The HOYS-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 HOYS-S has primary ratings of 100 – 560A and can measure up to 1400A DC or AC. A single +5Vdc power supply is required to provide power. The HOYS-S Hall effect current transducer is 1 – 1.25% accurate (depends on the nominal rating). It outputs 2.5V at 0A. It outputs 3.3 V at the rated current (positive) and 1.7V at the rated current (negative).
The HOYS-S can measure DC current and pulsed currents, as well AC frequencies up to 180 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.
Note that the HOYS-S (when ordered from Aim Dynamics) ships with the mating connector! There is no need to try and specially order the connector, only to get the wrong one, delay your project, etc. If you are looking for this product with a higher amperage rating see the HOYL-S models.
