2.1 TECHNOLOGY
Protect D. is an uninterruptible power supply (UPS) for rack mounted loads such as
PCs, workstations, servers, network components and similar devices, consisting of:
• Network filter with surge protection (device protection / Class D) and mains
back-feed protection
• Rectifier with PFC-logic (power factor correction unit)
• Separate input possibilities for rectifier and bypass (DUAL or SINGLE input)
• Separate intelligent battery charger with switch mode power supply technology
• Sealed system battery with maintenance-free design for energy storage in rack
technology with downstream DC / DC converter unit
• 3-level IGBT inverter for continuous supply to the connected loads with
sinusoidal AC voltage
• Automatic, electronic bypass(SBS) as an additional passive redundancy
SBS = Static Bypass Switch
• Removable terminal unit with outlets to IE60320, fitted with an automatic
locking mechanism
• Manual bypass for maintenance and service purposes (with automatic static
bypass activation, when operated)
• Parallel operation for the purpose of preparation of active redundancy or
to increase power
• Control unit based on digital signal processor technology
• Multi-lingual LCD display designed to display remaining time and logs in
real time
