load Reactor dedicated for inverter testing 4A,175mH

Load reactor is designed to test frequency inverter.

Features of Three-phase load reactor:

The windings adopt foil winding structure, which has small DC resistance, Strong at short circuit withstand capability and short time overload capability;

The use of composite insulation materials with an insulation level of F or H allows the product to maintain reliable performance under severe working conditions;

Reactor has low magnetic flux density, good linearity, strong overload capability, and low noise;

The iron core adopts low-loss cold-rolled oriented silicon steel, the reactor has low loss, high efficiency and low temperature rise.
