HEYI Electric’s RECT Extended Range Current Transformer is designed and manufactured for use in places exposed to natural environments (sun, rain, wind, sand, ice and snow, temperature changes, etc.), and has a series of significant advantages and characteristics:     1.Excellent environmental tolerance: Strong weather resistance: The shell and insulation material ( cast with epoxy […]

An extended range current transformer is a specially designed current transformer whose main feature is its ability to maintain a specified measurement accuracy or protection accuracy over a wider current range than a standard current transformer, especially under overload or short-circuit current conditions well above its rated current. Detailed explanation of the key features and […]

In the Middle East, under the extremely high temperature, strong dust and high humidity environment of the coast, current sensors, as the core components for efficient operation of charging piles, solve a variety of severe challenges through precise current monitoring, system protection and energy efficiency optimization. The following is an analysis of its key role […]

Current sensors play a vital role in charging piles (especially DC fast charging piles), and their performance significantly affects the thermal efficiency and overall energy efficiency of the charging pile. Although the heat generated by the sensor itself is usually small, its measurement accuracy and reliability will indirectly but profoundly affect the thermal efficiency of […]

The current sensor itself is not the main noise source of the charging pile (such as the cooling fan or magnetic component howling), but it is crucial to achieve efficient and smooth power conversion control, and an excellent control strategy is precisely one of the key means to suppress noise (especially the howling of magnetic […]
