Delta EH 15/20KVA
EH-15K / EH-20K

Power Reliability with the Best Total Cost of Ownership


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.True online double-conversion UPS technology isolates the output power and protects it from input anomalies. The dual input design of the Ultron EH series provides enhanced availability by accommodating different power supply sources. By accepting a wide input voltage range, EH series 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.
