HOYL-S Open Loop Hall Effect Current Transducer by LEM

Description

The HOYL-S by LEM is an open loop Hall effect device designed for the electronic measurement of DC, AC and pulsed currents with galvanic separation between the primary and secondary circuits

• The HOYL-S has primary ratings of 200 – 800A and can measure up to 2000A DC or AC
• A single +5Vdc power supply is required to provide power
• The HOYL-S Hall effect current transducer is 1% accurate
• It outputs 2.5V at 0A on the primary, outputs 3.3 V at the rated current (positive) and 1.7V at the rated current (negative)
• The HOYL-S can measure DC current and pulsed currents, as well AC frequencies up to 140 kHz (-3 dB)
• It has a fast response (~3 µS) and low offset drift
• These devices have been evaluated for over voltage category III and pollution degree 2 environments
