GPS Satellite Clock – TTM 01-E

Key Features:

The TTM 01-E is a reliable and accurate GPS clock with sub-microsecond timing that is used to synchronize IEDs (Intelligent Electronic Devices) in the power industry and other industries where precise and reliable timing is required.

• Independently isolated outputs
• Isolated power supply
• High output power line drivers
• High noise immunity due to balanced pair distribution
• UTC and LST with user defined DST options
• Remote configuration
