Revolutionary feature integration

The Powerware 9390 UPS is a double-conversion UPS that resolves all utility power problems and supplies clean, continuous, uninterruptible power to all connected equipment.

Hot Sync—unbreakable security

Eaton’s Hot Sync parallels two or more UPS units. Units are capable of load sharing without the need for communications wiring, hitherto the most vulnerable point of failure in all UPS systems. Each Powerware module has the ability to synchronise

Sync Control gives reliable downstream distribution

The Sync Control function maintains UPS output in sync with the external power source or another independent source.This ensures the permanent synchronisation of two independent UPS systems when the reference source

Efficiency and power factor control for optimum performance

The Powerware 9390 operates at a high efficiency of up to 94 per cent, which reduces utility costs and extends battery run times. Higher system efficiency produces cooler operating conditions, which reduces facility air conditioning cost, extends the life of UPS components, and increases overall reliability, availability, and performance.

A new input circuit design keeps input currentTHD low and input power

factor near unity without compromising overall efficiency. As a result, the Powerware 9390 allows maximum transfer of power between power source and protected load and is exceptionally compatible with multiple power sources, especially auxiliary generators. On the output side, the ultra high speed switching Pulse Width Modulation (PWM) inverter enables the Powerware 9390 to provide its full rated power capability to the load whether the load power factor is 0.9 lagging, unity, or 0.9 leading.

and support the critical load independently of the other modules.Thus all critical loads are supported by UPS-grade power, whatever maintenance needs—scheduled or unscheduled—should arise.

Hot Sync—redundant is an N+1 module system allowing full maintenance to be performed on all modules and the parallel cabinet without the need for an external maintenance bypass and without having to remove the critical load from conditioned power.

Double-conversion design offers the highest protection possible

The double-conversion design completely isolates output power from all input power anomalies and delivers 100-per cent conditioned, perfect sine- wave output—regulating both voltage and frequency. Voltage is constantly held within two per cent of nominal specification for linear loads and within
