YK-3000H NTP Server Network Time Server w/ 1U Chassis (4 Network Ports + 10-meter Portable Antenna)

YK-3000H NTP Server Network Time Server w/ 1U Chassis (4 Network Ports + 10-meter Portable Antenna)

Description:
YK-3000H NTP Server can provide high-precision and high-reliability time synchronization services for scenarios that require high-precision time services, such as power systems, automation systems, telecommunication systems, transportation systems and security monitoring. It can also receive satellite (GPS and Beidou) time signals and provide NTP time services.

Features:
* Using a multi-mode GNSS timing module, it can receive multi-system satellites. The response is fast and it can receive satellite time signals at a fast speed.
* Using AC220V power supply, it can adapt to different power supply occasions.
* Microsecond accuracy: The error between the output of the second pulse's accurate edge and the edge of the international standard time is less than 0.5us.
* A variety of time format output modules can meet different design needs.
* All signal outputs are photoelectically isolated, with strong anti-interference ability.
* Rack-mounted structure: 1U standard chassis makes it easy to install and use.
