Eaton 9EHD range of UPSs

Eaton has launched the 9EHD range of high-efficiency ‘heavy duty’ uninterruptible power supplies (UPSs), developed to perform reliably in industrial environments.

Available in three-phase input/output ratings from 10-200 kVA and single-phase outputs up to 100 kVA, the range combines a compact footprint with the ability to operate continuously in ambient temperatures of up to 50°C. Its modular construction enables service repairs to be made in less than 90 min.

With a transformer-free design and sensing and control circuitry, 98% efficiency can be achieved while still providing maximum load protection. Advanced Battery Management technology counters the effects of high ambient temperature, extending battery life by up to 50% to lower the total cost of ownership (TCO) and enhance safety by reducing the possibility of thermal runaway.

For extremely critical applications requiring parallel redundancy, Eaton’s patented Hot Sync technology enables load sharing between parallel systems without the need for a dedicated communication line, eliminating a potential single point of failure and increasing power availability.

A large graphical LCD panel shows UPS status and allows access to measurements, controls and settings. As standard, the units have integral USB and RS232 ports as well as two Eaton Mini-Slots that can accommodate optional connectivity cards, including types for use with Ethernet and Modbus networks.
