Arc-free intelligent controller

The arc-free relay intelligent controller is an intelligent IOT terminal that has been developed and innovated by Suntrans™ for 15 years to achieve completely independent IP, and is the basic core product to support the company's digital intelligent energy control and operation and maintenance business.Arc-free relay intelligent controller is the first time after Tesla's invention of alternating current to achieve the progress of getting rid of the "arc", is to make the power equipment more reliable, more advanced, more convenient, more economical power type controller products, and by the International Institute of Electrical and Electronic Engineers (IEEE) former President Howard Mitchell affirmation and praise.At present, the products have entered the batch production stage, and more than 150,000 controllers have been applied in smart city, smart building, smart campus, smart home, smart water, smart factory and other fields, and the user feedback satisfaction is high.

Tesla in 1893 to make the popularization of alternating current, "arc" has been accompanied by the development of electricity, of which more than 90% of the technical problems of alternating current by all kinds of "arc" generated, the industry on the one hand, efforts to study how to extinguish the arc, on the other hand, the development of the whole process of automation is to rely on the "weak" control "strong".Suntrans™ original "AC over zero technology" for the first time to achieve free from "arc", its application to the development of intelligent controllers, to achieve a major breakthrough in the field of electricity, so that the power switch into the era of arc-free controller.

The breakthrough in "AC over-zero contactor load controller" technology, with 100 times the lifetime of conventional electrical controllers, makes it perfect for keeping distribution, application and automatic demand-side management or control systems ultra-reliable and stable throughout the power application case and lifetime.Breakthrough points include:①Voltage over-zero closure with no effect on the load and extended load life (millions of switching cycles life);②Current over zero breaking, no arc, zero excess, safe and reliable, low loss, no contact burning;③Millisecond operation, no harmonic interference, no electromagnetic radiation to the environment from starting or stopping;④Embedded network functions, supporting composite communications such as WIFI, TCP/IP and optical fiber, echoing the IoT cloud;⑤Strong electrical intelligence, electrical load equipment monitoring, status diagnosis, abnormal prediction and early warning;⑥Power AIoT, terminal real-time data collection, digitalization, intelligence, MRV, all in one go.

The arc-free intelligent controller becomes a kind of technically advanced "power IOT intelligent controller".

Security

Suntrans™'s Power IoT Smart Controller advances the most critical and core elements of electrical and automation control, enabling "no arc" shocks at switch closures and extending equipment life by 100 times.It is safer, more reliable, more stable, more flexible, and embedded with power relay protection for edge computing.The innovative power relay arc-free controller is embedded with all electrical monitoring functions such as current, voltage, power factor, temperature, switch counter, etc.It tracks the detailed process life of each power load it controls, the health status of the load, the power consumption of the load and all industrial logic process control between intelligent controllers, forming a true DSC system.

Simplicity

Relative to other measurement and control equipment companies or system integrators to do the framework of energy management and control systems, the need to use a large number of meters, relays, circuit breakers, sensors, cabinets and intricate wiring, and its reliability only up to the level of electronic products, ("such as large brands of electronic type PLC controller + power sensors + protection relays + various types of power contactors").Suntrans™ intelligent power IOT controller integrates the functions of "accurate measurement, precise control, relay protection, and complex communication" into one, making it a highly simple All-in-On integrated system with high reliability, full functionality, high distribution, and powerful functions such as load identification and load health status diagnosis.At present, each power IOT controller of Suntrans™ replaces such as: Siemens, ABB, Schneider, etc. or domestic such as: Huli, Zhejiang University Central Control and other well-known companies need to converge dozens of electronic devices, requiring hundreds of wires connected internally to the measurement and control system.
