Key features:
The STR-100 Satellite Time Reference is used as a GPS receiver in
conjunction with a Trimble Acutime Gold antenna, or as a
protocol converter, accepting an IRIB-B time input to synchronize
PowerLogic meters
for 1 ms resolution.
- Accepts modulated IRIG-B, or
- Trimble Acutime Gold antenna output
- DCF77 for PowerLogic meters, types CM4xxx, CM3xxx and PM8xx
- Also outputs 1per10 for Sepam relays
The STR-100 Satellite Time Reference provides GPS time sync for Square D PowerLogic meters by Schneider Electric to time-stamp
events to one (1) millisecond resolution (100 micro-second accuracy). The STR accepts a
GPS time signal from either Trimble Acutime Gold GPS antenna or
IRIG-B time source and outputs a precise DCF77 pulse for up to 32
PowerLogic meters.
