5A AC Current transformer/sensor
This content will be shared across all product pages.
The 5A AC Current Transformer/Sensor is a precision device used for measuring alternating current (AC) in electrical circuits. It typically converts high AC currents into a proportional low-current signal suitable for measurement by analog or digital devices such as microcontrollers or data loggers. This sensor is crucial for applications requiring accurate monitoring and control of electrical currents in industrial, commercial, and residential settings.
