2.1 Trimod® Technology
Congratulations on your purchase of a UPS Trimod® product from LEGRAND®.
Thanks to the UPS Trimod® your critical equipment will be protected by a constant and reliable supply of power for years
to come.
LEGRAND® has developed a project that is both innovative and unique, creating Trimod®, the UPS with a power range
of 10, 15, 20, 30, 40 and 60 kVA capable of adapting itself at any time to the changing requirements of protected loads:
greater power, longer autonomy, redundancy.
The basic concepts of the Trimod® project are, in fact, modularity, expandability and redundancy which, besides o ff ering
maximum reliability, are also the guarantee of a considerable economic saving.
Trimod® is a modular uninterrupted power supply unit with individually programmable basic modules so you can have
the input/output con fi guration you want. In this way it is possible to control three- and single-phase voltage in input and
output to have, as preferred the classical three/three, three/single, single/three and single/single lines but it is not limited
to just this: you can also have single- and three-phase lines in output simultaneously or two or more single-phase lines
also of di ff erent powers (on request).
And then, for each con fi guration it is possible to obtain redundancy, both complete and partial by which we mean that,
for example, a normal (or redundant) threephase line plus a redundant (or normal) single-phase line can coexist in output.
A microcontroller mounted in each basic module is capable of monitoring the main functions of each single power unit,
monitoring its correct operation and signalling any malfunctions.
The modularity philosophy has also been used for the batteries which are supplied in single pull-out boxes. THDi = 3% -
Power Factor > 0.99 – High Yield – High Reliability – Easy to install and service.
2.2 Features
Redundant modular architecture
Redundant modular architecture is the best way to protect a company’s critical points.
Advantages:
- There is just one control of the devices powered
- Modular Expandability
- Module redundancy
- Easy to service
- Low running cost
- Compact size
Yield
The UPS units of the Trimod® line place particular attention on the energy taken from the mains and that supplied to the
user points. High Yield (>94%), PFC in Input >0.99, THDi 3%.
Advantages:
- Increasing the yield means reducing the part of power absorbed by the UPS but not supplied at the load and transmitted
to the environment in the form of heat.
- Less heat dispersed in the environment means reducing the use of aerating or conditioning systems on the installation premises.
- PFC in input means no rephasing costs and consequently no increased rates.
- No need to oversize a generator (if used) upstream from the UPS
Expandability
The majority of UPS units on the market is neither modular nor expandable and therefore initial oversizing of the system
is necessary to ensure future expansions (which might not even happen).
Advantages:
- The modular and expandable Trimod® systems allow optimisation of the investments made in UPS units, adapting
them to actual requirements without preventing future expansions and avoiding an unnecessary waste of energy.
- System yield is increased thanks to correct sizing
Reliability
To have a redundancy level with traditional UPS units it is necessary to put at least 2 in parallel, thus doubling the power
bought, the space taken up and the electricity consumed. Instead Trimod®’s modular architecture allows redundant
con fi gurations inside just one single cabinet.
