High performance, cost effective, contactless current transducers for DC, AC and pulse currents measurements
The HO DIGITAL current transducers have been meticulously optimized for the electronic measurement of DC, AC, and pulse currents while maintaining galvanic isolation between the primary and secondary circuits. The HO Digital family encompasses sensors from the HO-PW, HO-NPW, and HO-SW Series.
What sets these sensors apart from the standard HO sensors is their digital characteristic, which is achieved through a bitstream output from an onboard Sigma Delta Modulator, utilizing Pulse Density Modulation (PDM) technology.
The HO Digital sensors can be employed within a current measurement range spanning from 20 ARMS to 250 ARMS, accommodating a wide array of current measurement needs.
While the HO-PW and HO-NPW electronic parts are designed exclusively for PCB mounting and feature a 15 x 8 mm aperture for the primary conductor, the HO-SW Series is tailored for panel mounting.
Regardless of the specific series, the entire HO Digital family offers various digital output options, including 2 wire CMOS, 2 wire RS422 Manchester, 2 wires LVDS Manchester, 4 wire LVDS, or 4 wire RS422, ensuring compatibility with diverse industrial systems.
HO Digital sensors operate based on open-loop Hall effect sensor technology, which is well-suited for industrial applications where accurate and reliable current measurements are essential.
HO-SW Digital current sensors come with additional features:
The HO DIGITAL sensor family is meticulously designed for industrial applications and can be effectively utilized in a range of systems, including:
