The UPS systems of the Master MPS series guarantee maximum protection and highest quality in the supply of mission-critical loads such as data centres, industrial processes, telecommunication systems, security systems and electromedical equipment. The Master MPS is an uninterruptible double-conversion ON LINE system of class VFI-SS-111 according to IEC EN 62040-3 with output transformer. The Master MPS series includes versions with three-phase input and single-phase output with 10 to 100 kVA and versions with three-phase input and output with 10 to 200 kVA. All versions are equipped with 6-pulse thyristor rectifiers, with or without or without filters to reduce harmonics.
