NTP Time Server
Flagship YZ-9811. Delivers precision NTP / SNTP / PTP timing and timestamp services to compute systems, process control, e-commerce, B2B and database clusters. Widely deployed in government, finance, healthcare, broadcasting and telecom core sites — traceable to BeiDou and the National Time Service Centre BPL long-wave.
Overview
The YZ-9811 NTP Time Server is Yinzhong's high-precision time source for IT systems — government, finance, telecom, e-commerce, B2B platforms, and database clusters — delivering NTP / SNTP / PTP / HTTPS timestamp services.
Key Specs
- Sources: BeiDou + GPS dual-system in parallel; Stratum-1 root
- Protocols: NTP v3/v4, SNTP, PTPv2 (IEEE 1588), Daytime, Time (RFC 868)
- Client capacity: ≥ 5000 concurrent NTP clients per unit
- NICs: 6 independent 10/100/1000 ports — per-VLAN isolated time service
- Holdover: < 5 μs over 24 h (< 1 μs with rubidium option)
- Management: HTTPS Web, SNMP v2c/v3, Syslog, Modbus TCP
Typical Uses
Government / e-Gov cloud
Single source of time across intranet and extranet — log timestamps are traceable to satellite, meeting MLPS 2.0 audit requirements.
Finance data centres
Meets CSRC / CBIRC timestamp and audit-log regulations. PTP output integrates with low-latency trading systems.
Data centres
Six independent NICs serve time to distinct VLANs / security domains, preventing cross-domain leakage.
Compatibility
Interoperates with Windows Server / Linux / VMware / Citrix; Cisco / Huawei / H3C / Dell EMC infrastructure validated.
Data centres, government clouds, finance machine rooms, broadcasting / telecom core sites, hospital HIS/LIS/PACS
High-Precision Network Timing
Concurrent NTP/SNTP/PTP timing and timestamps for thousands of clients
Verifiable Timestamps
Traceable to BeiDou and BPL long-wave — meets finance/government compliance
Multi-Source Redundancy
Satellite + long-wave + holdover module — stable accuracy under GNSS denial

Master-Slave Clock System
YZ-9200 master-slave clock: a YZ-9810 master clock disciplines via BeiDou/GPS and distributes to the entire site through network switches. Supplied alongside the YZ-9580 LED digital clock family (332S / 422S/D / 5S/D / 42S/D), 35cm analogue slave clocks and Wi-Fi wireless analogue / digital slave clocks — for hospitals, airports, stations, plants and office campuses.
Dispatch Auto-monitoring
YZ-8000 is a provincial-and-prefectural-integrated dispatch automation monitoring system. It safeguards the secure, stable and efficient operation of grid automation systems — providing centralised monitoring of dispatch control systems, auxiliary facilities and machine-room environments across provincial and prefectural dispatch centres.
Satellite Timing Security
Flagship YZ-9770 — in April 2022 it became the first device of its class in China to pass SGEPRI certification. Detects and isolates GNSS spoofing, jamming and suppression to deliver a "timing firewall" for grids and other critical infrastructure. Already deployed across SGCC Chongqing and other provincial grids.
Time-Sync Monitoring
A monitoring & testing family for substations, power plants, dispatch centres and data centres. Flagship models: YZ-9100 monitoring system, YZ-9900 benchtop tester, YZ-9910 handheld tester. Combined with YZ-9880 satellite common-view timing devices for traceable cross-station synchronisation.
Time Sync Devices
Our flagship product line. 1U/2U/4U master/slave clocks with multi-source time fusion (BeiDou + GPS + IRIG-B(DC) + PTP + BPL long-wave) and dual-channel hot-standby. Includes the YZ-9846 (compliant with SGCC "Four-Unification" Class-II clock spec) and self-controllable single- / dual-BeiDou variants.
