Mobile DC UPS, Voltage Protection

Nav-Pac & StartGuard DC Power Conditioners provide a clean and reliable source of DC power for proper operation.

Electronics are highly vulnerable to shut down / reboot / data corruption caused by power drop out during engine start and low voltage from over worked batteries. RF  Interference generated by alternators and motors also impedes proper operation. A DC UPS is the remedy to these issues:

Nav-Pac –Continuous Voltage Protection

Mobile communication electronics such a programmable two-way radio and data transceivers, vehicle location system and other microprocessor controlled devices require clean and steady DC input power. Their sensitive circuitry is highly vulnerable to voltage drop from engine start, noise and line spikes from alternators and motors, and conducted noise from various other electronic devices. NAV-PAC prevents these conditions from affecting electronics.

Features of the Nav-Pac

  • Prevents voltage “drop-out” during engine start and/or other high intermittent loads such as Thrusters
  • Absorbs line “spikes”
  • Filters out electrical interference
  • Provides supplemental voltage/battery back-up for up to 15 min.
  • Remote monitor panel provided, NP-12 only

StartGuard  – Voltage protection during engine start

The abrupt DC system voltage drop that accompanies engine starting can cause communication/navigation electronics to “dump” programmed memory. SartGuard solves this problem by providing supplemental voltage to sensitive electronics while the engine is cranked.

Features of the StartGuard

  • Contains a seales rechargeable battery which is switched on-line to electronics when sensing the starter switch or solenoid is engaged.
  • When the engine is running StartGuard automatically goes off-line and the internal battery is recharged by the alternator.
