Zhongxin Chuangwei provides clock synchronization equipment to Tongwei Solar (Jintang) Co., Ltd.

Recently, Tongwei Solar (Jintang) Co., Ltd. issued a request for a time server. Beijing Zhongxin Chuang promptly collaborated to develop a detailed proposal and recommended its independently developed DNTS‑7 time server along with digital sub‑clocks as the bid‑eligible products. Following a fiercely competitive bidding process, Zhongxin Chuang stood out thanks to its high‑quality offerings and comprehensive after‑sales service, ultimately securing the contract for the time‑synchronization server project from Tongwei Solar (Jintang) Co., Ltd.

Tongwei Solar (Jintang) Co., Ltd. was established on April 29, 2020. The legal representative is Xie Yi, and the company’s business scope includes: manufacturing solar cells and modules; solar thermal tubes, Solar water heater As well as the manufacturing of solar thermal application products; silicon wafer production; the manufacturing and installation of electrical machinery and equipment; wholesale and retail trade; import and export activities; business services; and professional technical services, among others.

Tongwei Solar (Jintang) Co., Ltd. conducted an in-depth evaluation of the DNTS-7 time server independently developed by Zhongxin Chuang. The results consistently exceeded the specified performance parameters, 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-7 network time server, developed by Beijing Zhongxinchuang Technology Co., Ltd., is an intelligent, high-precision NTP network time server. The DNTS-7 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 using GNSS satellite receivers simultaneously, priority can be configured; the system supports single‑receiver/dual‑receiver and single‑antenna/dual‑antenna configurations, with each receiver capable of operating in either standalone or combined timing modes.

The DNTS-7 features 1 to 4 adaptive 10/100/1000 Mbps Ethernet ports, with physical isolation between ports to ensure data security. All ports can be configured on the same network segment or on different segments, and the system provides redundancy: a failure in one port will not affect the normal operation of the others. Each Ethernet port must be assigned an independent IP address.
