    Description

    The Rack Series, Rackmount, 16-Port, 18 Volts Clamping


    Quick Facts

    • Hot-swappable modular ports. Swap out lines without affecting other ports.
      　

    　

    Further Details

    • Easy front input/output access.
    • Self-resetting modular nodes.
    • Use the 7.5-volt model for 10BASE-T, RS-422/RS-423, RS-485 and CATV applications.
      　
    • Use the 18-volt model for Token Ring, RS-232, Digital 4–20 mA Current Loop, and satellite TV applications.
      　
    • Use the 240-volt models for dialup voice lines, modem, and fax lines.

      These protectors are specifically designed to give added security to your data/voice and network equipment with extremely low tolerances for static electricity, voltage rises, or ground loops.

      Protect one concentrator or an entire relay rack full of hubs, concentrators—even your ATM and leased lines.

      The Rack Series Surge Protectors, Rackmount, are truly modular. Connect and disconnect individual ports without disrupting other ports. Continuous uptime is guaranteed. And after a power anomaly of up to 1500 watts, the ports reset automatically.
