Products
Precise Time
SEL precise-time solutions deliver accurate, reliable time synchronization for critical infrastructure, supporting applications that require submicrosecond precision.Precise time feature comparisons
Satellite Clocks
SEL satellite-synchronized clocks provide submicrosecond-accurate time for electric utilities, data centers, public safety, and more. They meet the stringent timing requirements of applications such as land mobile radio, synchrophasors, and digital secondary systems.
Network Clocks
SEL devices serve as NTP or PTP grandmaster clocks to synchronize time-sensitive applications.
PTP Transparent Clocks
SEL managed Ethernet switches support the IEEE C37.238-2017 power system profile, enabling submicrosecond time synchronization across networks.
Time Distribution
SEL devices enable time synchronization and distribution over IRIG-B or NTP sources.
Accessories
SEL time synchronization accessories support the accurate display and distribution of satellite-based time. These devices receive signals from the Global Navigation Satellite System (GNSS) and output precise time to satellite-synchronized clocks.
