Zhongxin Chuangwei provides a precision clock to Nanjing Enruite Industrial Co., Ltd.

Zhongxin Chuangwei provides a precision clock to Nanjing Enruite Industrial Co., Ltd.

Recently, Nanjing Enruite Industrial Co., Ltd. issued a request for a time server. Beijing Zhongxin Chuang promptly collaborated to develop a detailed proposal and recommended its self‑developed and manufactured DNTS‑92S‑OGB clock server as the bid‑winning product. Following a fiercely competitive bidding process, Zhongxin Chuang stood out thanks to its high‑quality products and comprehensive after‑sales service, ultimately securing the contract for Nanjing Enruite Industrial Co., Ltd.’s clock synchronization equipment project.

Nanjing Enruite Industrial Co., Ltd. (hereinafter referred to as the “Company”) was established by… Guorui Group Co., Ltd. and The 14th Research Institute of China Electronics Technology Group Corporation Investment‑driven establishment. Located in the Jiangning Economic and Technological Development Zone of Nanjing, it covers an area of over 60 mu and is a key enterprise of Jiangsu Province. High-tech enterprise 。

Nanjing Enruite Industrial Co., Ltd. conducted an in-depth evaluation of the DNTS-92S-OGB clock server, independently developed by Zhongxin Chuang. The test results all exceeded the specified performance requirements, and the company expressed high satisfaction with both our product quality and after-sales service, proceeding to place a successful order and put the system into operation.

The DNTS-9S network time server, developed by Beijing Zhongxinchuang Technology Co., Ltd., is an intelligent, high-precision NTP network time server. The DNTS-9S obtains standard time information from systems such as GPS, BeiDou, GLONASS, Galileo, 4G, and CDMA, and provides standard time services over the network via NTP/SNTP or other network protocols. Devices in the network that require time synchronization—such as personal computers, servers, and controllers—can synchronize with international standard time.

When used in conjunction with GNSS satellite receivers, priority can be configured, supporting single‑receiver/dual‑receiver and single‑antenna/dual‑antenna setups; each receiver can operate in either standalone or combined timing modes. If both receivers—and any other available time sources—lose signal, the DNTS‑9S relies on its built-in temperature‑compensated crystal oscillator or rubidium atomic clock to maintain timekeeping, continuously providing external time services. Leveraging all‑digital phase‑locked loop technology and a frequency‑control algorithm, it achieves superior timekeeping stability and more precise time dissemination.

In addition to serving as a primary‑level network time‑synchronization device, the DNTS‑9S can also function as a secondary‑level time server, enabling more effective time synchronization in large‑scale network environments. It provides high‑precision standard time signals for systems such as distributed networks, computer security systems, file management systems, e‑commerce platforms, online B2B systems, and cloud database storage and maintenance. The DNTS‑9S has been successfully deployed across government, finance, mobile telecommunications, public security, petroleum, power, transportation, industrial, and defense sectors.

The DNTS-9S network time server is extremely easy to install and use: simply connect the satellite receiving antenna and plug the network port into a network switch, and you can achieve time synchronization across all devices on the network.
