HO-S Open Loop Hall Effect Current Transducer by LEM

Description

The HO-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 HO-S has primary ratings of 50 – 250A and can measure up to 600A DC or AC
• A single +5Vdc power supply is required to provide power
• The HO-S Hall effect current transducer is 1% accurate* (0.5% linearity)
• It outputs 2.5V at 0A, 3.3V at the rated current (positive) and 1.7V at the rated current (negative)
• The HO-S can measure DC current and pulsed currents, as well AC frequencies up to 100 kHz (-3 dB)
• It has a fast response (2.5 to 3.5 µS) and low offset drift
• These devices have been evaluated for over voltage category III and pollution degree 2 environments
• Note that the HO-S series (when ordered from Aim Dynamics) ships with the mating connector!
• There is no need to try and special order the connector, only to get the wrong one, delay your project, etc
• *The 50A version is 1.25% accurate. See spec sheet for details
