HAT 1500-S Open-Loop Hall Effect Current Transducer

HAT 1500-S Product Overview

The HAT 1500-S is an open-loop Hall effect current transducer from LEM's HAT series, designed for the electronic measurement of DC, AC, and pulsed currents with galvanic isolation between the primary and secondary circuits. This base-mount sensor is part of a series covering 200 to 1500 A and is purpose-built for industrial applications requiring accurate, non-intrusive current measurement.

Rated for 1500 A nominal with a bidirectional measuring range of ±2500 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 15 mA . Output internal resistance is 100 Ω and load resistance must be greater than 10 kΩ . Insulation test voltage is 4.9 kV RMS . Operating temperature range is -40°C to +105°C . Mounting is base/chassis mount with a 30.5 mm aperture diameter . Mass is approximately 300 g and dimensions are 70 x 65 x 24 mm . Housing uses UL 94-V0 recognized materials .
