LF 1010-S Closed Loop Hall Effect Device by LEM

Closed loop Hall effect, 1000A

SKU: LF 1010-S
Product Description

The LF 1010-S by LEM is a closed loop Hall effect device designed for the measurement of DC, AC and pulsed currents up to 2700A.

oThe LF 1010-S has a primary nominal rating of 1000A and can measure up to 2700A DC or AC.  A bipolar 15 – 24Vdc power supply is required.  The LF 1010-S Hall effect current transducer is 0.2% accurate (0.15% linearity) and outputs 200 mA at the rated current.  The diameter is 38.5 mm.

The LF 1010-S can measure DC current and pulsed currents, as well AC frequencies up to 200 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 101o-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.
