Frequency Clocks

At Hertz Electronics, our frequency clock systems are designed to provide an integrated and accurate display of time and frequency information for power generation facilities. Frequency clock displays are available with red, green, yellow or blue LED characters with a legibility of 601.057 = 25m, 601.100 = 50m, 610.02 = 10m.

 

Our frequency clocks’ Standard Time is based on an extremely accurate internal quartz crystal or, in some cases, can be synchronised to an external time reference, like a GPS receiver. The internal quartz crystal in our frequency clocks is temperature compensated with an accuracy of 0.1 second per day.

 

The clocks’ Frequency Time is based on the 50 or 60 Hz supply frequency with an accuracy of +/-0.001% +/-1 digit from 20-80Hz. Frequency clocks feature a serial RS232 + RS485 data port is provided which allows multiple displays to be synchronised or the time/frequency data from a computer to be displayed.

 

Frequency clock displays are fitted with a universal 100-250V 50/60Hz power supply. Optional 24 or 48VDC supplies are also available at extra cost.
