Protect Flex

Industrial UPS

10 – 40 kVA
1/1, 3/1 or 3/3 phase

up to 4 UPS in parallel operations

A new concept of UPS systems that combines a modular architecture based on 10 and 15 kVA/kW hot-swappable power modules, transformer-less and IGBT-based, with a customizable set of options.

As industrial grade fully modular UPS, the system is a simplified, flexible and highly cost-effective UPS which can cope effectively with harsh environmental conditions, with an IP43 rating protection. Protect Flex is designed to maximize savings in terms of footprint and power installed (kVA).

Protect Flex’s innovative design encapsulates AEG PS’ unmatched expertise in securing power for industrial applications where flexible, reliable and robust solutions, with customized options, are needed: chemical and petrochemical industry, power generation, mining, transport application applications, healthcare environments (group 0-1 according to IEC 60364-7-710).

  • Maximize savings in terms of footprint (m2), power installed (kVA), electrical system (cabling and protection devices), security (MTTR and MTBF) and most importantly, power management (kW and cost).
  • Scalable architecture reduces CAPEX and optimizes OPEX costs. The power modules use the latest IGBT technology with a low input THDi and almost unity input power factor, even when a low percentage of load is applied: no need of any additional power-consuming filter.
  • Direct connection to the grid, simpler to install.
  • Fast recharge time even with higher capacity: for long runtimes, the UPS can be installed with one (or more) optional 15 A battery charger.
