UPS - backup power supply
EH Series, 10kVA to 20kVA (3:1)
The Delta Ultron EH series is a true online, double-conversion UPS. It is a proven power solution for IT rooms, telecommunications, banking, medical facilities, laboratories, and other settings in which mission critical applications cannot be disrupted. For a modest initial investment, the double-conversion UPS series – EH provides both outstanding quality and one of the lowest costs of ownership for UPS systems within the 10-20 kVA range. To shrink the cost of operation even more, the units can be run in ECO mode for efficiency of up to 96%.
