Heating control cabinet (SHUO)

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.
