  • Wharton digital time and day countdown clocks are an ideal way of focusing attention on your forthcoming election, product launch or similar event.
  • Our large LED countdown wall clock displays show the exact time remaining before the event and will then provide a count-up of time after the event launch.
  • The clock uses ultra-reliable, 57mm (2.3") or 100m (4") high dot bright LED characters for time and date count. You have a choice of blue, green, red or yellow digits.

All Wharton digital clocks have many user-selected modes of operation:

  • E and NE versions can be used in stand-alone applications using their internal time references.
  • Every standard digital clock has rear connections to enable time synchronisation using one of a wide selection of time code protocols from a Wharton 5000 series master clock or suitable third party time reference.
  • You can synchronise individual clocks with a precise satellite-based atomic time reference via a control message from a Wharton 488HS series GPS or GLONASS time signal receiver.
  • N and NE versions can be controlled and synchronised to time via their 10/100Base-t Ethernet NTP connection to your existing network with accurate time information provided by a local or internet time server for simple, low-cost installation and control.


  • The high-quality clock enclosures have a silver or black finish. Alternative case colours or finishes are available at additional cost.
  • Base model clocks are suitable for freestanding or wall mounting using the multi-angled brackets supplied. Mounting options include cases for flush wall mounting and single or double-sided clocks with mounting supports for ceiling suspension.
  • 110-230V AC, 24 or 48V DC or PoE (Power over Ethernet) power supply options.
  • All Wharton digital clock products are designed, manufactured and tested to International Quality and Performance Standards.
  • Unrivalled free product lifetime technical support with unlimited advice and information to the original user for the life of the digital clock. Many previous models are still in service more than 15 years after first supply.
