NP-24 Nav-Pac – 24VMarine communication and navigation electronics such as programmable data transceivers, GPS, and other microprocessor-controlled devices require clean and steady DC input power. Their sensitive circuitry is highly vulnerable to voltage drops from engine starts, noise and line spikes from alternators and motors, and noise from various other electronic devices. NAV-PAC prevents these conditions from affecting electronics.Features:Prevents voltage drop-out during engine start and/or other high intermittent loads such as ThrustersAbsorbs line spikesFilters out electrical interferenceProvides supplemental voltage and battery backup for up to 15 min.Optional remote panel (773-5037-0)Specifications:Output: 24 Volt @ 15 amps max.Battery: Sealed Rechargeable 5.0 Amp-Hour, 5-7 years of typical life, can be replaced. A low-voltage disconnect circuit protects the battery from total discharge. Certified by DOT and IATA for shipment by air.Noise Filtering: Audio through 200 MHZVoltage Spike Protection: Transient energy capability; 100 Joules, 4,000 amps Max (8 x 20 microseconds)Back-Up Power: 8A for 15 minutes, 12A for 8 minutes, and 18A for 2 minutesSize: 6.0 x 6.75 x 7.5 inches (13.3 X 17.14 X 19 cm)Weight: 8 lbs.
