T-4008 (160-500kVA)

i-power T-4008 is a high end double conversion three phase-in/ three phase-out transformer based UPS. With the advanced IGBT technology for power factor correction and inverter, the

T-4008 features exceptional performance of up to 90% efficiency. Due to the advanced PFC control, the T-4008 has low THDi <4% and high input power factor >0.99, resulting in low total cost of ownership (TCO).

The T-4008 is available in capacities from 160kVA to 500kVA with different cabinet sizes. With multiple digital control modules, such as DSP, MCU and CPLD, the T-4008 can be non-prioritised paralleled up to 8 units to lower operating costs without compromising reliability, performance and availability.
