ENERTRONIC modular (10 – 480 kVA) Three phase modular UPS system for your mission-critical Business Applications

BENNING has been supplying modular DC power solutions for IT, telecom and industrial applications for more than 25 years. These DC systems are very reliable as they consist of parallel operating hot-plug DC power modules with n+1 redundant configuration. This design allows easy and rapid replacement as well as upgrade or downgrade of the power capacity following any change in the load requirements.

More and more customers are now demanding a similar modular, n+1 redundant, solution for their UPS requirements.
Bringing into market the ENERTRONIC modular UPS-System, BENNING followed these customers requests. ENERTRONIC modular UPS systems are now available with steps between 10 kVA and 480 kVA (440 kVA n+1 redundant).

ENERTRONIC modular - the advanced UPS technology

Verfügbarkeit, Kosten, Enertronic modular

When making a decision to invest in UPS systems for mission critical applications availability and total cost of ownership (TCO) have to be considered. However, as you can see from the chart ohter product characteristics must be considered to make the right decision for the best possible UPS solution.

High Efficiency under partial load conditions

Energy costs, the major part of UPS life-cycle costs, are directly related to the efficiency characteristic of the UPS system. In contrast to traditional UPS systems with „poor“, efficiency under partial load conditions, ENERTRONIC modular UPS systems have been designed to provide their highest efficiency between 30 % and 100 % load. Higher efficiency at partial and rated loads results in considerable energy and CO2 emission savings.

Less consumption in electrical energy and savings in CO2 emissions

The figure shows annual savings on electrical energy and CO2 emissions of a redundant (n+1) 60 kVA ENERTRONIC modular UPS system compared with a traditional redundant monoblock UPS (2 x 60 kVA). The identical load for both systems is 50 kVA (0.8 power factor). Annual savings on electrical energy are 16560 kWh and 8.51 t of CO2 emissions.

Parallel and redundant

Very often traditional UPS systems operate as stand-alone systems without any redundancy. System component faults can cause downtime of mission critical loads with very costly consequences (single point of failure).

No Single Point of Failure

ENERTRONIC modular UPS systems are based on parallel operating hot-plug power modules. Each module represents a complete double conversion UPS system with three phase input three phase output and static by-pass. Maximum availability is achieved by combining the parallel operating modules with n+1 redundant design.

Pay as you need - Flexible output power scalarity

In comparison with single bloc UPS systems with high initial costs the advanced ENERTRONIC modular concept allows the user to scale the output power in steps and to adapt the UPS system to changing power requirements. With power modules of 10 kVA, 20 kVA and 40 kVA a wide range of UPS system solutions can be designed.
The addition or replacement of power modules can be achieved without additional work on site. The load continues to be supplied by safe UPS power. No load transfer to mains is required. The software within the ENERTRONIC modular UPS system integrates the new modules automatically.

Tier Classification Tier I – Tier IV

USV Anlagen Tier 1 – Tier 4

Tier Classification System

Uptime Institute New York has created the international Tier classification system for the infrastructure of data centers. According to this topology four Tier levels (I-IV) are used. ENERTRONIC modular UPS systems with n+1 redundant parallel architecture are Tier III classified and two separate redundant ENERTRONIC modular UPS systems with two different input sources (bus bar A and bus bar B) are Tier IV solutions.

Flexible battery configurations

The ENERTRONIC modular UPS can be supplied with common battery, group battery or single battery configurations.
Maximum system availability is achieved by group or single battery solutions. Depending on UPS output power and autonomy, batteries can be installed in cabinets or separate battery racks.

Optimised fan life expectancy and simple maintenance

UPS Module Enertronic Modular 20kVA

Optimised fan life expectancy and simple maintenance

ENERTRONIC power modules are equipped with front access fans which can be easily replaced during normal UPS operation. These fans are mounted in the „cold“ air inlet behind the front plate. The „hot“ air leaves the power module at the rear.
The expected life time of fans which are mounted in the „cold“ air zone is much better than for fans positioned in the „hot“ air zone at the rear of the cabinet.

Lower floor space (footprint) requirements

ENERTRONIC modular vs. traditional redundant mono bloc UPS systems floor space requirement

Floor space (footprint) requirement of parallel redundant UPS systems

The single, space saving cabinets of ENERTRONIC modular UPS systems need less than one third of the floor space when compared to traditional redundant two cabinet UPS systems. Traditional UPS systems often require access for service and repair at the sides and the rear. ENERTRONIC modular UPS systems only require front access. With the parallel architecture, only one cabinet is required for ENERTRONIC modular UPS systems. This cabinet can be upgraded by simply inserting additional power modules. No extra space or cabling is required.

Unity power factor and low THDi

ENERTRONIC modular with near unity power factor and 5 % THDi avoids expensive oversizing of Gen-sets

Unity power factor and low THDi

The harmonic pollution (THDi) on the input current of a traditional UPS with 6-pulse thyristor rectifiers is about 33 %. If Gen-sets are used, they have to be oversized by 2.5 times the UPS output power. With 12-pulse thyristor rectifiers Gen-sets need 2.0 times higher output power. ENERTRONIC modular UPS systems with their „clean input“ (THDi < 4 %) require Gen-sets with only 1.4 times the rating of the UPS output power.

Lower Operating Costs (TCO) / Demand-oriented investment

Total cost of ownership (TCO)

Total cost of ownership depends on capital and operating costs as well as installation, footprint and maintenance costs. In comparison to traditional UPS systems the advanced modular hot-plug design of ENERTRONIC modular UPS systems results in lower operation, installation, upgrade and maintenance costs.

Power upgrade

Compared with traditional UPS systems the scalability of ENERTRONIC modular UPS systems allows the output power to grow in-line with increasing demand. This eliminates the high initial capital cost of purchasing power capacity that is not required at the earlier stage of installation. During the entire life-cycle, power capacity upgrading keeps the cost of ownership low. Operating costs can be optimised if each of the parallel redundant power modules delivers between 50 % and 100 % of their nominal output power. It is therefore important to pay attention to the UPS system efficiency under partial load conditions.
