Double conversion topology (on-line) is a basis for UPS designed for continuous power protection from all eight power problems: power failure, undervoltage, overvoltage, frequency variation, voltage harmonics, voltage distortion, high-frequency transient, power surge (with galvanic isolation). It ensures a consistent quality of power supply regardless of disturbances in the incoming mains. The output voltage is entirely regenerated by a sequence of AC to DC conversion followed by DC to AC conversion in order to create power supply without any electrical in-terference. Double conversion UPSs can be used with any type of equipment as there is no switching when changing over to battery power.

  • Protect 4 10 - 1300 kVA 2019

    Information about the updated model TSL Protect 4 (2019MY) will be available soon. Contact our Representative Offices and Partners in your area.  

  • Protect 5 MOD SUBRACK

    The rack modular, scalable, hot-swappable, online double conversion UPS ranging from 10 to 40kVA/kW, with its flexible configuration of 3/3, 3/1 and 1/1, and its compact structure, is the ideal choice for small and medium data centers. 7” color touch screen LCD with integrated bypass.

  • Protect 5 MOD

    The TSL Protect 5 Modular UPS with separated components also called decentralized technology is the only possibility to work without the risk of a “single point of failure”. Each UPS module has all the electronic-rectifier, inverter, static bypass switch, back-feed protection, battery fuse and control logic LCD display to garranty autonomous operation. 6-50kVA (1/1)(3/1) & 20-800kW (3/3)

  • Protect 3 10 - 1000 KVA with transformer

    The TSL Protect 3 UPS with transformer version  is designed for healthcare and industry applications. The high-quality online UPS of Vision can be provided with a galvanic isolation transformer, wich means that the electric circuits before and after the UPS are not connected physically, but via an electromagnetic field. This increases the reliability of the protection essentially. Spikes and disturbances can not pass the galvanic isolation transformer.

  • Protect 2 10 - 120 kVA

    The TSL Protect  2  series is our best “price-performance ratio“ 3/3 phase UPS. Based on our modular UPS technology, we are able to offer extremely small UPS 10-120 kVA solutions. A combination of our modular based UPS with a special DC/DC converter, the TSL Protect  2 UPS can work with a battery voltage of only 192 to 240Vdc (adjustable). This reduce space, batteries and price. Up to 4 TSL Protect  2 systems can be connected in parallel to get maximum power capacity. Only one battery is necessary with the parallel mode.
