Optimum voltage and bridging duration in alternating current

Digital devices and other sensitive systems require more than just a continuous supply of power. They also need a stabilized mains power supply and frequency-independent power supply in order to work properly. EFFEKTA provides appropriate systems for a vast array of different requirements. This means that its systems can do more than compensate for mains power failures with extremely short changeover times. EFFEKTA UPS units can also – depending on their design – deliver the required output level of alternating current without voltage fluctuation, voltage spikes, voltage surges, undervoltage, overvoltage or frequency fluctuations.

Different technologies are employed to supply a load with uninterruptible current. To distinguish the correct technical solution and to evaluate its protection level, the EN 50091-3 and/or the IEC 62040-3 standard is consulted. This defines UPS systems with the following abbreviations:

  • VFI: Output Voltage and Frequency Independent from mains supply)
  • VI: Output Voltage Independent from mains supply
  • VFD: Output Voltage and Frequency Dependent on mains supply)
