SZhDM 2P, ZhSM 2

SZhDM 2P, ZhSM 2 led railroad modules


The LED module of the dwarf traffic light is used in railway traffic lights of electrical centralization (SZhDM 2P), in railway traffic lights of electric centralization (SZhDM 1) and on access roads of industrial enterprises (ZhSM 2)

Modules comply 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 modules are made of impact-resistant polymer material resistant to UV radiation.

The modules are manufactured in the UKhL climatic version, category 1 according to GOST R 5228215150.
