A term from overvoltage technology
The classical mains overvoltage protection is
comprised of a lightening current arrester (Class B),
overvoltage protection (Class C) and the so-called
device protection (Class D)
Measure for system efficiency optimisation
Efficiency Corrective Optimiser
Device for emergency switch-off
Emergency Power Off
Light Emitting Diode
Electronic semiconductor component used for
visual signaling.
Power Factor Correction
Circuitry for minimising feeding back to the mains
(especially important in the connection of non-
linear loads)
Simple Network Management Protocol
Frequently encountered protocol on the network
for managing components
Output Voltage and Frequency Dependent from
mains supply
The UPS output depends on the mains voltage
and frequency fluctuations. Previous designation:
OFFLINE
Output Voltage Independent from mains supply
The UPS output depends on mains frequency
fluctuations, but the mains voltage is processed
via electronic/passive voltage regulation units.
Previous designation: LINE-INTERACTIVE
Output Voltage and Frequency Independent from
mains supply
The UPS output is independent of the mains
voltage and frequency fluctuations. Previous
designation: ONLINE
