HTRS Series

High accuracy compact split-core current sensors

Compact Trackside Split-core sensors

The HTRS product series is designed for measuring DC, AC, and pulse currents with nominal values ranging from 10 to 50 A, providing galvanic isolation.

These split-core sensors facilitate installation on existing power cables without the need for disconnection and reconnection, addressing the traditional inaccuracy issues of split-core sensors due to imperfect contact between the two core halves with unique LEM technology.

Featuring a compact design, HTRS current sensors are intended for DIN Rail or Panel mounting, allowing for different sensor orientations in 90° steps. They come with a 10 mm aperture and a 3-pin standard connector. 

Utilizing Hall effect technology, HTRS sensors are specifically designed for smart grid and trackside applications.

HTRS – Features and benefits

HTRS Trackside Split-core sensors

Features

  • Open loop current sensor using the Hall effect
  • Screw mounting or DIN Rail option - Both can rotate the positioning
  • Split core design for easy installation
  • 10 mm aperture
  • Insulating plastic case recognized according to UL 94-V0
  • Reverse polarity protected

Benefits

  • Easy mounting
  • Small size and space saving
  • No insertion losses
  • Non-contact measurement (doesn't need a safety case)
  • DC and AC measurement with same performance
  • Performances do not rely on the position of the cable (<0.03 % deviation)
  • Low influence from external field

Typical applications

HTRS current sensors, recognized for their capability to measure DC, AC, and pulse currents, are extensively utilized in various trackside environments. Examples of these applications include:
