Ensuring the power supply for your core processes


The online UPS system is the only system that actually works uninterrupted. The battery is permanently integrated into the supply and does not have to be switched on if the mains fails. At the same time, it provides the consumer with consistent power quality through surge protection.


  • no switching times
  • line filter function


  • high acquisition costs
  • high operating costs

Offline UPS systems / Line-interactive UPS systems

With these two system variants, there can be short switchover times in the event of a power failure, which can result in sensitive electronics failing. This is particularly the case with offline UPS systems. Therefore, the line-interactive UPS system with surge protection and very short switching times is a popular alternative.


  • low to moderate acquisition costs
  • line filter function (line interactive UPS)
  • very efficient


  • Switching time at 4ms (line-interactive UPS) or up to 10ms (offline UPS)

Our UPS systems can optionally be integrated into LAN networks to improve management and monitoring. The communication protocols TCP/IP, HTTP and SNMP are supported. Allgäu Batterie supports you in making optimal use of your security systems. The networking enables efficient and centralized remote management of all UPS systems by displaying all important information. These include the input voltage, the load applied or the capacity of the batteries. In the event of a defect, the software is also able to provide detailed information about the status of the UPS. The client/server structure also simplifies the management of multi-platform network systems.


  • sequential and priority shutdown
  • cross-platform compatibility
  • scheduling of events
  • convenient user and message management
  • support for virtualized systems and all operating systems

Sensitive applications

For particularly sensitive applications, a redundant emergency power supply with at least two independent UPS systems is recommended. This gives you comprehensive protection for consumers against supply disruptions. If one of the supply sources is not within the tolerance limits, a fully automatic transfer system switches the consumers to another source. This means you receive a highly available, uninterruptible power supply.

A direct current supply system (DC UPS system) differs from a UPS system in that it supplies the connected electrical consumers with direct current. This has the advantage that the output current has fewer harmonics and is therefore cleaner.

Our DC UPS systems have output voltages of 24 V, 48 V, 60 V or 110 V. Special voltages can also be implemented on request. In terms of technology, we rely on thyristor technology or primarily clocked rectifiers, depending on the application. To ensure maximum reliability, reliable redundancies can be created by operating several rectifiers in parallel. Integration into existing control technology systems makes it easier to manage your building installation.

In the medical sector, particularly high demands are placed on power supply systems (DIN VDE 0100-710 and DIN VDE 0558-507). These are not met by industrial UPS systems, e. g. from those which are used for data backup in data centers. In order to avoid any security risk in particularly sensitive applications, the battery-supported central power supply (BSV system) is used.

Our battery-supported central power supply systems (BSV systems) for security purposes reliably supply medically used areas with electricity. They support various consumers: In the 24V DC range, these are mainly surgical lights and comparable lights. 230V AC consumers are typically therapy devices, surgical instruments, measuring and analysis devices and electrical tools. With Allgäu Batterie’s expertise, you can be confident that you can ensure their safety at all times when treating your patients, even in the event of a power failure.

Diese Batterien überzeugen mit einer besonders langen Lebensdauer im Standbybetrieb der Anlage. Lead-acid batteries are often used in UPS systems, particularly valve-regulated lead-acid batteries (VRLA). These batteries impress with a particularly long service life when the system is in standby mode.

Most manufacturers recommend replacement after 3-5 years. Actual battery life may vary depending on usage, environmental conditions and battery type. It is recommended to replace the battery as soon as it shows signs of weakness. It is advisable to carry out regular maintenance and testing procedures to check the performance of the batteries. This ensures security of supply and targeted battery replacement can be carried out before a failure.

A safety power supply is an uninterruptible power supply that meets the requirements for safety devices.

There are a number of standards and technical rules for safety power supplies, for example DIN VDE 0558-507, which refers to battery-supported central power supply systems for safety purposes.

In many cases, safety power supplies are safety systems required by building regulations. Operators are obliged to have their systems checked before commissioning, after significant changes and on a recurring basis.

The federal states have their own regulations that specify the requirements for safety power supplies. These regulations can relate to various aspects, such as: B. installation, maintenance and inspection.

In some cases, special requirements may apply to certain types of buildings or facilities, such as hospitals or places of assembly.

The duration for which a UPS system supplies power depends on several factors:

  • Battery capacity:
    The higher the battery capacity, the longer electricity can be provided.
  • Consumption of connected devices:
    The more power connected devices require, the shorter the operating time of the UPS system.
  • Age and condition of batteries:
    As the battery ages, it loses capacity, which reduces the operating time of the UPS system.

The running time of a UPS can range from a few minutes to several hours, depending on the factors mentioned above. It is also possible to extend the running time by connecting additional battery modules.
