MASTER MPS series UPS provides maximum protection and power quality for critical loads, including data centres, industrial processes, telecommunications, security and electro-medical systems. The UPS is an On-line double conversion UPS (VFI SS 111 - IEC EN 62040-3) with a transformer isolated inverter.
The MASTER MPS range includes three-phase input and single-phase output versions from 10 to 100kVA, and three-phase input and output versions from 10 to 800kVA. Three phase MPS models from 10 to 200 kVA are available with a 6 or 12-pulse thyristor-based rectifier. From 100 to 600 kVA, the Master HP series has an IGBT-based rectifier, to provide lower harmonic input current distortion (THDi) and a high input power factor (see Master HP section). From 600 to 800kVA, Master MPS have a 12-pulse rectifier and optional harmonic filters.
