The STR-100 Satellite Time Reference Module (STRM) 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
time source may be a Trimble AcutimeTM
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
Electric and others.
Product highlights include:
Accurate time synchronization.
Output time signal
within 100 microseconds accuracy.
IRIG-B and DCF77 are widely used in electric utility, industrial, healthcare and data center applications for sequence of events recording.
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.
