Overview
ES-942 Stand Alone LED Clock
The ES-942 (12hour)/ES-944(24 hour) is a stand-alone clock for applications not requiring GPS or temperature controlled stability. The ES-942/944 uses the AC line-frequency as a time reference or, optionally, a quartz crystal timebase may be specified. Fast, Slow and Hold controls are accessible on the top of the case.
| C | Crystal Time Base: A crystal reference is employed for those applications requiring independence from the line frequency. A trimming function is included for greater accuracy (2-3 seconds/week). |
| ESE | ESE Time Code Output: An ESE Time Code output is provided allowing the unit to drive ESE Time Code Slaves. |
| J | 220 VAC/50 Hz Operation: The unit is configured to operate from 220 VAC line voltage. 117 VAC 50/60 Hz is standard. |
| UL | "UL" Approved Power Supply: The unit is supplied with a UL/CSA approved wall mount power supply. |
| W | 3-Wire Power Cord: Recommended where static charges can occur. Standard on many units, otherwise a 2-wire cord is supplied. |
