Power

The 12 VDC power source for the system shall be a battery pack charged primarily by a solar array that provides power for the system.

  • A 110 VAC charging system is also standard on all units and available for landline operation of the system. control of the power supply shall be provided by a power management system that shall regulate the charging of the batteries by the solar charging system and shall provide for temperature compensation, regulation, and distribution of power to the various functions.
  • Charging:  the system shall be equipped to provide for the charging of the 12 VDC power source batteries by either a solar charging system, or alternatively, by a 110 VAC charging system.

Solar Charging System:

  •  The solar charging system shall consist of a photovoltaic array mounted at the top of the case and a power management system.
  • The system shall provide regulated, “on demand” charging consistent with battery condition, with the ambient solar luminance at the photovoltaic array and with net power consumption within the system.
  • Charging of the batteries shall be independent of the position of any switch on the control panel. Initiation of 110 VAC charging service shall completely disconnect the solar array from the charging circuit.

110 VAC Charging System:

  • The 110 VAC charging system, supplied as standard equipment, shall consist of a temperature compensating, 110 VAC input battery trickle charger, an ammeter for monitoring the charging process and an electrical receptacle mounted on the control pedestal.
  • The system shall be configured to initiate charging of the power supply batteries when the 110 VAC service is connected without the necessity of operator intervention and shall be capable of completely charging the battery pack within a 72-hour time period in general. The actual charging time will vary depending upon conditions and state of charge/discharge of the batteries. Batteries should always be inspected for fluids, cracks, damage to terminals, etc., to ensure they are able to be charged / recharged.

Information Radio Station is a generic term synonymous with Travelers Information Station (TIS), Highway Advisory Radio (HAR) / Highway Information Systems & Low Power Radio Stations (LPR). Operation of the stations is governed by FCC Part 90.242 Rules. A FCC license is required. Information Radio Stations may be fixed or portable. Subcomponents may include transmitter, antenna and ground system, digital voice player, wattmeter, cabinet with conventional or Corbin locks, lightning arrestors for RF, power and telephone lines, coaxial cable. Most stations employ black maximized antennas to discourage ice accumulation and security measures to prevent unauthorized program access. Options include synchronization, battery backup, solar power, remote programming by local, network or telco, multi-station audio distribution via RF or LAN / WAN or wireless network.
