(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
