CE+T Flexa 200 Modular UPS Systems Scalable 20–640 kW Critical Power
Flexa 200 is a modular UPS platform for larger three-phase critical-power systems where uptime, serviceability, and future expansion must all be designed into the architecture from the start. Built around 20 kW hot-swappable UPS modules, it allows capacity and redundancy to be scaled step by step from smaller initial installations to high-power multi-cabinet systems, without replacing the original platform or forcing a complete redesign later.
What makes Flexa 200 particularly distinctive is that each module includes its own static bypass, while the system can also be built with a Smart Bypass module that enables efficiencies of up to 98% even at higher power levels. The platform can be supplied from two independent feeders, AC1 and AC2, while maintaining the same total system capacity, which adds further resilience and design flexibility for demanding installations. Combined with true 0 ms transfer to battery, no master/slave dependency, redundant communication, and flexible 3-phase input/output architecture, Flexa 200 fits industrial, telecom, utility, and infrastructure environments where long-term power architecture matters more than simply adding backup time.
Flexa 200 modular UPS – Key features and advantages
Designed for scalable three-phase critical-power systems where maintainability, resilience, and future expansion are as important as backup performance itself.
Modular 20 kW architecture
Built around hot-swappable 20 kW power modules, Flexa 200 allows capacity and redundancy to be added step by step without replacing the original system platform.
Static bypass in every module
Each UPS module includes its own static bypass, improving system resilience and helping maintain continuity during service events or internal module-level faults.
Smart Bypass for high efficiency
The optional Smart Bypass module can increase operating efficiency to up to 98% at higher power levels, making the system more attractive for larger installations with continuous loads.
Dual-feeder power architecture
Flexa 200 can be supplied from two independent feeders, AC1 and AC2, while maintaining the same total system capacity for greater design flexibility and power-path resilience.
Flexa 200 variants and configurations
Compare the main Flexa 200 platform variants, system architectures, and expansion options within the family.
Flexa 200 400/400 and 400/230
The Flexa 200 family is available in both 3-phase to 3-phase and 3-phase to 1-phase versions, allowing the same modular UPS platform to fit different load architectures. The 400/400 version is intended for larger three-phase infrastructures and scales up to 640 kW, while the 400/230 version is designed for single-phase critical loads within three-phase infrastructures and scales up to 100 kW. Standard system options range from compact 20–60 kW battery-integrated cabinets to 160 kW and 200 kW configurations, while maintaining the same core Flexa 200 logic of 20 kW modularity, hot-swappable modules, and flexible cabinet-based deployment.
This gives Flexa 200 a broad deployment range without changing platform logic. Smaller systems can be built in compact cabinets with batteries in the same enclosure, while larger projects can use higher-capacity cabinets and parallel expansion up to 640 kW. A single controller can manage up to 32 × 20 kW modules, and matching battery cabinets in the same design language are also available. Typical cabinet dimensions such as 600 × 2100 × 800 mm keep the system compact for its power class, while custom configurations, including higher-IP cabinet versions, can be built for more demanding environments.
Flexa 200 400/400 with Smart Bypass
This version combines the standard Flexa 200 400/400 modular UPS platform with a dedicated Smart Bypass architecture that enables supply from two independent feeders, AC1 and AC2, while maintaining the same total system capacity. That is the key functional difference versus the standard 400/400 version. In addition to this dual-feeder resilience model, the SBP version can raise operating efficiency from the usual 96% up to 98%, making it particularly well suited for larger three-phase installations where both power continuity and operating efficiency matter.
Compared with the standard Flexa 200 400/400, the SBP version adds a dedicated 200 kW / 3U Smart Bypass module and introduces a different system architecture aimed at larger critical-power projects. Standard configurations are presented in 80, 160, 200, 400, and 580 kW, with 1 SBP used up to 200 kW, 2 SBPs for 400 kW, and 3 SBPs for 580 kW systems. This makes the SBP variant the stronger fit where the design goal is not only modular UPS protection, but also higher-efficiency operation and a pseudo A+B style dual-feeder architecture within one platform.
Core components and control elements
Explore the main building blocks behind the Flexa 200 platform, from power modules and Smart Bypass architecture to the control and monitoring layer that supports configuration, resilience, and system-level supervision.
Inview X + T4S control architecture
Inview X and T4S form the supervision and control layer of the Flexa 200 platform. Inview X provides the front-end for monitoring, alarms, and parameter access, while T4S handles backend control, settings distribution, battery functions, and communication with the Flexa 200 modules. The key advantage is that UPS operation does not depend on either controller as a single master, because the power modules continue coordinating through their own internal control logic.
This separation between control and power conversion improves resilience. Inview X gives the operator a clearer interface for configuration and diagnostics, while T4S manages broader system functions such as supervision, alarms, and battery-related control. If the front-end or backend controller becomes unavailable, the UPS can still continue operating because the core power stage remains active at module level.
Flexa 200 20 kW power modules
Each Flexa 200 system is built from 20 kW / 20 kVA power modules that can be used in both 3P→1P and 3P→3P architectures. The module platform supports a 408 VDC battery system, offers up to 17 kW charging power per module, and can scale to 32 modules in parallel within the wider Flexa 200 architecture. Conversion efficiency is rated at 96% in online operation, with 96% from batteries, while the internal design uses doubled DSP control and galvanic isolation to support resilience and stable module-level operation.
This module-level approach is what gives Flexa 200 its scalability and serviceability. Instead of relying on a single large power block, the system grows by adding identical 20 kW modules, allowing capacity, redundancy, and maintenance strategy to be built around the same core unit. The same module family is used across both 400/230 and 400/400 system variants, which simplifies platform standardization while keeping flexibility for different output architectures and battery-backed critical-load designs. The product page also positions the module as part of a platform designed for custom solutions, with optional Smart Bypass available at system level rather than as a separate module family.
Flexa SBP 200 kW – Smart By-pass module
The Flexa SBP is the dedicated 200 kW Smart Bypass module used in larger Flexa 200 400/400 systems. Its role is not to replace the UPS modules, but to add a higher-efficiency operating path and enable the dual-feeder AC1 + AC2 architecture that distinguishes the SBP-based system design. In normal conditions it supports operation at up to 98% efficiency, while outside tolerance the system transfers back to the Flexa 200 inverter modules to maintain a controlled pure sine output.
At system level, the SBP module is what turns Flexa 200 from a standard modular UPS into a more advanced architecture for larger three-phase projects. One SBP 200 kW module is used up to 200 kW, two SBPs are used for 400 kW, and three for 580 kW systems. Transfer behavior is designed around continuity, with 0 ms return from SBP to Flexa and a short transfer from Flexa to SBP. In practical terms, this makes the SBP module the key building block when the project requires both modular UPS protection and a pseudo A+B-style dual-feeder resilience model within one platform.
