DRUPS systems can be configured as N, N+1, N+2 or 2N to meet your required levels of maintainability and fault tolerant designs.

Various configurations are possible at low or medium voltage as Single UPS Output Systems or Short Break Sytems, Distributed Redundant, Isolated Redundant, etc.

Below, you will find some of the examples of E1 DYNAMICS's configurations and capabilities.

Parallel Systems - LV or MV

Parallel LV Configuration

LV Parallel Systems

 

Parallel systems comprise of two or more units operating together to feed a common critical path. Parallel systems are  for loads larger than otherwise possible with a single unit. Parallel systems are designed at low and medium voltages. By paralleling multiple units, a redundant configuration can be obtained.

A redundant configuration has an even higher reliability and provides more flexibility during the execution of preventive maintenance.

Parallel MV Configuration

MV Parallel

An increasing number of customers today require multi mega Watt UPS power for their critical loads. Various electrical system configurations can be obtained, but the parallel systems are the most common above all. 

 

With a MV solution, the current is inversely proportional to the voltage.  In practice, this means that 20 or more units can be operated in parallel in order to obtain a multi MW solution.  MV configurations come in two versions; Either with a step-up transformer or with an MV alternator.

 

Both parallel configurations can be designed for both concurrent maintainability and fault tolerant conditions to meet some of the industries most stringent design requirements.

 

 


 


Distributed Redundant

Distributed redundant Configuration

Distributed Redundant Configuration

This is a modular design where individual systems share the redundancy. This allows the end-user to create a multi MVA facility at low voltage or to obtain a concurrently maintainable configurations.


IP Star

IP Star Configuration

Distributed Redundant Configuration

The IP Star DRUPS configuration has been first introduced to protect critical loads for high power ratings (above 5 MVA) with the objective to maintain a distribution system at low voltage, instead of medium voltage.

In this configuration, each NO-BREAK KS® unit protects its own load and is downstream connected through the IP Choke.

The redundancy is simply given by the connection between each UPS unit’s output and a central point called the Star Point, which is physically arranged in a ring formation (IP Bus): when one unit is offline, the remaining units take over the stranded load. The QDR switch of the offline unit is used for short-circuiting the IP choke to minimise the voltage drop.

Other Configurations

E1 DYNAMICS offers, amongst others, Isolated Parallel (IP) and Isolated Redundant (IR) configurations. IP is a modular design where all systems share their redundancy but supply into the same output ring or star bus. IR is also a modular design with one isolated redundant unit serving to provide redundancy to a bus, available to the other units where they are able to transfer their loads.
