Flexa 200/400-400

Three Phase Uninterruptible Power Supply 20kVA – 640kVA

Flexa 200 is a compact and modular UPS using a smart technology 3P input/output. It provides a pure sine wave with 96% conversion efficiency. Our technology offers a 0ms transfer time (from grid to batteries), integrates the static switch function, limited boost capability (to trigger downstream breakers while protecting upstream ones) and is easy to maintain (24kg hot-swappable modules):

Always powered

Flexa 200 operates without master/slave configuration, includes a redundant communication BUS and is IPC9592B certified. Efficient battery management makes it possible to always be ready to secure loads thanks to fast battery charging (up to 17kW), low ripple voltage and different charging modes.


Flexa 200 can be configured in 50Hz or 60Hz and also exists in 3P to 1P topology (Flexa 200 – 400/230). Cabinets can be customized on-demand, modules can be integrated into third-party cabinets or reused existing ones. Everything to be as flexible as possible.


Flexa 200 is used in many applications to protect IT loads in data centers and edge computing sites. Flexa 200 is also used and suitable for industrial, renewables, oil and gas, power utilities and in harsh environment (up to IP54).
