“I thought we could get by with basic metering and NTP time sync, but then we had an incident. The CyTime SER-3200 gave us the data to reconstruct why our transfer scheme switched over to generator power. Now I specify all SER devices with 1ms accuracy.“

GPS TIME SYNC—SATELLITE TIME REFERENCE (STR-100)
The STR-100 Satellite Time Reference 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™ GG 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, Eaton and Siemens.
Accurate time synchronization.
Outputs time signal with an accuracy of +/- 50 microseconds.
IRIG-B and DCF77 are widely used in electric utility, industrial, healthcare and data center applications for sequence of events recording.
IRIG-B Distribution Enhanced
The optional STR-IDM simplifies wiring of IRIG-B time synchronization signals and allows daisy-chain topology to save cable and labor costs. Used with the PLX-24V or STR-100/ IRIG-B Satellite Time Reference, the IDM enables the distribution of an IRIG-B signal over long distances and to multiple devices (up to 8 devices per IDM).

Markets & Applicatioins
“We needed to automate the EPSS testing required by the AHJ. The CyTime SER-2408 monitors status of all our ATS and makes our testing faster and more efficient.”
"I have legacy devices that use RS-485 4-wire communications, but I need to connect these to a 2-wire network. The CNV-100 from Cyber Sciences is simple—it just works!"
