Features

Control Mode:Open-loop vector control, V/F control;

Frequency setting mode: Compared output of pressure and
flow signals;

The signal transform panel adopts hall module,It can transform
0~1A signal of pressure and flow proportioning valve to be
0~10V signal to provide the feedback of inverter, also can
connect 0~10V signal;

Big torque at low frequency;

Better over-load function;

The protection class is IP54. The full-close design to prevent
dust, air and corrosion. Better adaptability of surroundings and
long using life;

Features
 For 18.5kW~75kW, the DC resistor can be built-in to
improve the power factor of output and eliminate the input
high harmonic;
 Dual-circuit mains/ saving design to ensure no fault of
system;
 Fault protection function;
 Better anti-jamming function, the input /output power line is
equipped with filter magnetism , separate wiring of high and
low electricity;
 The energy saving rate is 5%~10% higher than V/F control mode.

Disadvantage of Traditional Injection Moulding:

Valve adjustment;


Input power changes slightly;
Consume large proportion of energy;

Result in overflow.
Advantage of INVT Injection Moulding Energy-saving:

Regulate the oil pump speed automatically and the oil supply;
 Maintain the actual oil supply and the actual load flow of the
injection molding machine be consistent;

Minimize the energy consumption and eliminate overflow;

Ensure the motor to be stable and precise operation;
 Can soft start the motor, improve the power factor and save
energy.
