22KW 450KW VFD 380V Frequency Inverter For Three Phase AC Motor
Description of frequency converter
Structural Design
1. Independent air duct for heat dissipation, effectively isolating
pollutants from inside.
2. Using 4-layer precision PCB board and a new generation of IGBT
module technology, and mostly using IC integrated electronics.
3. The volume and weight of new generation inverters is lighter,
saving installation space.
Software Design
1. 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
2. Overload capacity: 150% for 60 sec, 180% for 10 sec, 200% for
0.5 sec.
3. The drives adopt a new software speed tracking algorithm, which
have low impact on current and voltage when tracking, also have the
accurate tracking speed.
4. 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.
Hardware Design
1. Full protection function. IGBT through protection, current
abnormal protection, over-current and over-voltage protection etc.
2. Wide voltage design of input power supply, works normally
between 300-480V AC.
Humanized Design
1. Multiple sets of motor parameters can be customized.
2. Provide parameters for four failure records.
3. The whole series is equipped with a 1/1 scale paper shell
template for mounting holes, so as to realize more convenient and
fast electrical cabinet installation.
4. The fan partition is pull-out and detachable, and the fan can be
taken out directly, which is convenient for daily maintenance.
