  List of Terms 

DC/DC booster 

Circuit technology for increasing a DC voltage to a 
higher voltage level

 

SBS  

 

Static Bypass Switch

 

Appliance protection 

Term from overvoltage technology 
Classic mains overvoltage protection consists of a 
lightning surge arrester (class B), overvoltage protection 
(class C) and, finally, the so-called appliance protection 
(class D) – see also http://www.phoenixcontact.de 
(“TRABTECH” topic)

 

IGBT 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) 

Class D 

See appliance protection

 

LED Light Emitting Diode 

Electronic semi-conductor component, commonly 
referred to as an LED, used for optic signalling.

 

PFC Power Factor Correction 

Circuit technology for minimising system disturbances 
(particularly important when connecting non-linear 
loads)

 

PWM Pulse Width Modulation 

Here: circuit technology for generating a sinusoidal 
voltage of the highest quality from an existing DC 
voltage

 

SNMP Simple Network Management Protocol 

A protocol encountered frequently in networks for 
managing

 /

 handling components

 

VFD Output 

Voltage and Frequency Dependent on mains 

supply. The UPS output is dependent on mains voltage 
and frequency fluctuations. Earlier designation: 
OFFLINE

 

VI 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

 

VFI

 

Output Voltage and Frequency Independent from mains 
supply. The UPS output is independent of mains voltage 
and frequency fluctuations. Earlier designation: ONLINE
