SZhDM 3P


SZhDM  3P light-optical LED green strip system


Function

The SZhDM-3P speed indicator green strip is a device installed at the entrance traffic light to create a light signal in the form of a green rectangle indicating the value of the train speed when taking the side path.

It complies with the requirements of GOST R 56057-2014 "Light-optical light-emitting diode systems for railway traffic signaling. Technical requirements and methods of control".

As a light source, high-efficiency light-emitting diodes are used in the module, which allows to reduce power consumption and provide a long service life.

The case and the protective glass of the speed indicator are made of impact-resistant polymer material resistant to UV radiation.

The speed indicator is manufactured in the UKhL climatic version, category 1 according to GOST R 5228215150.
