In summary, LEM’s HO 6, 10, 25-P series of open-loop current transducers based on Hall-effect current sensing technology that measures AC, DC or pulsed currents with a nominal value of 6, 10, and 25 ARMS, with a response time of 3.5 µs. The HO xx-P series delivers its output as a scaled analog voltage; in most systems this will be converted to a digital value by an analog to digital converter (ADC) which requires a reference voltage. The designer can have the transducer programmed to output a reference of 0.5, 1.5, 1.65 or 2.65 V on a dedicated pin. Alternatively, the HO xx-P series can be configured to make measurements relative to an external reference. Offset and gain drift figures are improved compared to previous-generation transducers. The transducer operates from a single supply voltage at 3.3 or 5 V. It occupies a PCB-mountable, lightweight (5g) package which incorporates three separate primary conductors to allow for multi-range measurement configurations. The HO 6, 10, or 25-P series has an operating range of -40^oC to 105^oC.
