Your DRUPS systems can be configured as N, N+1, N+2 or 2N to meet your criteria.

Various configurations are possible at low or medium voltages as Single Output System or Dual Output Sytem, Distributed Redundant, Isolated Redundant, etc.

Below, you will find some of the examples of EURO-DIESEL's configurations.

Parallel Systems at LV or MV

Parallel LV Configuration

LV Parallel Systems


Parallel systems comprise of two or more units operating jointly 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 works.

Parallel MV Configuration

MV Parallel

An increasing number of customers today require multi MVA power for their critical loads. Various electrical system configurations can be obtained, but the parallel systems are the most common requirements above all. Paralleling systems at low voltage has technical limitations on the busbars and the circuit breakers' sizes, especially on currents, for  both rated and short-circuit conditions.

The solution consists of adopting an MV configuration since, for a given output power, 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 MVA solution. MV configurations come in two versions; Either with a step-up transformer or with an MV alternator.

Of course, an MV configuration is the ideal solution when the load directly requires an MV supply or when the downstream distribution can only be done in MV.




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

IP Star Configuration

The IP Star DRUPS configuration has been first introduced to protect critical loads of 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 to the other units 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

EURO-DIESEL 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 bus. IR is also a modular design with one isolated redundant unit that serves to provide redundancy to a bus, where the other units are able to transfer their loads to.
