UPS allows four parallel connections

The UniStar P series single-phase on-line double-conversion UPS suits industrial, commercial, and office environments. Up to four UniStar P modules, available in 6-, 8-, and 10-kVA models, can be installed in parallel for redundancy or additional capacity.

The system protects from outages and irregularities in incoming line voltages from 160 to 280 VA at 45 to 65 Hz. It features near-unity input power factor and ac to ac efficiency greater than 90%, and less than 5% reflected harmonics. A smart-battery management system continuously monitors battery status and recharges whenever necessary. (Contact Sales for pricing and availability.)
