Product Features

1. The reactors of the same voltage level and capacity are smaller in size and lighter in weight; the temperature rise is small under rated load; they are dry-type epoxy cast, with high mechanical strength, good electrical insulation performance, beautiful and reliable 

2. The variable frequency power supply control box has large capacity margin; strong protection functions; good output waveform; good stability; multiple working modes, easy operation; compatible with single-phase 220V or three-phase 380V input power, convenient for on-site power supply

3. Flexible configuration. Different types of reactors can be selected to meet different test requirements, achieving multiple uses with one machine, high cost performance
