Project Description

High-voltage impulse track circuit device

The high voltage impulse track circuit device is used to detect the presence/absence status of the traction point in the AC 25,000 [V] train section and can be used not only in the AC train section but also in the non-train section.

Impulse Transmitter (TM)

Product Information

A device to transmit the impulse (an asymmetric waveform consisting of a positive pulse and a negative pulse) at a constant interval (± 5% per 180 pulses / minute) to a transmission impedance bond, composed of a rectifier, a control unit, and a transmission unit.

  • It is a device that detects the presence or absence of trains, and it is possible that the related track circuit device and other conditions are in any condition.
  • A device available not only for non-railroad but also for AC 25,000V 50/60 Hz, especially for double track alternating current railway sections, because this device is highly efficient and operated by a specific impulse of 3 Hz.


  • Impulse: 180 pulses / minute ± 5%
  • Input voltage: 40 ~ 60V / 400 ~ 600V
