Protect Flex Modular industrial-grade UPS, 10-40kVA

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

The system is an industrial-grade fully modular UPS, flexible and highly cost-effective. It 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 : chemical and petrochemical industry, power generation, mining, transport applications, healthcare environments (group 0-1 according to IEC 60364-7-710)


Key Features:

  • On-line double conversion UPSwith an internal modular design
  • Optional transformers (inbuilt or external cabinet) available to meet all types of voltage requirements as well as electrical isolation when needed
  • N+1 inbuilt power redundancy architecture
  • VFI SS 111 technology (up to 94 % efficiency)*
  • ECO Mode available (up to 98 % efficiency)*
  • Input PF > 0.99, THDi < 4 % (without additional filters)
  • Output PF up to unity and compatible with inductive or capacitive loads without derating
  • Ingress protection up to IP43 (more rugged environmental protection available upon request)
  • Integrated static and manual bypass lines
  • Parallel capability up to 160 kVA (4 x 40 kVA in parallel)**
  • 7" color Touch Screen graphic
  • Connectivity options: SNMP, Modbus, BACnet®
  • Phase configuration options: 1/1, 3/1 and 3/3
  • Large set of functional options to meet all specific requirements and challenging conditions

* Conditions apply
** According to the UPS system configuration


  • Tailor made, highly flexible and reliable power protection suitable for difficult environments.
  • 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 for any additional power-consuming filter.
  • Fast recharge time even with higher capacity: for long runtimes, the UPS can be installed with one (or more) optional 15 A battery charger.
