HOYS, HOYL
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 for the HOYS Series; and of 200 A, 400 A, 600 A, and 800 ARMS nominal with galvanic isolation for the HOYL Series.
HOYS, HOYL - Hall Effect current sensors
The HOYS and HOYL product families are highly performing current sensors relying on the hall effect technology (open loop). They are to be mounted on busbars with large apertures.
The HOYS and HOYL current transducers benefit from overcurrent detection set at 2.93 x Ipn on a dedicated connection, short response time, low offset and gain drift.
These products are dedicated to the industrial domain.
