Industrial GNSS Clock

PRODUCT OVERVIEW
SGPS is a family of time synchronization system combining multi signals receiver(GPS+Beidou+IRIG), oscillators, 1 power supply and up to 3 output options in a compact 1U chassis. It comes with low cost but high performmance for being researched and designed by Silimin expert team. It is a self-contained with Temperature Compensated Oscillator (TCXO) or Quartz Crystal (OCXO) options to provide time with high accuracy UTC.     
 
SGPS family includes support for multiple output modules including Serial(RS232/RS485), IRIG-B, Pulse(PPS/PPM/PPH), NTP interfaces as well as custom outputs. Both Signal Receiver Input Modules and Output Modules are optional. Master/Slave mode is also available for installation site to serve synchronization of different intellegent devices in electric power or industrial environment.

SGPS is widely utilized in Small Substations, Power Distributions, Industrial Power Distributions, Industrial Automation sites.
