The SHTS-2000 series time synchronization device adopts a highly reliable industrial-grade “fully embedded” structure and fully complies with the latest national, power industry, and grid standards. It receives BeiDou and GPS satellite signals and provides a precise and reliable standard time source. The device can output various time synchronization signals, including timing pulses, IRIG-B codes, serial time messages, and network time messages, meeting the synchronization requirements of equipment in substations of different voltage levels, power plants, renewable energy stations, industrial enterprises, and other time synchronization applications.
The device features a modular design. All input and output signals of each module use electrical isolation technology, and the interface components are surge-protected and ESD-resistant, ensuring system reliability and long-term stable operation. It is widely used in power, energy, petroleum and petrochemical, steel, cement, rail transit, municipal, security, and intelligent device integration industries.
