UPS systems/frequency converters
UPS systems are technical devices in the field of electrical engineering that ensure that important systems and installations continue to be supplied with power without interruption during power fluctuations. UPS stands for uninterruptible power supply. Electronic devices that are connected to critical systems depend on a continuous, uninterrupted power supply. In many cases, a minimal interruption to the power supply can cause data loss or shut down life-saving systems. A UPS system is a power supply system that protects electrical devices and systems from interruptions to the power supply during mains failures or power outages. In the event of a power failure, the UPS system maintains the power supply without interruption until the mains supply is restored or a generator switches the supply back on. Nowadays, a sudden power outage will affect most businesses and public authorities immensely. However, in addition to power outages, electrical equipment can be negatively affected by other electrical loads. Electrical devices are therefore susceptible to undervoltage, overvoltage, voltage drops, mains failures, voltage spikes, etc. These types of electrical loads can also have a negative impact on sensitive systems. A UPS system therefore offers the simple possibility of guaranteeing an uninterruptible power supply and thus ensures the permanent operability of the digitalized world. UPS systems are divided into three categories: UPS offline/standby, UPS line interactive and UPS online/double conversion.
