Product features for frequency inverter

1. Structural Design: Independent air duct for heat dissipation, effectively isolating pollutants from inside. Using 4-layer precision PCB board and a new generation of IGBT module technology, and mostly using IC integrated electronics. The volume and weight of new generation inverters are lighter, saving installation space.

2. Software Design: ST310 inverter control modes include: – V/F mode 0: straight line V/F 1: Multi-stage V/F 2: 1.2, 1.4, 1.6, 1.8, 2.0 powers 3: V/F separation method. Overload capacity: 150% for 60 sec, 180% for 10 sec, 200% for 0.5 sec. The drives adopt a new software speed tracking algorithm, which has a low impact on current and voltage when tracking and also has an accurate tracking speed. A maximum frequency of 3000 Hz, can be used in different machines. They have been successfully applied to chemical, metallurgy, machine tools, woodworking, textile, and many other industries.

3. Hardware Design: Full protection function. IGBT through protection, current abnormal protection, over-current, and over-voltage protection, etc. Wide voltage design of input power supply, works normally between 300-480V AC.
