This is our latest 2500KVA frequency converter, which has two major technical highlights:

1. The input transformer adopts pre-magnetization technology to eliminate inrush current generated during transformer closing, achieving zero-impact current closing of the frequency converter;

2. It utilizes wave-by-wave current limiting technology. Let me show you inside the equipment.

This is our wave-by-wave current limiting technology verification test. This is our 90kW motor with delta direct start. Its maximum starting current is over 2000 amps. While our 2.5MW frequency converter can easily start this motor, for 300kW, 500kW, or larger motors, our wave-by-wave current limiting technology is necessary.

Now, using this technology, we can arbitrarily control the motor's starting current. What was originally an output of 2000A now only requires 1600A.
