Product Details

This series of devices mainly consists of a variable frequency control power supply, an excitation transformer, reactors, and a capacitive voltage divider. Among them, the variable frequency control power supply uses an imported dedicated SPWM digital waveform generation chip with a frequency resolution of 16 bits, and the frequency fineness can reach 0.1Hz in the range of 20-300Hz. At the same time, it adopts an orthogonal non-synchronous fixed carrier modulation method to ensure good output waveform throughout the entire frequency range; the power part uses advanced IPM modules to ensure instrument stability and safety.

Compared with similar domestic products, this series of devices has multiple key advantages:

1. 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 adopt dry-type epoxy casting, with high mechanical strength, good electrical insulation performance, and are beautiful and reliable.

2. The variable frequency control source has a large capacity margin; strong protection functions; good output waveform; good stability; multiple working modes, easy operation; uses 220V single-phase power supply, convenient for on-site power access.
