Manufacturer: ELPROMA

 

Brochures

 

The NTS-5000 is an ePRTC, PTP GrandMaster and NTP Stratum-1 server. The NTS-5000 is available with Rubidium or in the LITE version with OCXO.

The devices support a maximum of 10x LAN. The standard configuration includes 2x 100 Mbit / s (LAN1-2) - both upgradeable to 10 Gbit / s (software time stamp).

Optional EXPANDER cards (1-4) support GbE and hardware timestamps. Each network has its own private PTP / NTP / IP stacks. The cards are 100% isolated from each other to ensure the highest level of cyber security.

 

Predefined standard configurations

Each configuration contains the standard inputs and outputs 2xANT, 2xIRIG AM, 1x10MHz, 2xPPS, 2xDCLS (from left to right)

Spezifications

 

NTP / PTP1588

The device provides UTC time directly to the network (max. 10x LAN) via PTP / IEEE1588 and NTP.

LAN1 & LAN2 10 / 100Mbps
optional: LAN3-LAN10 GE Ethernet GRANDMASTER PTP / IEEE1588 with hardware time stamp Each 1-4 card has its own private IP stack. The cards are 100% isolated from each other by using analog one-way synchronization signals.
The NTS-5000 is NTP STRATUM-1 Server and PTP / IEEE1588 GRANDMASTER
It offers an accuracy of better than 200ns to UTC, supports the leap second, synchronizes continuously to UTC (jump-free) and can serve up to 100,000 NTP clients simultaneously.

 

Smart Grid Optionen

The system now also supports the PTP hardware-timestamped profiles for the optionally available 1GbE LAN3-LAN10 Ethernet interfaces

  • ITU-T G.8265.1      (telecom)
  • ITU-T G.8275.1      (telecom)
  • ITU-T G.8275.2      (telecom)
  • IEEE C37.238 v1   (Power Profile v1)
  • IEEE C37.238 v2   (Power Profile v2)
  • IEC 61850-9-3       (Power Utility via C37.238)
  • Default

Additional IRIG-B DCLS interfaces ensure high-precision IRIG-B synchronization:

  • IRIG-B DCLS RS-232
  • IRIG-B DCLS RS-422
  • IRIG-B DCLS TTL level (RS485)
  • IRIG B DCLS Fiber Optic Interface

Der Time Server NTS-5000 wurde ausführlich mit gängigen Smart Grid Relais getestet:

  • DIMAT TPU-1
  • ABB NSD570
  • SIFANG CSC-103
  • Siemens Siprotec 7SA52

 

Time reference

2 independent multi-GNSS receiver inputs (ANT1 & 2), which can also use different GNSS systems.
The second antenna with built-in receiver for redundant operation is optionally available.
The built-in RUBIDIUM oscillator (NTS-5000) guarantees stable operation even during long GNSS signal outages.

Additional input-outputs

Both ANT1 / ANT2 interfaces can be switched to output mode, emulating GNSS NMEA signals with PPSout.
The server can be synchronized with external clocks via 1PPS, IRIG-B inputs, RS232 (ToD).
It also provides a reference output time via 1PPS, IRIG-B, RS232, 10MHz, RS232 (SYSPLEX, IRIG).

Firmware

Firmware based on FreeBSD UNIX.
