volver a todas las categoríasUPS MINERVA 31_10/15/20 kVA
The MINERVA 31 is currently the most compact double conversion UPS system with 3-phase input and 1-phase output for use in the smallest space. It can be extended extremely fl exibly in terms of autonomy time by means of external battery packs. In addition, the input can also be confi gured as 1-phase in addition to 3-phase.
The current consumption is almost ideally sinusoidal. Furthermore, the MINERVA 31 offers an output power factor of 1.0.
With an effi ciency of up to 94.5% in normal operation, it is one of the most effective and economical UPS systems on the market and thus ideally suited for saving money.
