HAX 600-S Open-Loop Hall Effect Current Transducer

HAX 600-S Product Overview

The HAX 600-S is an open-loop Hall effect current transducer from LEM's HAX series, designed for the electronic measurement of DC, AC, and pulsed currents with galvanic isolation between the primary and secondary circuits. This panel-mount sensor provides a ±4 V instantaneous voltage output and is part of a series covering 500 to 2500 A, offering a single design for a wide current ratings range.

Rated for 600 A nominal with a bidirectional measuring range of ±1800 A, it outputs an instantaneous ±4 V ratiometric voltage signal at rated current. Accuracy is ±1% with ±1% linearity. Response time is 5 µs and frequency bandwidth is DC to 25 kHz. Supply voltage is ±15 V (±5%) with a maximum supply current of 20 mA. Insulation test voltage is 5 kV RMS with an impulse withstand voltage of 8.3 kV. Operating temperature range is -25°C to +85°C. Mass is approximately 450 g. Mounting is panel mount with a module package. Housing uses UL 94-V0 recognized materials.
