Optional functional:
Saving time domain functions of current and voltage (all measured instantaneous values are stored) in case of power cut or other alarm events (min. 0.2s /10 period/, max. 5 sec, according to the sampling frequency and the number of input channels)

Introduction：

Wuhan Radarking Electronics Corp. is a modern share enterprises which focusing on the smart Internet of things(IOT) /smart grid energy consumption sensor/intelligent electric safety integrated solution. It established in 2002（former name: Wuhan Radarking Co.,Ltd.）and went public on January 27, 2015 with the stock abbreviation RADARKING and stock number 831722. It owns the independent R&D center and factory which is the key recommended high-tech enterprises in Wuhan city, Hubei Province.

It mainly R&D, manufacture and sell the integrated solution of smart Internet of things(IOT) energy consumption sensor/smart grid energy consumption sensor/energy consumption information acquisition and transmission(Collector, Concentrator, Communication Module), smart electric meter, smart water meter, “RDK” energy Internet of Things(IOT) intelligent energy safety integrated solution, digital campus energy consumption acquisition(meter reading) charging management integrated solution, 4-in-1 Meter energy consumption acquisition(meter reading) charging management integrated solution, 4-in-1 Meter/All-in-One Card cloud computing total charging management integrated solution, energy consumption monitoring and analysis integrated solution, mobile phone APP(Energy Consumption, Fast E Top Up).

Principle:

It pursues “Military Academy, Military Morality, Character, Integrity”business philosophy. According to the “ Success once at a time, Advance and reliable, Customer satisfaction, Continuous improvement” quality policy, produce the military high standard products depend on the talent and technology advantages.
