What is UPS Power Supply?

The abbreviation "UPS" stands for "uninterruptible power supply". Such a system serves as a backup power source in the event of power failures, to avoid data loss in server systems, for example.

UPS power supplies are connected between the pantograph and the mains. As soon as the energy is removed from the power grid, the UPS system takes over the servers' supply. A UPS should not act as a permanent source of energy but only serves to bridge a certain critical period.

The following two scenarios are conceivable:

• Safe shutdown: The UPS system remains active until the servers have been shut down properly and all data is backed up.
• Safe transition: The UPS system remains active until the power supply is restarted via the conventional power grid.

UPS differ in size and performance. Rechargeable batteries ensure the power supply of the systems. With rectifiers and current transformers, they reliably cushion voltage peaks and frequency fluctuations in the power grid to protect your technology from damage.

Various UPS systems offer protection against the following mains disturbances:

• Power failure (temporary or complete)
• overvoltage
• undervoltage
• Frequency variations
• harmonics in the circuit

You can prevent these sources of damage with a UPS power supply

In the day-to-day life of a company, the most diverse situations can arise, requiring a UPS intervention. Here are the most common causes of this:

• environmental factors
  As a result of particular weather conditions such as thunderstorms, voltage peaks, or individual voltage surges can occur in the power grid. With a UPS power supply, it is possible to intercept these peaks and protect your IT from damage.
• Operating conditions
  A wide variety of everyday electrical equipment, from fluorescent tubes to photocopiers, can influence the power grid's voltage. Any harmonics and individual voltage distortions can damage your IT in the long term. A UPS power supply can reliably minimize this risk factor.
• Industrial areas
  If you operate larger data centers or server complexes in an industrial environment, these can be affected by frequency fluctuations or voltage peaks caused by large and power-intensive technical devices. With an uninterruptible power supply, these discrepancies in the power grid do not disturb your IT.
• Incorrect handling
  Whether a fault occurs during technical maintenance or someone literally "pulls the plug" on your IT, our UPS systems keep your systems operational even in the event of a complete power failure until the initial state is restored.

UPS power supply systems in three classes: Different types and their level of protection

When choosing a UPS system, however, the probability of an emergency is important. What type of emergency can occur, and how sensitively your own IT reacts to these irregularities in the power grid.

To counter all possible risks, DIN EN 62040-3 distinguishes between three different types of UPS power supply systems::

• Class 1: VFI
  (Voltage and Frequency Independent from mains supply) Ideally suited for sensitive IT systems, practically no interruption until switching to the UPS system. Protects against power failures, Undervoltage and overvoltages as well as fluctuations in the power grid.
• Class 2: VI
  (Voltage Independent from mains supply) Good protection for networks and computer systems with low tolerances, interruption from 2-4 ms until switching. Protects against power failures, Undervoltage, and overvoltages.
• Class 3: VFD
  (Voltage and Frequency Dependent from mains supply) Solid protection for systems and devices without special requirements, interruption of approx. 10 ms until switching. Protects against power failures. Not recommended for sensitive IT systems.

UPS power systems properly maintained - for the continuous backup of your data

For UPS power systems to react as required in an emergency, battery maintenance is of the utmost importance. The battery life depends on the type; at about 3-4 years, the VFI UPS power supply's battery life is on average, the shortest.
