EH UPS LargeEH UPS by Delta Electronics

The EH UPS is a true online, double-conversion Delta Electronics 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. True online double-conversion UPS technology isolates the output power and protects it from input anomalies. The dual input design of the Ultron EH UPS provides enhanced availability by accommodating different power supply sources.

By accepting a wide input voltage range, EH UPS units reduce probability of battery discharge to prolong battery life. Even if the UPS is under maintenance, a continuous supply of power to the load can be maintained by the use of the built-in manual bypass. 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%. PLC Technologies supplies the entire range of Delta Electronics EH UPS systems to the industry.
