T-4105 (10-20kVA)

The i-power T-4105 is a true online, double-conversion UPS. It is a proven power solution for IT rooms, telecommunications, banking, medical facilities, laboratories, and other industries in which mission critical applications cannot be disrupted. The (3P/1P) UPS is designed with a wide input voltage range to handle voltage fluctuating situations and a high accuracy output voltage to fail-safe your equipment.

The T-4105 is available in capacities from 10kVA to 20kVA. By adopting the latest IGBT technology, the T-4105 is able to offer excellent voltage switching characteristics during generator operation. An internal bypass system allowing continuous power is also integrated for convenience when maintenance is necessary. In addition, the T-4105 comes with a parallel redundant feature that allows two UPS models to operate in parallel and as backup for each other.
