Power simulator MI 2891 - Metrel

Power Quality has become increasingly important as electrical installations tend to have more and more electronics present, mostly in the form of commuted power supplies, or AC / DC transformers, rectifiers, variable speed drives, LED lighting, among others.
Optimizing Power Quality increases the life of electrical equipment and prevents tripping of differential protections.
The MI 2891 Power Simulator is a multi-purpose three phase power simulator for simulating typical situations in low voltage power supply systems.
