable 12V DC power source designed for marine communication systems, including radios and navigation equipment. This unit features a highly regulated, low ripple output that ensures noise-free operation, making it ideal for sensitive electronic devices on commercial vessels, workboats, and yachts. Its built-in backup battery automatically activates during power outages, providing continuous power without interruption, which is critical for maintaining communication and navigation safety at sea. The Power-Pac is engineered to keep your communication systems operational even when shore power or main AC sources are unavailable, thanks to its internal 7 amp/hour sealed lead-acid batteries that are charged during normal operation.

Features:

• Highly regulated, low ripple, noise-free 12-volt output ensures clean power delivery to sensitive electronics

• Built-in standby battery provides immediate backup power in case of AC power loss, maintaining operational continuity

• Expandable design allows internal conversion from 7 A/H to 14 A/H capacity for extended backup duration

• LED indicators for output status, backup power, and low battery alerts keep operators informed of system health

• Audible low battery warning with mute switch, and automatic low voltage disconnect protect battery integrity

• Over-voltage and current limit protection prevent damage to connected equipment

• Input/output fuses ensure safety and system reliability

• Separate terminals for external battery charging facilitate system expansion

• Selectable input voltage (115/230 VAC) with user-friendly slide switch on rear panel
