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.

LIGHTNING PROTECTION KIT

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 MOUNT

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

ANTENNA CABLE

High performance CNT-240 cable, factory-fitted with a TNC-type male connector at one end, and a SMA male connector at the other. Cables are available in standard 15, 30, or 60 meter options. Contact our sales team if you require other custom lengths.

BNC-2PIN ADAPTOR

Simplifies the connection of an IED with a BNC connector to a shielded twisted pair IRIG-B wiring loom.

TIMING OPTIMIZED GPS/GLONASS ANTENNA

Dual GPS/GLONASS antenna radome that boasts exceptional out-of-band rejection, specifically designed for industrial/static timing environments. The antenna includes a pipe-mounting plinth that is designed to fit the antenna mounting bracket accessory.
