The SureStart Difference
The term “softstart” is used generically when referring
to devices such as SureStart. It is worthwhile to
note that SureStart is not a “hard start” device. As
the name implies, it is a SureStart
TM
which ensures
the compressors starts optimally every time by not
delivering too much nor too little torque.
SureStart applies power electronics combined with
intelligent software to provide optimal mechanical
advantage during motor starting. SureStart technology
maintains optimal torque while maximizing starting
effi ciency over a range of power supply conditions.
By comparison, other softstarters normally have only a
Voltage ramp up where run and start windings are not
controlled separately.
• SureStart does not compromise the torque or the
time needed to achieve rotational speed.
• It compensates for poor power conditions such as
high cable impedance, low Voltage or both.
• It has a sophisticated learning algorithm to optimize
the starting time performance based upon various
factors some of them being: the line impedance
(refl ected from the input voltage to motor) and
the time it takes for the motor to reach up to
full speed. This ensures auto regulation of start
performance for different sized motors without any
human intervention.
• The SureStart also reduces the voltage dip in the
power line during starting.
• Light fl ickering reduced by up to 10 times during
start up when units have a SureStart in the circuit.
• Built-in fi rmware inside SureStart helps eliminate arc
damage to the motor contactor due to chattering.
• SureStart is out of the circuit after startup. It
consumes less than 2W average in running mode.
• The SureStart protects against motor reversal by
preventing restarts in event of intermittent lapse
in power supply. Motor reversal is possible during
turn off cycles when the back pressure forces the
compressor to rotate in reverse direction.
• SureStart will protect the motor by not allowing it to
start under adverse low voltage conditions.
• Loss of power detection includes sensing of low
voltage sags and intermittent power drop outs
(lasting 0.1-3 seconds).
