en.Wedoany.com Reported - Three signal isolation amplifier products independently developed by StarRing Fusion's subsidiary, Suzhou StarRing Fusion Technology Co., Ltd. (referred to as "StarRing Electronics"), have been officially delivered to domestic universities in China for signal acquisition and isolation in fusion plasma experimental platforms such as tokamaks and field-reversed configurations. The three delivered devices, from product finalization and batch production to individual testing and factory delivery, have been executed in accordance with scientific research-grade standards, providing front-end signal assurance for university fusion research.
StarRing Electronics is the main entity for electronic and electrical products established by StarRing Fusion in Changshu, Suzhou, responsible for exporting the group's industrialization capabilities. The signal isolation amplifier belongs to its signal conditioning product line, which transforms the isolation and measurement technologies accumulated in fusion engineering into standardized equipment that can be delivered in batches and sold externally.
Fusion plasma experimental environments such as tokamaks and field-reversed configurations involve high voltage, strong electromagnetic interference, and common-mode noise, imposing extremely high requirements on the isolation capability and measurement accuracy of front-end signal acquisition systems. Adhering to the concept of "productized packaging," StarRing Electronics has condensed complex isolation requirements into standardized, modular product series, allowing research teams to use them directly and focus their research efforts on the experiments themselves.
All three products feature an isolation voltage of up to 3000 VDC, effectively cutting off common-mode interference and surge impacts on the high-voltage side, covering the complete signal chain for analog input, analog output, and digital input/output. Two of the analog isolators share a common design, supporting ±5V input, DC~100 kHz bandwidth, with 1 MΩ input impedance and built-in low-pass filters:
The WISO224-4-1U analog output isolator adopts a 1U chassis, equipped with 4 analog output isolation channels, compatible with the Advantech PCI-1720U interface.
The WISO224-32-4U analog input isolator adopts a 4U chassis, equipped with 32 analog input isolation channels, compatible with the Advantech PCI-1713U interface.
The DISO224-32-4U digital input/output isolator adopts a 4U chassis, equipped with 32 digital input/output isolation channels, supporting CMOS level signals with a transmission rate of up to 100 Mbps, compatible with the Advantech PCI-1750 interface, meeting the isolation requirements for large-scale digital I/O signals.
StarRing Electronics conducts individual and per-channel testing on all delivered products. Test items include appearance and structure, channel continuity, gain and zero offset, bandwidth compliance, isolation voltage, data rate, and other key indicators. Each item is strictly compared against product technical specifications, and products are only released after all measured data pass inspection. Each product is accompanied by a complete user manual and test report for standardized use and subsequent maintenance by users.
This collaboration with domestic universities in China represents another practice of StarRing Fusion's "productized packaging" concept in university research scenarios. Leveraging the electronic and electrical product capabilities of Suzhou StarRing, StarRing Fusion combines cutting-edge fundamental research with engineering capabilities, accelerating the transition of fusion energy from the laboratory to engineering. In the future, the company will continue to collaborate with more research institutes and universities through standardized products and services to advance the development of fusion energy.
