T-4005 (10-40kVA)

The i-power T-4005 is a three phase-in/single phase-out, true double conversion UPS system with DSP control and isolation transformer which guarantees consistent and quality electrical power to protect your critical applications. The T-4005 is designed with a wide input voltage range to handle voltage fluctuations and high accuracy output voltage to fail safe the equipment. It has 3/1 phase structure and 1+1 parallel redundant function that allows two UPS models to operate in parallel and as backup for each other.

The T-4005 consists of an isolated transformer and an advanced SMD design, which ensures outstanding stability and high reliability. By adapting to the latest IGBT inverter technology, the T-4005 is able offer excellent voltage switching characteristics during generator operation.
