Class D
See Device protection
DC/DC Booster
An electronic circuit that converts a source of direct current
(DC) from one voltage level to a higher voltage level
(DC) from one voltage level to a higher voltage level
Device protection
Term used as part of surge protection concept
The conventional mains surge protection consists of
a lightning arrester (class B), surge arrester (class C)
and finally the so-called device protection (class D)

VFD Output
Voltage and Frequency Dependent from mains
supply. The UPS output is dependant on mains voltage
and frequency fluctuations.
Formerly known as: OFFLINE
and frequency fluctuations.
Formerly known as: OFFLINE
VI Output
Voltage Independent from mains supply
The UPS output is dependant on mains frequency
fluctuations, but the mains voltage is prepared by
electronic / passive voltage regulation devices.
Formerly known as: LINE INTERACTIVE

VFI Output
Voltage and Frequency Independent from mains
supply. The UPS output is independent on mains voltage
and frequency fluctuations. Formerly known as: ONLINE
and frequency fluctuations. Formerly known as: ONLINE
