Midi / Maxi series UPS devices ensure maximum protection and power quality for any type of load, especially for mission critical applications, security systems and electro-medical equipment, industrial processes and telecommunications. Midi / Maxi is an on-line double conversion UPS (class VFI SS 111 in accordance with IEC EN 62040-3) with a transformer isolated inverter. The Midi / Maxi range includes three- phase input and single-phase output versions from 10 to 100kVA, and three- phase input and output versions 10 to 800kVA. The three-phase versions are available from 10 to 200 kVA with a 6-pulse thyristor rectifier and, for some powers, with 12-pulses. From 100kVA to 500kVA, the HP versions with IGBT rectifiers offer the best solution for low harmonic distortion of input current THDi and for the single input power factor (see Midi / Maxi HP chapter); products with 12-pulse thyristor rectifiers in the same power range are available upon request. From 600 to 800kVA, the solutions are offered are equipped with a 12-pulse rectifier with and without a filter to reduce harmonics (optional).
