LZSR Series

LEM enlarges the measuring range of single supplied +5 V current transducers up to 450Apk

Measuring range up to 3× primary nominal (450 A pk measured for the 150 A nominal model (LZSR 150-P/SP1))
100, 150 & 200 A nominal models
PCB mounting
ASIC based Closed Loop Hall effect technology
Low offset drift up to 3 ppm/K of V_^REF(7 times better than previous generation of C/L Hall Effect current transducers working with traditional Hall effect chip).
Unique compact size for all ranges (37.75 × 48.2 × 19.4mm)

Operating temperature range: -40°C to +85°C
Single power supply +5V
Internal reference voltage provided on an additional pin
Overcurrent detection output (threshold set at 1.93 × I_PN) available as standard option on an additional pin
Available either with an aperture for primary conductor (LZSR-P references) or integrating the primary conductor to be soldered on PCB (LZSR-TP references)
