HASS Open Loop Hall Effect Series by LEM

Hall effect, 50 – 600A

Clear
Product Description

The HASS series 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 HASS series has primary ratings of 50 – 600A and can measure up to ±1100A DC or AC.  A single +5Vdc power supply is required to provide power.  The HASS open loop Hall effect current transducer is 1% accurate (0.5% linearity).  It outputs 2.5V at 0A, outputs 3.125 V at the rated current (positive) and 1.875 at the rated current (negative).

The HASS open loop Hall effect series can monitor DC current and AC currents up to 240 kHz (-3 dB).  It has a fixed offset and can withstand an insulation test voltage of 3300V (1 min).  The HASS has been approved for over voltage category 3 and pollution degree 2.

Note that the HASS series (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.
