It adopts the latest and most sophisticated control
technology, and use the energy regeneration of IGBT
DC supply device, so as to finish the bi-directional
control of rectifier energy feedback and realize the
real four quadrant run.
Technique features
u Renewable
control, can help to save much energy on the use of
inertial load crane application system.
u Controllable
unit power factor “1” can help to reduce the harmonic
to less than 2%.
u Applicable
to monitor operation condition and fault through the
keyboard, keep various control variables a second
before the fault, such as the voltage, current,
frequency, power and temperature, so as to
follow and refresh the data records.
Technique features
u Rectifier/feedback
unit adopt sine wave way to provide renewable
electric energy feedback to grid automatically, this
is more energy-saving and environmental than the
traditional braking unit and braking resistor.
u Excellent
closed loop vector control performance to realize
**0% torque output at zero speed.
u Four
speed control modes: no PG vector control, PG vector
control, V/F control without PG, V/F control with
PG.
Application area:
Harbor machinery, mine hoist, conveyer belt,
centrifuge, pour-into washing machine, pharmaceutical
machinery, centrifugal casting machine, and metal
processing machinery such as large punching
machine.
