Product Description

The JM21NH-V is an AC or DC current transducer also known as a Hall current sensor or a Hall effect current sensor, is a split-core current transducer. Using Hall effect technology the JM21NH-V 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). 0-5V DC output proportional to the RMS value of the primary current.
