Secondary Digital Clocks

2420 Series Digital Clocks
The 2420 Series feature 1.8" character, 7-segment LED's. When hardware and power supplies are a major consideration, the 2420 Series use 25% less power than the 2520 Series. See the table below for details. The catalog sheet for individual 2420 Series digital clocks can be downloaded by clicking on the image for each component in the left column.

2520 Series Digital Clocks
When you need a larger clock that's visible from over 100', the 2520 Series of digital clocks use a 2.5" character that will easily meet your requirements. The 2520 Series uses a red diffuser lens that covers the LED's that intensifies time visibility.
