ESE ES-172U Console Mount Digital Clock

The ES-172U is a low-cost console-mount clock for applications that do not call for GPS or oven-controlled stability, showing time on a .4 inch red LED display sized to sit flush in a desk or console. It references AC line frequency as standard, with an optional quartz crystal timebase for facilities where the power line is not a reliable clock.

A rear connector carries Fast, Slow and Hold control inputs for setting the time, with front-panel control switches available as an option when a local operator needs to set it directly. It runs on 110-120 VAC standard, with 220-240 VAC and UL options available, and a 24-hour version, the ES-174U, is offered for military-time facilities.
