Network Time Server – NTS 03-E

Key Features:

The NTS 03-E is a secure, accurate and reliable 3 or 6-port NTP Time Server for synchronizing control and SCADA networks that provides electrical isolation and robustness in addition to new features such as remote configuration, added security, and support for Ethernet networking, and optional PTP support which make the NTS 03-E ideal for use in industrial automation, power plants and substation environments.
• Redundant power supply
• 3 or 6 NTP/SNTP ports with copper or fiber Ethernet options
• UTC and LST with user defined DST
• PTP (IEEE 1588v2) Master/Slave function
• Remote configuration over Ethernet
• Configuration encryption and security
• Enhanced Security and encryption that exceed NERC CIP requirements
