DIGITEK-IIIAC is
specially designed for three-phase
medium size air compressors, mainly
in the range of 30 to 100 hp or 22
KW to 75 KW, depending on the
voltages, with extensive unloaded
time. When a compressor has a very
long unloaded time, it might be
stopped running completely.
However, there are compressors
loaded and unloaded a few time per
hour with extensive unloaded time.
To avoid inrush current
contamination on the power network,
the compressors are left running
unloaded. The DIGITEK-IIIAC can
automatically stop the motor when
the maximum pressure is reached and
restart the motor with soft-start
when the pressure is below the
minimum pressure. By doing so, the
power consumption during the
unloaded period is 100% saved
without power network contamination.
In addition to the feature of
completely stop during the loaded
period, DIGITEK-IIIAC also has the
general features of the
DIGITEK-IIIGS, such as low voltage
protection, high voltage protection,
over current protection, phase loss
protection, but without remote motor
start-stop control and external
bypass.
