LF 210-S Closed Loop Hall Effect Device by LEM

Closed loop Hall effect, 200A

SKU: LF 210-S
Product Description

The LF 210-S by LEM is a closed loop Hall effect device designed for the measurement of DC, AC and pulsed currents up to 420A.

oThe LF 210-S has a primary nominal rating of 200A and can measure up to 420A DC or AC.  A bipolar 12 – 15Vdc power supply is required.  The LF 210-S Hall effect current transducer is 0.25% accurate and outputs 100 mA at the rated current.  The diameter is 15.59 mm.

The LF 210-S can measure DC current and pulsed currents, as well AC frequencies up to 100 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 21o-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.
