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.
Time Distribution
SEL devices enable the synchronization and distribution of precise time over local-area and wide-area networks.
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.
