Uninterruptible power supply
for highway maintenance depots

PERMALUX has replaced the existing safety power supply systems at various highway maintenance depots in northern Germany with new and more powerful AC and DC systems.

The newly supplied uninterruptible systems ensure the function of important telecommunications and data processing devices that are used for radio and traffic control, among other things. Due to the introduction of new technologies, such as digital transmission technology, the customer's power supply requirements have increased over time to such an extent that the existing systems were no longer sufficient.

PERMALUX therefore planned, installed and commissioned six power supply systems, each consisting of a 48V rectifier, a lead-acid battery system and a 230V/50Hz inverter.

 

With the help of an interim power supply, the replacement could be carried out without interrupting operations.
