SCHALTBAU will be showing its recently-launched flat battery power supply with static converter, for preventing deep discharge of the batteries on rolling stock which is operated under more than one electrical supply system.

Able to be fed from a range of voltages and supply frequencies, the ZH1801 and ZH1804 are suitable for all on-board power supply systems. The ZH1801 is suitable for input voltages of 1 kV or 1·5 kV AC or DC, and the ZH1804 is designed for input voltages of 1 kV or 1 kV AC and 1·5 kV or 3 kV DC. Both of the 350W units offer 24V 15A and 120V 3A DC outputs.
