The Eaton® E Series DX is a three-phase, double conversion uninterruptible power supply (UPS), and is available in 20, 30 and 40kVA output power rates. Its design fits perfectly to any environment where uninterrupted power feed is required to secure critical equipment’s continuous operation. The E Series DX UPS provides a perfect solution for power protection, and solves power quality problems such as surges, spikes, voltage fluctuations, harmonic distortion, clutter interference and frequency fluctuations. With E series DX, each phase is independently double converted and regulated. In addition, PFC (power factor control) controller is used for real time control and data processing, ensuring high availability at all times. Further extent reliability is accomplished by introducing intelligent charge mode which significantly prolongs service life of batteries. Also, possibility to have dual feed on UPS input adds availability thus increases reliability of system. As an added benefit, IP21 compliant design makes E Series DX a perfect fit to industrial and other applications, where harsh environmental conditions may set extent requirements to mechanical design. Optional filter is also available for further protection against the smallest damaging particles
