+5V current transducers with unit offering current output

The LTSP uses the same ASIC (Application Specific Integrated Circuit) as LEM’s LTS and LTSR models. This device, designed by LEM, allows the high performance offered by the Hall-effect closed-loop current transducers to be offered in an extremely small package (22.2L x 10W x 24H mm). The LTSP provides better offset drifts than units based on traditional discrete technology, as well as access to the internal reference (2.5 V) on a separate external pin, for use with microcontrollers and/or A/D converters.

The transducer’s multi-range configuration has been designed for nominal currents of 8A, 12A and 25ARMS with galvanic isolation between the primary and output circuits. The current output allows users to manage the accuracy level and thermal drift by selecting the output resistance. The choice of the output resistor also allows the designer to adjust the gain to suit the application.

The LTSP transducer is CE marked, UL recognised and conforms to the EN 50178 standard for industrial applications. It is provided with a five-year warranty, as are all LEM industrial products.
