Advantage
Motor Starters have extended operat-
ing life in a physical space require-
ment one half the size of conventional
motor starters.
Offering motor overcurrent protection
accurate to 2% at maximum FLC,
Advantage also maintains constant
coil power regardless of varying
control circuit conditions, eliminating
coil burnout, contact chatter and weld-
ing due to low voltage of fluttering
control signals.
Advantage is designed with a full
complement of features that make
it the most versatile motor starter in
the industry. Multifunction overload
protection options provide application
flexibility while reducing inventory.
Communication capability extends
benefits, allowing Advantage to be
interactively linked to higher order
control systems for monitoring,
troubleshooting and control.
Technological advances incorporated
in the Advantage design, such as pre-
start diagnostics, increased accuracy
and the ability to communicate with
other systems, are benefits not
realized in traditional motor starters.
Features, Functions, Benefits
Advantage Breakthroughs
To achieve the level of benefits envi-
sioned for Advantage controls at a
competitive price, it was discovered
early in the development process that
simply improving existing design
concepts would fall short of the mark.
A new approach involving a higher
level of technology was required. The
result was the incorporation of three
technical breakthroughs — new
current sensing monitoring, an
energy-balanced contact closure
system that increased life by
decreasing electrical and mechanical
wear and an intelligent coil controller
optimizing the contact closing process
based on varying control circuit
conditions. Coordinating these break-
throughs to provide enhanced motor
control performance is concentrated in
the SURE chip.
Advantage uses the right combination
of brains and brawn in effecting a
motor start. The power circuit of the
contactor employs heavy-duty silver
alloy contacts scientifically designed
for long life. The addition of a uniquely
developed application-specific micro-
processor chip, regulates power
supplied to the operating coil. The
regulated closing profile is tailored to
existing control circuit conditions. This
results in an energy balanced system
which reduces armature/magnet crash
and contact bounce, extending
mechanical and electrical life.
