Product Description

                                           High Voltage Variable Frequency Inverter for Various Machines
1. Application
This product is used in the soft start, soft stop and operation process control and energy-saving application of electric motors in coal mines and other mining, petroleum and chemical applications. It is especially suitable for lifting winches, belt conveyors and scraping in coal mines or ground mines to realize variable frequency speed control of board conveyors, fans, pumps, pressure fans and other equipment.


2.  Product advantages
The starting current is small, the impact on the power grid is small, and the harmonics are small.
Start smoothly, speed regulation smoothly, output waveform approximate to positive bass wave.
Simple control operationUsing modular structure, easy maintenance
Rich communication interface
Process control adjustment and optimization
Obvious energy saving effect, economic operation
The 10-inch display shows that the "commissioning navigation system" and "maintenance navigation system" are built in, so that users can debug and repair the work by themselves, and set the component "life alarm system" to issue an alarm when the component is near the end of its service life. When the component life is damaged, it affects production.
