HOYS Series

High performance, contactless current sensors for DC, AC and pulse currents measurements of 100 A, 200 A, 400 A, 500 A, and 560 ARMS nominal with galvanic isolation

HOYS Series – Hall Effect Current Sensors

The HOYS Series comprises high?performance open?loop Hall?effect current sensors designed for accurate measurement of DC, AC, and pulsed currents up to 560 Arms in industrial environments.

Intended for busbar mounting, HOYS sensors feature large apertures, allowing easy integration into high?current systems while maintaining reliable electrical isolation.

HOYS current transducers offer fast response time, low offset and gain drift, and include an overcurrent detection function set at 2.93 × Ipn, available via a dedicated output connection.

These characteristics make the HOYS Series well suited for industrial applications requiring stable current measurement and integrated protection signaling in compact mechanical formats.
