The JM21NH is an AC or DC current transducer, also known as a Hall current sensor or a Hall effect current sensor and is a split-core current transducer.
- Using Hall effect technology the JM21NH detects and transmit electrical currents
- Together with a compatible meter users can track real time power usage
- There are countless needs for real time power monitoring, some of which are listed below
- Using a split-core design this current transducer is used for the electronic measurement of AC or DC waveform currents, with galvanic isolation between the primary circuit (power) and the secondary circuit (measurement)
- 4-20mA DC output proportional to the RMS value of the primary current
