The Newmar Power-Pac 14AH is a true uninterruptible DC power source for 12-volt radios and critical navigation equipment on commercial vessels, work boats and yachts. Running from 115 or 230 V AC (selected by a rear-panel slide switch, 50–60 Hz, with a standard 6-foot AC cord), it supplies highly regulated, low-ripple 13.6 V DC rated at 5 A continuous and 10 A intermittent. Regulation is 1% for line and load, and ripple is 1% peak-to-peak. The output is designed not to cause RF or audio interference in communication equipment. While AC is present, it keeps its built-in batteries charged. If AC fails, it switches to battery power automatically and recharges the batteries when AC returns. It converts AC to DC and does not produce AC power.

This model contains 14 Ah of deep-cycle sealed lead-acid batteries, made up of two 7 Ah batteries. Each battery weighs 6 pounds and measures 6 × 3.75 × 2.5 inches, and the batteries are DOT and IATA certified for air shipment. External batteries can be added in 7 Ah increments for up to 28 Ah total, and separate output terminals are provided for charging them. With fully charged 14 Ah batteries, the store listing gives approximate backup times of 100 minutes at 7 A, 60 minutes at 10 A, 30 minutes at 15 A and 15 minutes at 20 A. A 25 W transceiver at a 20% transmit duty cycle runs for about 6 hours, or about 12 hours with external batteries added.

Front-panel indicators show normal DC output and a backup-power-only warning. Audible and visual low-battery alerts trigger at 10.7 V DC, with a mute switch, and an automatic low-battery disconnect at 10.3 V DC has a manual override. Protection covers the AC input fuse, internal and external battery fuses, overvoltage, current limiting and automatic thermal shutdown. Form C AC-failure contacts are available as an option. The vinyl-laminated aluminum case measures 5.3 × 9.0 × 10.5 inches, weighs 24 pounds and operates from 0 to 40 °C. Backup runtimes depend on load current, battery age and temperature, so treat the listed figures as approximate.

Plan Backup DC Power for Critical 12 V Equipment

The Power-Pac 14AH keeps 12 V equipment running through AC outages. Check these six points before you buy.

Power-Pac 14AH or Power-Pac 7AH?

The Power-Pac 14AH and Power-Pac 7AH share the same uninterruptible 13.6 V DC supply, charger, alarms and protection. The 14AH model carries two internal 7 Ah batteries for 14 Ah total, roughly doubling backup time compared with a single battery (for example, about 6 hours versus about 3 hours for a 25 W transceiver at a 20% duty cycle). The 7AH model has internal space and terminals for a second battery.

If you do not need battery backup, a standard Newmar 115-series power supply provides regulated DC from AC with higher current ratings, such as the 115-12-20A. Choose by required backup time first, then by load current.

Frequently Asked Questions

What does the Newmar Power-Pac 14AH do?
It supplies regulated 13.6 V DC from 115/230 V AC and switches automatically to built-in batteries if AC fails, so 12 V equipment keeps running.
Is the Power-Pac an inverter?
No. It is a DC power supply with battery backup. It does not produce AC power.
How much current can it supply?
13.6 V DC at 5 A continuous and 10 A intermittent.
How long will the batteries last during an outage?
With fully charged 14 Ah batteries, the store listing gives about 100 minutes at 7 A, 60 minutes at 10 A, 30 minutes at 15 A and 15 minutes at 20 A. Actual runtime depends on load and battery condition.
Can I add more batteries?
Yes. External batteries can be added in 7 Ah increments, up to 28 Ah total, using the separate charging terminals.
What happens when the batteries run low?
Audible and visual alarms trigger at 10.7 V DC, and the unit disconnects automatically at 10.3 V DC. A manual override is provided.
Can it run on 230 V AC?
Yes. A rear-panel slide switch selects 115 or 230 V AC input, 50–60 Hz.
Can it signal an AC failure to an alarm system?
Form C AC-failure contacts are listed as an option. Contact us for details before ordering.
