Import Ct-Tss3000 Grandmaster Clock — Buy in Bulk from Supplier in China

The CT-TSS3000 Grandmaster Clock is a precision time synchronization device designed for critical infrastructure, operating as a Stratum 1 time server using GPS L1 and BeiDou B1 satellite signals. It supports multiple input protocols including PTP, IRIG-B, BITS, and 10 MHz references, and delivers outputs in NTP, PTP, IRIG-B, 1PPS, serial TOD, and 10 MHz formats over RJ45, BNC, and fiber interfaces. The unit features a 19-inch 4U rack mount design with redundant dual power supplies and an LCD interface for local configuration and status monitoring.

Internally, the device uses an OCXO oscillator for holdover stability, with a frequency accuracy of 1e-12 per day after 24 hours of satellite lock and a holdover drift of 1 microsecond per hour. Time accuracy to UTC is specified at 100 nanoseconds RMS. The system includes a time delay compensation mechanism ranging from 20 nanoseconds to 500 milliseconds and a continuity judgment algorithm to prevent output discontinuities. It is built to operate in high electromagnetic interference environments and supports IEC 61850 and IEC 60870-5-104 protocols for utility and industrial automation systems.

This clock is typically deployed in power substations, telecommunications hubs, financial trading systems, and military command centers where sub-microsecond timing is required. Buyers include system integrators, utility operators, and network infrastructure providers sourcing for hardened, redundant timing solutions. The device supports hot, cold, and duplex standby configurations, and output modules are field-configurable. Packaging is standard industrial rack mount with no custom enclosures offered. Lead time and MOQ must be confirmed directly with the supplier.

Chengdu Cove Technology Co., Ltd. is a technology supplier based in Chengdu, Sichuan, specializing in industrial time synchronization systems. The company's profile indicates a harbor trust tier, suggesting verified business registration and physical address validation, but no public information confirms years of operation, employee count, or client list. The listing shows no response rate or average response time, indicating limited or inactive communication channels on the sourcing platform.

The supplier focuses on hardware products for time-critical applications, with the CT-TSS3000 as its primary listed device. There is no mention of certifications such as ISO, CE, or RoHS, nor are test reports, quality control procedures, or R&D capacity described. The company does not appear to offer custom firmware, software integration services, or global after-sales support beyond the product hardware itself. Buyers should treat this as a hardware-only sourcing opportunity requiring direct technical validation.
