What does “UPS” stand for and what is a UPS system for?
UPS system means “uninterruptible power supply”, abbreviated UPS. Translated into English: Uninterrruptible Power Supply (abbreviated UPS”).
UPS systems are used to ensure the power supply of critical electrical loads in the event of disruptions in the power grid and to ensure the integrity of electronic equipment, computers, servers and other critical systems by providing an immediate source of energy when the main power supply fails or becomes unstable. The main function of a UPS system is to provide power to the connected equipment for a limited period of time, ensuring enough time to either restore the main power supply or safely shut down the systems. This is especially important to prevent data loss, system crashes, and potential hardware damage that could be caused by unexpected power outages or voltage fluctuations.
Nowadays, power protection is no longer only a means of preventing power outages, but also protects the consumer’s IT against inferior power quality, such as voltage spikes, harmonics or micro-interruptions.
For every specific situation and requirement on the part of the consumer, there are a wide variety of UPS system models with their specific characteristics.

What does a UPS system consist of? a UPS system?
Usually, a UPS system consists of the following components:
1. Battery: The battery is the heart of the UPS system. It stores energy that is delivered to the connected devices when needed. However, regular service from a specialist is important for emergencies.
2. Inverter: The inverter converts the DC voltage supplied by the battery into the required AC voltage to power the connected devices.
3. Current sensors: These sensors constantly monitor the quality of incoming mains voltage. In the event of a power failure or voltage fluctuations, the UPS system is automatically activated.
4. Automatic switching: Once a problem in the mains power supply is detected, the UPS system will automatically switch from the main power supply to the battery to provide power to the connected devices immediately. An ATS switch is suitable for this.
5. Monitoring and control: Modern UPS systems often offer the possibility of remote monitoring and control via networks. You can also send alarms to inform users of the status of the power supply.
Add-ons: UPS Bypass Switch (EBS) can be connected in addition to a UPS system to switch from UPS power to mains power and vice versa).
In addition to the components, how the UPS system works in the event of malfunctions is also decisive.

How does a UPS system work?
UPS systems protect against 9 power problems:
- Power outages
- Voltage dips
- Voltage surges
- Undervoltages
- Surges
- Transients
- High-frequency noise
- Frequency fluctuations
- Harmonics
Types and functions:
- Static UPS systems with battery system:
In the event of downtime, a UPS system can provide valuable energy. Disruptions are, for example, power outages, over- or Undervoltages in the power grid or short circuits. With innovative UPS technologies such as - On Line UPS – VFI (Voltage and Frequency Independent)
The safest of all UPS variants is the On Line UPS. The consumers are constantly supplied with artificial voltage from the battery and the mains voltage is only used to charge them. On-line UPS also monitor themselves. As soon as a fault is detected, the UPS system switches to direct mains operation and thus bypasses the UPS conversion. This process is also called bypass . - Line Interactive UPS – VI (Voltage Independent)
A Line Interactive UPS uses a mixing process between on-line and off-line technology, in which the battery is constantly charged and the power supply is usually provided by the power grid. The big difference to the off-line UPS is that the mains current is controlled by an automatic voltage regulator (AVR), which makes the output voltage much more stable. The input voltage is thus frequency-synchronous to the voltage output. This technology is used in single-phase UPS systems. Area of application: Office space. Line Interactive UPS also have a very good price-performance ratio and can also be used for smaller server systems and telecommunications systems due to the voltage filtering. - Off Line UPS System – VFD (Voltage and Frequency Dependent)
In UPS systems that are “off line”, the mains voltage is normally transmitted directly to the connected devices. However, as soon as voltage fluctuations or failures occur, the system automatically switches to battery operation. Off-line UPSs are characterized by their low price and compact design. However, they lack various filter functions and it is not possible to start the system without a network. Thus, off-line UPS are more suitable for simpler PC and peripheral devices and less for larger electrical and server systems.
What are the UPS power levels (VA, kVA, kW)?
UPS systems can be divided into different power levels:
- VA means volt ampere. VA is a legal unit of measurement for the apparent electrical power S.
- kVA means kilovolt ampere. 1 kVA = 1000VA
- kW means kilowatt. Watts are used as a unit of measurement for power (energy expenditure per period of time).

In the meantime, UPS systems also protect small and medium-sized companies from failures. In the event of a power failure, productivity must return to maximum in the shortest possible time. This also requires that the start-up times are as short as possible and that set-up and set-up times are ideally not necessary at all.
An uninterruptible power supply makes a valuable contribution to protecting production, industrial plants and control units from a wide variety of power supply problems. Voltage fluctuations and power outages continue to be a major problem for the manufacturing industry. Idle machines and systems are therefore a high risk for companies and mean losses in sales and production losses.
We recommend a redundant UPS A/B system for maximum safety. This means that in the event of a failure of the A UPS, the system automatically switches to the second UPS, the B UPS. This saves you valuable time and allows you to retrofit or upgrade the system. fix the possible error.
Reliable protection with UPS systems
For over 20 years, we have specialized in the sale of UPS systems and entire UPS systems. Our experience has shown the extent that an even small UPS system can have on entire departments or offices. UPS systems are essential in a variety of environments, including offices, data centers, medical facilities, industrial facilities, and many others where continuous power is critical. They protect not only the hardware, but also the integrity of data and ensure smooth operation. Protect yourself in good time and protect yourself from expensive power outages or power interruptions.
What capacity should my UPS have?
The required battery power for a UPS system depends primarily on the apparent power (in VA) of the consumers. By adding up the performance values of all peripherals, the minimum capacity is obtained, which ensures a bridging time of five to ten minutes in the event of a power failure. If the end devices are to be supplied with power for longer, the capacity must be increased or an emergency power generator must be switched on.
Buying Tips
When deciding on a UPS system, the environmental conditions should be considered above all.
- Is the mains voltage usually fluctuating or stable?
- Will the power grid be affected by other consumers?
- Which devices must be supplied?
- How much space can I provide for the UPS system?
Specifically, you should consider:
- the performance of all devices to be protected
- Schedule the runtime (5 to 10 minutes for a safe shutdown, longer times require the use of external batteries)
- Select type
- Check additional features
