CO3 and CO4 Series
High-voltage changeover unit for rail vehicles
Schaltbau C03 and CO4 Series change-over units are designed for load-free switching of electrical loads. They are applied in rail vehicles which are used in cross-border service and are operated with different high-voltage power sources.
Required control signals are generated by the corresponding Schaltbau ZH1114 Series voltage selector .
Features
- Load-free adjustment of electrical configurations to different networks, e.g. various train line voltages in accordance with UIC 550
- Suitable for all UIC voltages up to 5 kV DC max.
- Inexpensive high-voltage switch for applications requiring high
conventional thermal current - Various control programmes available in accordance with the
requirements of the European railway companies - Simple adaptation of control programme to new requirements
