The STR-100 Satellite Time Reference (STR) is a microprocessor-based device
that accepts GPS time signals from a smart antenna or receiver and outputs a time synchronization signal
to power system devices for sequence of events recording (SER) applications. The
GPS time source may be a Trimble Acutime
TM Gold GPS “smart antenna” or an amplitude-modulated IRIG-B
signal. The STR converts this time data to a DCF77 or 1per10
protocol signal to provide time synchronization for up to 32 devices,
including
PowerLogic meters and
Sepam relays by Schneider
Electric.
Product highlights include:
Accurate time synchronization. Output time signal
within 100 microseconds accuracy.
Open solution. Modulated IRIG-B is widely used in electric utility, industrial, healthcare and data center applications for sequence of events recording.
Simple installation. Supports DIN-rail or panel mounting. GPS antenna interface
takes advantage of low-cost RS-422 cabling.
Global standards compliance. UL-listed (UL-508), cUL, CE and FCC class-A compliant.
