Automatic Tram Rail Heating Control Cabinet (ШУО) for Optimal Temperature Control

The product is designed for automatic control of heating of rails
tram switches depending on the air temperature and rail temperature.
Main functions of the product:
- individually regulate the heating power of the left and right rails of the switches depending on the supply voltage, air temperature and rail temperature (if rail temperature sensors are installed);
- monitor leakage currents in heating elements and supply cables and provide protective disconnection in case of their damage;
- measure load current and protect electronic keys from damage in case of short circuit:
- receive and process information signals from the air temperature sensor and left and right rail temperature sensors.
