LinkUPS Outdoor UPS Firetide



The Outdoor Back-Up Power System is specifically designed to provide both primary as well as uninterrupted, relaible power for critical SCADA, Surveillance, Point to Point, Point to Multi-Point and Mesh networking equipment in harsh environmental applications.

The durable NEMA 3R weatherproof enclosure has ample room for installation of radio gear including proprietary PoE interface equipment and contains environmentally hardened AC-DC power circuitry rated for long life in freezing as well as sun baked environments.

Temperature compensated charge voltage ensures that back up batteries are ready when AC power fails and provides hours of back up for loads up to 100 watts.

Supports Single and Co-Located Networking Sites

  1. These values apply at minimum input voltage conditions.
  2. The stated voltages refer to system in LINE-UP mode with a full charged battery. If the battery has been recently discharged the system will
    operate in current limited mode until the battery regains full charge. When the battery is less than fully charged, the output voltage will be lower
    than the stated values. In LINE-DOWN mode, the load voltage is roughly equal to the battery voltage. Battery voltage will be a function of state of charge, temperature and overall condition. In both modes of operation the LOAD voltage will be as much as 0.2 Volts (0.4 volts for 24 volt systems) lower than the battery voltage because of the parasitic voltage drop across the output circuit breaker.
  3. The system battery has a significant damping effect on noise; typical output noise will be much lower.
  4. The LinkUPS 120 system uses a 12 VDC battery string voltage. The LinkUPS 24/48PoE system uses a 24VDC battery string bus voltage.
