LF 2010-S Closed Loop Hall Effect Device by LEM

Closed loop Hall effect, 3000A

Product Description

The LF 2010-S by LEM is a closed loop Hall effect device designed for the measurement of DC, AC and pulsed currents up to 3000A.

The LF 2010-S has a primary nominal rating of 2000A and can measure up to 3000A DC or AC.  A bipolar 15 – 24Vdc power supply is required.  The LF 2010-S Hall effect current transducer is 0.2% accurate (0.1% linearity) and outputs 400 mA at the rated current.  The diameter is 57.5 mm.

The LF 2010-S can measure DC current and pulsed currents, as well AC frequencies up to 150 kHz (-3 dB).  It has a fast response (<0.5 µS) and uses closed loop Hall effect technology (compensation) for maximum accuracy.  These devices have been evaluated for over voltage category III and pollution degree 2 environments.

Note that the LF 2010-S (when ordered from Aim Dynamics) ships with the mating connector!  There is no need to try and specially order the connector, only to get the wrong one, delay your project, etc.
