SYNTIME - GPS Time Server

The SYNTIME GPS Time Server is a sleek 1U, 19” rack mountable GPS Time Server. It is to synchronize and maintain the timing and frequency requirement of power and process industry equipment using signal obtained from different external sources such as globally available satellite systems GPS, GLONASS, Beidou and Galileo and IRIG. It can deliver IPv4 / IPv6 supported IEEE 1588 (PTP V2), NTP V4, SNTP,SNMP, IRIG-B, PFC-Pulse, RS485,RS232 & Fiber Optic outputs. It can provides nanosecond accuracy when external time references are not available. System can be configure and monitoring through Web-based application. It offers two optional power supplies and GPS Receivers. Wide range of power supply either 90V-260V AC/DC or 18-36VDC or 36V-72VDC power supply model can be mixed and matched as required by the user, depending upon power supply options available at the installation site.
