Mobile communication electronics such as programmable two-way radio and data transceivers, vehicle location systems 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 all of these problems and is in use by thousands of Emergency Vehicles nation wide.

  • Prevents voltage “drop-out” during engine start
  • Absorbs line “spikes”
  • Filters out electrical interference
  • Provides supplemental voltage/battery back-up for up to 15 min.
  • Remote monitor panel provided
