Kronos Series 2 Specs

Introducing the Kronos Series 2 Satellite Clock, specifically designed for protection, automation, and control applications in power systems. Key features include high precision, multi-constellation support, output flexibility, and ethernet integration. Kronos is backed by the same NovaTech Automation sales and support policies as Orion and Bitronics products.

High Precision

The Master Clock achieves 60 nanosecond max time deviation, and includes a digital temperature-compensated backup oscillator. Antenna cable-delay compensation further enhances accuracy.

Multi-Constellation Support

Kronos is more than just a GPS clock. It can lock onto any of the GNSS constellations: GPS, GLONASS, BeiDou, or Galileo. This means more assurance of a fast lock and less time in holdover.

Output Flexibility

Unmodulated IRIG-B over twisted pair, coax, or fiber
Modulated IRIG-B over coax
PPS or PPM signals
NTP/SNTP on single or dual Ethernet

Ethernet Integration

Kronos supports browser-based configuration and SNMP is available for integration into the IT environment. NTP/SNTP can synchronize any Ethernet device not supporting twisted pair or coax. Port bonding is available on the Kronos Series 2R.
