As an option Ni-Cd batteries can be supplied, fitted in a
separate cabinet or rack.
It is also possible to have a common battery set of Pb-Ca or
Ni-Cd type fitted in a cabinet or rack, for two equipments
in parallel.

9.3. GLOSSARY.
AC.- It is nominated as alternating current to the electrical
•
current in which the magnitude and direction varies in a cyclic
way. The most common wave shape of the alternating cur-
rent is sinewave, because the energy transmission is better.
Nevertheless, some applications could need other period wave
shapes, like triangular or square.
Bypass.- Manual or automatic, it is the physical junction be-
•
tween the input and the output electric device.
DC.- The direct current is the continuous electron flow
•
through a cable between two points with different potential.
Unlike the alternating current, in direct current the electrical
loads always flow in the same direction from the highest po-
tential point to the lowest one. Although, usually the direct
current is identified with the constant current (for example the
one supplied by the battery), it is continuous any current that
always maintain the polarity.
DSP.- It is the acronym of Digital Signal Processor.A DSP is
•
a system based on a processor or microprocessor that has
instructions in it, a hardware and an optimized software to
develop applications where numerical operations are needed
with very fast speed. Due to this, it is very useful to process
analogical signals in real time: in a system that runs in this way
(real time) samples are received, usually coming from an ana-
logical/digital converter(ADC).
Power factor.- It is defined as power factor, p.f., of an alter-
•
nating current circuit, as the ratio between the active power, P,
and the apparent power, S, or as the cosines of the angle that
make the current and voltage vectors, designating as cos φ,
being j the value of that angle.
GND.- The term ground, as its name states, refers to the po-
•
tential of the earth surface.
IGBT.- The Insulated Gate Bipolar Transistor is a semiconductor
•
device that is used as a controlled switch in power electronic
circuits. This device has the feature of the gate signal of the ef-
fect field transistors with the capacity of high current and low
voltage saturation of the bipolar transistor, combining an iso-
lated FET gate for the input and a bipolar transistor as switch
in a single device. The triggering circuit of the IGBT is as the
MOSFET one, while the driving features are like the BJT.
Interface.- In electronic, telecommunications and hardware,
•
an interface (electronic) is the port (physical circuit) through
which are sent or received signals from a system or subsys-
tems toward others.
kVA.- The voltampere is the unit of the apparent power in
•
electrical current. In direct current is almost equal to the real
power but in alternating current can defer depending on the
power factor.
LCD.- LCD acronym of Liquid Crystal Display, device invented
•
by Jack Janning, who was employee of NCR. It is an electric
system of data presentation based on 2 transparent conductor
layers and in the middle a special crystal liquid that have the
capacity to orientate the light when trespassing.
LED.- LED acronym of Light Emitting Diode, is a semiconductor
•
device (diode) that emits light almost monochrome with a very
SLC CUBE3+ PS UNINTERRUMPTIBLE POWER SOURCE
