Product Features
1. The reactors of the same voltage level and capacity are smaller in size and lighter in weight; under rated load, the temperature rise is small; using dry-type epoxy casting, 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; with multiple working modes, easy operation; single-phase 220V or three-phase 380V input power supply universal, convenient for on-site power access
3. Flexible configuration. Different types of reactors can be optionally configured to meet different test object requirements, achieving multiple uses with one machine, high cost performance
