Static Bypass Switch
Term from overvoltage technology
Classic mains overvoltage protection consists of lighting
surge arrester (class B), overvoltage protection (class C)
and, finally, the so-called appliance protection (class D)

Insulated Gate Bipolar Transistor
The latest design of high-performance transistors with
minimum control power requirement (MOSFET
structure) and minimum losses on the output side
(structure of a bipolar transistor)
See appliance protection
Light Emitting Diode
Electronic semi-conductor component, commonly
referred to as an LED, used for optic signalling.
Power Factor Correction
Circuit technology for minimising system disturbances
(particularly important when connecting non-linear
loads)
Pulse Width Modulation
Here: circuit technology for generating a sinusoidal
voltage of the highest quality from an existing DC
voltage
Simple Network Management Protocol
A protocol encountered frequently in networks for
managing / handling components
Output Voltage and Frequency Dependent from mains
supply. The UPS output is dependent on mains voltage
and frequency fluctuations. Earlier designation:
OFFLINE
Output Voltage Independent from mains supply
The UPS output is dependent on mains frequency
fluctuations, but the mains voltage is prepared by
electronic / passive voltage control units. Earlier
designation: LINE-INTERACTIVE
Output Voltage and Frequency Independent from
mains supply. The UPS output is independent of mains
voltage and frequency fluctuations. Earlier designation:
