NTS 03-G+

NTS 03-G +: Multiport Network Time Server

The NTS 03-G Plus is a fully customizable satellite reference clock. It meets the demanding precision and reliability requirements of the Power, Telecommunications and Enterprise sectors.

Multiple Ethernet ports support advanced PTP and NTP time synchronization solutions, while the high drive IRIG-B option delivers legacy device interoperability. This ruggedized platform brings ultimate reliability through Rubidium and OCXO oscillator options, and time sync redundancy through Parallel Redundancy Protocol (PRP) support.

Enhanced security is delivered through fully encrypted and authenticated configuration access. Multiple user accounts are supported with configurable access control. Independently addressable and logically isolated Ethernet ports allow multiple networks to be connected to the same clock without compromising the network security. SNMPv3 and built-in NTP amplification attack immunity coupled with IRIG-B and PTP support makes the NTS 03-G Plus a versatile synchronization solution.

Villámvédelmi készlet

The antenna lightning protection kit affords additional protection through the use of an impulse suppressor installed in the antenna lead-in coax cable. In the event of a lightning-derived high voltage surge occurring on the coaxial cable, the impulse suppressor activates, short-circuiting the cable directly to the protection ground. Kit contents (all components required to install lightning protection are included): - Impulse Suppressor - Self-amalgamating tape - 2 x N-type Male crimp style connectors to match antenna cable - Crimp Tool to match the above connectors (RG59).

Antenna tartó

The antenna mounting bracket is an adjustable 500mm powder-coated steel bracket for securely mounting the timing optimized antenna option.
