Surge technology term
The conventional mains surge protection consists
of an mains earthwire (class B), an overvoltage
protection (class C) and an appliance protection
(class D) – see also e.g. under
http://www.phoenixcontact.de (topic „TRABTECH")
see appliance protection
Circuit technology to boost the direct current on a
higher voltage level
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)
Light Emitting Diode
Electronic semiconductor component, commonly
called light diode. Used for optical signalling.
Power Factor Correction
Circuit technology to minimize circuit backfeed
(important for 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
common protocol in networks to manage / control
appliances
Output Voltage and Frequency Dependent from
mains supply
The UPS output depends of mains voltage and
frequency variations. Former notation: OFFLINE
Output Voltage Independent from mains supply
The UPS output is independent of mains voltage
and frequency variations. The mains voltage
however is rectified by electronic / passive voltage
regulators. Former notation: LINE-INTERACTIVE
Output Voltage and Frequency Independent from
mains supply
The UPS output is independent of mains voltage
and frequency variations. Former notation: ONLINE
