IGBT power semiconductors of the inverter, a voltage system of the highest quality and availability on the secured busbar.
In the event of mains faults (such as e.g. current failures), the voltage continues to be supplied from the inverter to the load without any interruption. From this point onwards, the inverter draws its power from the battery instead of the rectifier. Since no switching operations are necessary, there is no interruption in the supply to the load.
The automatic electronic bypass serves to increase the reliability of the supply further, especially in the case of individual systems. It switches the public mains directly through to the load without any interruption, e.g. when there is an inverter malfunction. As a result, the automatic bypass represents an extra passive redundancy for the load.
An integrated, manually operated bypass unit ensures an uninterrupted supply to the connected loads in the case of maintenance and/or service work. The internal electronic part (with the exception of the
The greatest possible supply reliability of connected loads is attained by the parallel connection of up to max. three PROTECT 1. UPS systems. The n+x technology thus guarantees maximum reliability through up to double active redundancy on the one hand as well as on the other hand the possibility of increased power with simple redundancy or even only higher UPS power without any redundancy. The relationship between the available output power and the degree of active redundancy can be seen in the following overview:
