GPS Time Server – SYNTIME

GPS Time Server – SYNTIME

GPS Time Server – SYNTIME is a sleek 1U and 19” rack mountable unit which synchronizes and maintains 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 and Galileo and IRIG. It delivers IPv4 / IPv6 supported IEEE 1588 (PTP V2), NTP V4, SNTP, SNMP, IRIG-B, PFC-Pulse, RS485, RS232 & Fiber Optic outputs. It provides nanosecond accuracy when external time references are not available. System enables configuration and monitoring through Web-based application. It offers two optional power supplies and GPS Receivers to increase the reliability of equipment. It supports 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
