Eaton 91PS and 93PS UPS
The Eaton 91PS (8-30kW) and 93PS (8-40kW) UPS are designed to protect critical servers and storage devices within computer, server room and datacentre applications. The 91PS can have a three or single phase input and provides a single phase output, (3/1 or 1/1 configured) and the 93PS is a three phase UPS (3/3 configured). The 91PS and 93PS have a high operating efficiency and compact footprint making them ideal uninterruptible power supplies for the protection of computer rooms, small datacentres, medical and industrial systems.
91PS and 93PS Features
- Lowest Total Cost of Ownership (TCO): the Eaton 91PS and 93PS UPS provide high energy efficient operating levels and with Eaton’s Energy Save System (ESS) can achieve up to 99% operating efficiency across a wide load range
- System Availability: the 91PS and 93PS UPS system is designed for high availability and to maintain a steady, clean and uninterruptible output power supply at all times
- Hot Swap and Hot Scalable: UPS modules can be easily replaced or added to the system without output supply interruption, to allow concurrent maintenance
- UPS Battery Maintenance: individual battery strings can be tested and serviced whilst the other battery strings continue to support the load
- Patented Hot Sync technology: allows load sharing without the need for communication between UPS inverters and eliminates a single point of failure in the UPS system
- Load Shedding: an advanced features that controls power to the connected loads and can equate to a 250% increase in battery runtime for a 50% load reduction when there is a mains power supply failure or power outage.
- Advanced Battery Management (ABM): built-into the 91PS and 93PS UPS architecture helps to extend the service/working life of connected lead acid battery sets by up to 50%
- Future-proof Connectivity: the Eaton 91PS and 93PS are intelligent UPS systems designed for virtualised and Cloud environments and are compatible with Eaton’s Intelligent Power Manager software package
