UPS technology
Uninterruptible power supply
Mains voltage variations occur more often than expected.
The consequences of this are crashes, loss of data and cost
intensive downtimes. The solution is an uninterruptible
power supply (UPS) which offers various level of protection.
There are three different UPS topologies offering different
protection levels against all 10 types of mains disruption and
variation.
Optimal protection for every application
Outage-blackouts ( > 10ms)
Sags/brownouts
Dynamic overvoltage
Undervoltage (continuous)
Overvoltage (continuous)
Transients/Surges
Frequency variations
Voltage distortions (bursts)
Voltage harmonics
Lightning
VFD VI
VFI
The VFD technology protects against the mains variations caused
by network disruptions, brownouts and voltage peaks.
The VI technology protects against the most common mains
variations. It‘s a good compromise between protection and costs.
The highly reliable VFI technology offers the best protection
against mains disruptions and variantions. This technology
provides a clean and secure supply of power for all critical
applications and sensitive hardware.
