Wharton 5000 series Ethernet Time Server
Environment
  • Operating temperature: 0-50° C
  • Relative Humidity: 0% to 90% (non-condensing)
  • Altitude: 0 to 3,000m
  • MTBF: >100,000 hours
  • Power supply: Internal PSU 110-240V ac. 50/60Hz.
  • DUALAC dual redundant 110-240V 50/60Hz mains AC power supply option.
  • 24V dc and 48V dc options are available on request.
  • Power consumption < 100VA
  • Internal battery backup maintains the time count for > 1 year during period of mains failure.
Timing accuracy
  • 5000 series network time servers have a standard high quality integrated TCXO to provide an unsynchronised accuracy of <0.1 sec/day @ 0-45°C
  • An optional TCXOHQ may be specified to provide an unsynchronized accuracy of <0.01 sec/day @ 0-45°C
  • Locked to MSF or DCF the system accuracy is typically within 30mS of UTC when the clock is synchronised via a Wharton 482.02 MSF or 482-03 DCF77 receiver
  • Locked to GPS or GLONASS the system accuracy is typically within 5mS of UTC when the clock is synchronised via a Wharton 488.HS3-GPS or 488.HS3-GLONASS receiver.
