Reliable system technology
UPS ENERTRONIC modular SE – 10 to 1000 kW
Developed for the highest requirements in mission-critical processes
Disruptions or failures in the area of electricity supply can have far-reaching and financial consequences - in almost all areas of the economy. Especially in mission-critical areas such as IT, data technology, telecommunications, process automation, infrastructure (including equipment & transport), as well as the gas, oil and petrochemical industries, a reliable, continuous supply of electrical energy is essential. Highly available, uninterruptible power supplies (UPSs) should be used here.
At the same time, the seamless integration of UPS systems into intelligent power grids (smart grids) is becoming increasingly important. This is particularly true in conjunction with systems for the (intermediate) storage of energy generated from renewable sources and/or the possibility of peak shaving.

UPS ENERTRONIC modular SE – Maximum availability and lowest MTTR (Mean Time To Repair)
The ENERTRONIC modular SE combines the benefits of very high reliability and a very low mean time to repair (MTTR) to create a UPS system with the highest possible availability.
By using only the highest quality components, over specifying critical components and ensuring the design values reliability before cost, Benning has created a UPS with industrial grade reliability. When such reliability is combined with the repair and maintainability benefits of true “hot swap” modularity that can replace an entire UPS module in less than 10 minutes you have a UPS with “six nines” (99.9999 %) availability.
No Single Points of Failure
By designing redundancy into each critical circuit in each module, by incorporating “multi-master” technology into each module that allows all modules to automatically operate as either the master or a slave, and by decentralising the parallel architecture of the modules, Benning has designed a UPS system with no single points of failure.
“Hot Swap” modularity to 1,000 kW
Power capacities up to 1,000 kW can be achieved by paralleling UPS modules and cabinets. Each module can be up to 40 kW (cos(ϕ)=1) and automatically parallel with each other in either a parallel capacity or parallel redundant mode.
Uncompromising design, designed for maximum energy availability and economical operation
The ENERTRONIC modular SE UPS system is perfect for
- Excellent voltage stability
- UPS classification VFI-SS-111 (according to IEC / EN 62040-3)
- No single points of failure
- Max. efficiency: 96 % in double-converter mode, 99 % in SE mode
- Small space requirement (600x800 mm), back-to-back installation possible
- Safe and reliable operation
- Excellent control characteristics for high voltage stability
- Electronic transfer switch (EUE) and internal service bypass
- Black start function
- Upgradeable to a hybrid UPS energy storage system
Up to 99 % efficiency
Power capacities up to 1,000 kW can be achieved by paralleling UPS modules and cabinets. Each module can be up to 40 kW (cos(ϕ)=1) and automatically parallel with each other in either a parallel capacity or parallel redundant mode. The parallel mode is determined by the size of the load and is parallel redundant if it can be and parallel capacity if it has to be.
If the highest possible efficiency is more important than vol¬tage and frequency quality the user can opt to operate the ENERTRONIC modular SE in its “Super Efficiency” mode. In the SE mode, operating efficiencies of 99 % are achievable.
Downtime of less than 13 seconds per year
The ENERTRONIC modular SE achieves an outstanding availability of 99.99996 %, often referred to as "six-nines" reliability
Six-nine reliability
Due to the high number of system components in a modular UPS system, we assume a Mean Time Between Failures (MTBF) of 500 000 hours in our equation below.
However, since each UPS module in this topology represents a complete and fully functional power supply system that can be hot-swapped in less than ten minutes while the entire system is in operation, the Mean Time To Repair (MTTR) is one very impressive value of only 0.17 hours.
The following therefore applies to system availability:
Availability = MTBF / (MTBF + MTTR)
= MTBF / (MTBF + MTTR)
= 500 000 / (500 000 + 0.17)
= 500 000 / (500 000.17)
= 99.99996 %
= 0.21024 minutes / year

Power density of 415 kW/m² (Stand area 600 x 800 cm)
With its top ventilation (rear ventilation available as an option) and front access only maintainability, the ENERTRONIC modular SE can be placed against a wall or in a corner etc.
This minimises the system’s operational footprint and gives it the class leading power density of up to 415 kW/m².

The UPS system is scalable and can grow with your requirements
If the required power increases or decreases, modules can be added or removed very easily
Remote Monitoring System MCU 3000
Components for economical operation and maximum reliability
Reporting and monitoring functions
MCU 3000 signalling and monitoring unit
Continuous and economical operation of these systems requires that they are analysed and maintained with the help of powerful control and monitoring systems. BENNING provides the remote monitoring system MCU (Monitoring Control Unit) for this purpose.
The controller monitors the entire power supply system and controls power management, among other things. At the same time, it significantly reduces the time required for installation or maintenance, for example, thanks to automatable event-controlled processes. Proactive services are triggered in good time before major damage occurs.
Flexible power extension
“Pay as you grow” Scalability
It’s not always easy to predict the size a critical load will be in, say, 10 years time and if a UPS is over-sized or under-sized, valuable capex is being wasted.
To eliminate the costs associated with significantly over-sizing or under-sizing the UPS at “day one” an ENERTRONIC modular SE UPS system should be installed.
Only the exact number of modules needed to provide the required system capacity (or redundancy) need to be installed at “day one” and as the critical load increases, or decreases, so modules can be quickly added to, or removed from, the system to ensure that the UPS system is always sized to meet the needs of the critical load.
Highest power quality
Highest power quality
Each ENERTRONIC modular SE UPS module is a highly efficient double conversion, serial on-line UPS (VFI-SS-111). By supplying the critical load via the ENERTRONIC modular SE’s rectifier and inverter the quality of voltage and frequency experienced by the critical load is significantly improved.
The ENERTRONIC modular SE’s rectifier incorporates 3 level IGBT technology, which means low mains input distortion and active power factor correction. The ENERTRONIC modular SE’s input current total harmonic distortion (THDi) is an impressive ≤ 3 % and its typical power input factor is an equally impressive cos(ϕ) ≥ 0.99.
Each UPS module comprises:
- Three-phase rectifier with IGBT-3-Level technology
- Three-phase inverter with IGBT-3-Level technology
- Electronic switching unit (static bypass switch)
- Redundant regulation/control unit
SE mode
Super Efficiency" mode (SE mode) - efficiency of up to 99 %
In this mode the critical load is fed via the static bypass line until the voltage and/or frequency of the mains moves outside of pre-set tolerances. At this point the critical load is break-free transferred onto the UPS inverter and is therefore fully protected from damaging mains borne disturbances including brown-outs and black-outs.
Automatic TCO and availability optimisation
The user selectable and configurable power optimisation mode automatically and simultaneously minimises total cost of ownership (TCO) and maximises system availability. It achieves this by using its inbuilt intelligence to place any individual modules in excess of the number needed to guarantee the required level of power protection into a “sleep” mode.
All modules in this “sleep” mode remain fully ready to instantaneously provide power to the critical load should the need arise (e.g. in the event of a load increase) but will not be wasting energy by unnecessarily switching power. This means that the system is capable of automatically and intelligently delivering class leading system availability AND the lowest TCO.
Upgradeable to a hybrid UPS energy storage system
The good news for all operators of ENERTRONIC modular SE UPS systems is that these systems can be upgraded to include energy storage functions.
