RT Series UPS Systems
Single Phase and Three Phase
RT UPS systems have been designed and built for industrial applications since 1985, in particular for the continuity of production processes and for industrial plant automation and control.
RT UPS systems can be found in numerous chemical and petrochemical installations, in steel and general metal production plants, glassworks, pulp and paper mills, textile and food plants, publishing, health care and in telecommunication and defence applications.
The RT UPS systems are quiet in operation, the design is compact and all features are well laid out. Low thermal dissipation, easy installation and many other characteristics make RT UPS systems ideal for use in computer room environments.
Many installations have been made in industrial, banking and university sites, in offices of many public utilities and private companies and they have been used in many applications supporting new technological solutions in office automation.
In addition to UPS systems from 10kVA to 400kVA for industrial applications, we offer a wide range other products:
- Inverters
- Rectifiers
- Frequency Converters 50/60Hz
- Mains Static Transfer Switches since 4 to 600kVA
- Feeders for cathodic protection

NOTES:
- Float voltage refers to VRLA batteries as example for data calculations only.
- At max auto boost charge voltage for vented lead acid batteries with input mains not less than -5%.
- An optional mains balancing isolation transformer will be necessary to convert 3 phase input to single phase output in the bypass circuit otherwise when the single phase load is transferred to the bypass the “R” phase carrying the bypass load current would create a serious unbalanced loading on the upstream DB protection.
- Typical 27% with 6 pulse fully controlled thyristor bridge rectifiers. We can supply optional filters or 12 pulse rectifiers to reduce to less than 10% the total harmonic distortion reflected into the input mains source.
- Optional isolation input transformer available. Supplementary metering available.
- Batteries enclosures available in style to match the appearance of the UPS system.
- Other colours available on request.
