The TreStar P line consists of in-line double-conversion three-phase uninterruptible power supplies (UPS) for critical loads. Up to eight modules can be installed in parallel for redundancy or additional capacity. The products feature a digital control system to eliminate all overloads, frequency variations, transients, flicker, and blackouts in real time. The digital control processes signals 10 times faster than previous analog methods. A host of standard features and available options allow the UPS to protect sensitive loads like data centers, computer systems, telecommunications systems, assembly lines, and more. Easy to install, the proven components include a user-friendly front control panel with an easy-to-read LCD panel. An output power factor of 0.9 is standard, and has a vector-controlled IGBT inverter. An input circuit breaker is provided, as well as an internal maintenance bypass. The advanced battery management system reduces the frequency of maintenance and replacement schedules, saving time and money. Staco Energy Products Co.
