Features Ø Control Mode: Open-loop vector control, V/F control; Ø Frequency setting mode: Compared output of pressure and flow signals; Ø The signal transform panel adopts hall module, It can transform 0~1 A signal of pressure and flow proportioning valve to be 0~10 V signal to provide the feedback of inverter, also can connect 0~10 V signal; Ø Big torque at low frequency; Ø Better over-load function; Ø The protection class is IP 54. The full-close design to prevent dust, air and corrosion. Better adaptability of surroundings and long using life; 4 www. invt. com. cn

Features Ø For 18. 5 k. W~75 k. W, the DC resistor can be built-in to improve the power factor of output and eliminate the input high harmonic; Ø Dual-circuit mains/ saving design to ensure no fault of system; Ø Fault protection function; Ø Better anti-jamming function, the input /output power line is equipped with filter magnetism , separate wiring of high and low electricity; Ø The energy saving rate is 5%~10% higher than V/F control mode. 5 www. invt. com. cn

Disadvantage of Traditional Injection Moulding: Ø Valve adjustment; Ø Input power changes slightly; Ø Consume large proportion of energy; Ø Result in overflow. Advantage of INVT Injection Moulding Energy-saving: Ø Regulate the oil pump speed automatically and the oil supply; Ø Maintain the actual oil supply and the actual load flow of the injection molding machine be consistent; Ø Minimize the energy consumption and eliminate overflow; Ø Ensure the motor to be stable and precise operation; Ø Can soft start the motor, improve the power factor and save energy. www. invt. com. cn 6
