ZH-503 IEEE1588 time synchronization system
Detailed Product Description
ZH-503A IEEE-1588 Time synchronization system
1. DescriptionZH-503A IEEE-1588 2008 time synchronization grandmaster adopts redundant architecture in order to ensure the highest time precision of operation. It adopts CNS+GPS double navigation synchronization system, unique embedded real time hardware technology, providing high precision and wide variety of timing and synchronization information. Fully compatible with the latest IEEE-1588 precision time protocol, resolution is less than 8 nano-second. It adopts hardware time stamp, provides the highest level of time and frequency precision, which can be widely used in each different industry.
ZH-503A has various input and output interface, it can be used as grandmaster, slaves and boundary clock to satisfy different needs on site, first enterprise of using IEEE-1588 Gigabit timing interface in China. ZH-503A adopts rubidium atomic oscillator benchmark, OCXO and TCXO is optional.
ZH-503A high-precision master clock can be widely used in power system 35KV, 110KV, 220KV, 500KV and above substation (the), power plants, for the wireless Ethernet backhaul, circuit emulation services, passive optical networks, and power system 2 sub-equipment and automation devices provide time information and synchronization signals, such as: scheduling automation systems, microcomputer relay protection equipment, fault recorders, sequence of events recording devices, remote devices, computer data exchange network, lightning location system, intelligent electronic devices IED and so on.
