Synchronized clock
SEL-2407®
Schweitzer Engineering Laboratories
The role of satellite clocks has grown from basic sequence-of-event and fault recorder time referencing to mission-critical roles such as synchrophasor measurement and detailed event analysis. These applications require that satellite clocks meet the same environmental standards and be as reliable as the protective relays and other high-reliability devices with which these clocks are used.
Apply in harsh substation environments. Meets IEEE C37.90 and IEC 60255 protective relay surge and environmental standards. Universal power supply operates from 18-300 Vdc and 85-264 Vac.
Apply for synchrophasor, relay event correlation,m and other high-accuracy timing needs. Provides demodulated IRIG -B time code at six outputs for driving numerous point and distributed applications.
