You do not know, what's AOZP?      

It is one of our development - Automatic Device Lighting of  Railway Stations (АОZP).

АОЗП - is intended for inclusion and switching-off of illumination of stations platform and crossing. The illumination is included by spotlamp beams of the locomotive, which arrives on station and remains about 5 minutes or with approach of a mode day - night.

The automatic device can operate illumination:

Platforms and on duty lamp

Platforms and crossing

Crossing

       The automatic device has 2 outputs. First - lighting of a platform, other - inclusion of an on duty lamp. As an on duty lamp one of  lamps of illumination of a station platform is used. It burns during dark time of day and serves for  motorman station orientation and passengers expecting a train. If  station is connected to crossing - other output is used for illumination of crossing. In such case crossing illumination lamp carry out functions of an on duty lamp. The automatic device works under the circuit of "soft" inclusion of  lamps, that increases the term of their service in tens times. At first on lamps half of voltage moves, thus the beginning of submission is synchronized with the moment of transition through a  sinusoidal current zero of a voltage. This voltage heating a lamp about 3 seconds. After that the whole voltage moves and the lamps shine in complete force.

One more our development - Universal Automatic Lighting Device (АОУ-1).

The automatic device of station illumination is intended for automatic inclusion of illumination in a dark period of day time. It is possible to apply АОУ-1 - universal device which can provide automatic inclusion of crossing illumination , stations and other objects. The automatic device works under the circuit of "soft" inclusion of lamps, that increases the term of their service in tens time. At first on lamps half of voltage moves, thus the beginning of submission is synchronized with the moment of transition through a  sinusoidal current zero of a voltage. This voltage heating a lamp about 3 seconds. After that the whole voltage moves and the lamps shine in complete force.
