Product Description
FK/FK Series open current transformers
FK/FK Series
The FK/FK Series of power transformers are equipped with an open core for easy installation on site. Through the principle of electromagnetic induction, the measured source is isolated from personnel and equipment, effectively protecting personnel and property safety. The FK/FK Series provides a variety of apertures and specifications to meet different use and installation requirements. At the same time, we have a professional design team to accept customized products to meet all your needs.
Application:
Can be applied to engineering project transformation, rural power network transformation, power distribution, building energy consumption, current detection, power monitoring, and energy consumption analysis.
For power harvesting,
Metering loop electrical parameter acquisition.
