  • Standard 96x96 mm or 144x144 mm din housing
  • LCD with backlight for voltage, frequency and/or δφ monitoring (sq 0x14 only)
  • High immunity to emc disturbances
  • Special functions set with three jumpers inside the instruments
  • Status output (option)
  • Green led for indication of both voltages
  • Lloyd’s and Bureau Veritas certificates (SQ 0204, SQ 0214, ship version)


SQ 0204 and SQ 0x14 are microprocessor controlled synchronoscopes. They are availiable with or without LC-Display or output relay and can be used for manual or semi-automatic synchronisation processes. The internal output relay is activated, as soon as the prior adjustes synchronisation conditions are fulfilled. In addition the SQ 0x14 provides a LCD, which shows bus bar voltage UBB and generator voltage UGEN, as well as both frequencies fBB and fGEN or bus bar frequency fBB and phase difference Δφ. Hence the SQ0x14 can replace two serperate voltmeters and two frequeny meters.
