Protect 8.33
Industrial High Power UPS
Complete Systems
Protect 8. is a true on-line double conversion UPS classified as
VFI SS 111 according to IEC 62040-3.
• On-line operation ensures permanent service
• Microprocessor-driven control and command system
provides reliable power supply
• Battery management system boosts battery life and cuts
operating costs
• Broad range of output power ratings, battery autonomy
times and options meet complex industrial applications
needs
• High level protection for users and connected equipment
(high intermittent overload capacity; high level short
circuit strength)
• Excellent dynamic response easily high cyclic loads.
Unique Design
Protect 8. UPS configurations:
• Single systems
• Parallel systems
• Customized input/output voltages
• Text translations to any language.
Parallel operation for capacity and performance:
• Flexible Multi Master technology and Can-Bus communi-
cation up to 8 UPS to be connected in parallel for increased
power, redundancy or system upgrade
• Parallel UPS can be operated with separated or central
battery.
Key Features
