Newmar Power-Pac 7AH Power Supply MPN - POWER-PAC7AH

$1,184.70 $1,077.00

    The Newmar Power-Pac 7AH 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 battery charged. If AC fails, it switches to battery power automatically and recharges the battery when AC returns. It converts AC to DC and does not produce AC power.

    This single-battery model contains one 7 Ah deep-cycle sealed lead-acid battery, which weighs 6 pounds and measures 6 × 3.75 × 2.5 inches. The battery is DOT and IATA certified for air shipment. Internal space and terminals are provided to convert the unit to 14 Ah. External batteries can be added in 7 Ah increments for up to 28 Ah total (14 Ah internal and 14 Ah external), and separate output terminals are provided for charging them. With a fully charged 7 Ah battery, the store listing gives approximate backup times of 40 minutes at 7 A, 20 minutes at 10 A, 10 minutes at 15 A and 4 minutes at 20 A. A 25 W transceiver at a 20% transmit duty cycle runs for up to about 3 hours, and up to about 12 hours with expansion batteries.

    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 18 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.

    Installation & Compatibility Guides

    Plan Backup DC Power for Critical 12 V Equipment

    The Power-Pac 7AH keeps 12 V equipment running through AC outages. Check these six points before you buy.

    1. Confirm You Need DC Backup

      The Power-Pac supplies 12 V DC from AC with battery backup. To make AC from batteries, you need an inverter.

    2. Match Your Load Current

      Output is 5 A continuous and 10 A intermittent. Check the draw of your radios and navigation equipment.

    3. Estimate Backup Time

      With 7 Ah, the listed times are about 40 minutes at 7 A and 20 minutes at 10 A. Runtime falls as the load rises.

    4. Plan Battery Expansion

      Add a second internal 7 Ah battery, or external batteries in 7 Ah steps, up to 28 Ah total.

    5. Set the AC Input

      Select 115 or 230 V AC with the rear slide switch before plugging in.

    6. Respond to Alarms

      Low-battery alerts begin at 10.7 V DC, and the unit disconnects at 10.3 V DC to protect the batteries.

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

    The Power-Pac 7AH and Power-Pac 14AH share the same uninterruptible 13.6 V DC supply, charger, alarms and protection. The 7AH carries one internal 7 Ah battery, with space and terminals for a second. The 14AH ships with two batteries, which roughly doubles backup time (for example, about 3 hours versus about 6 hours for a 25 W transceiver at a 20% duty cycle). Choose the 14AH if you need longer runtime out of the box.

    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.

    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 battery last during an outage?
    With a fully charged 7 Ah battery, the store listing gives about 40 minutes at 7 A, 20 minutes at 10 A, 10 minutes at 15 A and 4 minutes at 20 A. Actual runtime depends on load and battery condition.
    Can I upgrade it to 14 Ah?
    Yes. The unit has internal space and terminals for a second 7 Ah battery. External batteries can also be added in 7 Ah increments, up to 28 Ah total.
    What happens when the battery runs 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.
    How much does it weigh?
    The store listing gives 18 lb (8.2 kg) in a 5.3 × 9.0 × 10.5 in vinyl-laminated aluminum case.
