HAS 500-S/SP105 Open-Loop Hall Effect Current Transducer

HAS 500-S/SP105 Product Overview

The HAS 500-S/SP105 is an open-loop Hall effect current transducer from LEM's HAS 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 is part of a series covering 50 to 600 A, utilizing open-loop Hall effect technology with an insulating plastic case recognized according to UL 94-V0 .

Rated for 500 A nominal with a bidirectional measuring range of ±900 A, it outputs an analog voltage signal of ±4 V at rated current . Accuracy is ±1% with ±1% linearity . Response time is 3 µs and frequency bandwidth is DC to 50 kHz . Supply voltage is ±15 V (±5%) with a maximum supply current of 15 mA . Electrical offset at +25°C is < ±20 mV, and magnetic offset is < ±20 mV . The sensor offers an extended ambient operating temperature range of -40°C to +105°C . Insulation test voltage is 3.6 kV RMS with impulse withstand voltage > 6.6 kV . Mass is approximately 60 g . Mounting is panel mount with through-hole terminals and counter bored hole for transducer fastening .
