Product Details

The NVT Model NV-ER1816i TBus Sixteen Port PoE+ Receiver Hub is a 1U 19 rack-mountable bus-architected ethernet switch, that together with remote TBus transmitters, is capable of supporting up to 64 10/100 BaseT Ethernet and PoE+ powered devices.
The TBus transmission medium can be coax, 2-wire/UTP, or Shielded Twisted-Pair. Data rates up to 150 Mbps are achievable, making these devices the ideal choice in new or legacy installations where existing cable is re-deployed as part of an upgrade to IP cameras.
An internal 250 watt 56 VDC power supply can be optionally augmented by an external 250 watt auxiliary power supply, supporting redundancy and/or higher power applications.
The NV-ER1816i is backed by NVTs award winning customer support, limited lifetime warranty, and advance replacement. No IP or MAC addressing configuration is required, yet is available for browser-based monitoring and control. This provides exceptional yet simple configuration and diagnostics for the installer or remote monitoring facility. Status LEDs indicate power, Ethernet/PoE, and TBus connectivity/activity.

Power Supply

  • The NV-ER1808i contains a 250 watt 56VDC power supply that operates off 100 to 240 VAC, 50/60 Hz. Current draw can be up to 4.5 amps. The NV-ER1808i consumes up to 30 watts, leaving 220 watts for the eight TBus ports.
  • Fuse rating
    • Use only the power cord provided with the unit or equivalent UL approved type SPT-2, SVT, or SJT 18/3 AWG 100~240 VAC, 1 Amp 60C max 15 ft 4.5 m) long. One end with IEC380-C13 appliance coupler and the other end with NEMA 1015P or equivalent for your country.
    • An optional external 250 watt power supply may be added for high load applications, or for redundancy, bringing the total power to 500 watts. The external power supply connections use an 8-conductor pluggable Phoenixstyle connector suitable for up to 16AWG (1.3 mm) conductors. Only one external 250 watt power supply may be used with each NVER1808i. For multi-hub environments, up to three power supplies are available in a shared 1U enclosure.
