3. Technological description
3.1 Trimod MCS technology
LEGRAND® has developed an innovative project that is the only one of its kind by producing Trimod MCS, the EPS with 3,
5, 7, 10, 15, 20, 30, 40, 60 and 80 kVA power.
The concepts underlying the project are modularity, expandability and redundancy in such a way as to offer maximum
reliability and to be the guarantee of considerable savings.
Trimod MCS is EPS designed in accordance with EN 50171 for the preservation of power supply in emergency and security
systems. Some of its features are:
- permanent overload capability of 120% in relation to the rated power;
- batteries with rated life expectancy of 10 years;
- battery polarity inversion protection
- protection against complete discharge;
- short circuit protection;
- high current battery charger for full charge time of 12 hours;
- IP20 metal enclosure according to EN 60598-1.
If the mains is available, the EPS output is enabled by default. It is possible to change this setting from the control panel.
If the mains input is missing, the output is supplied by the EPS in battery mode.
Trimod MCS is a modular EPS whose base module is single phase and can be programmed to obtain the desired input/
output configuration. It is thus possible to manage three phase and single phase voltages on input and output to have a
choice of the traditional three phase/three phase, three phase/single phase, single phase/three phase and single phase/
single phase. At the same time it is possible to obtain simultaneously single phase and three phase lines on output or two
or more single phase lines even with different power.
For every configuration it is possible to have redundancy that is both complete and partial. For example, one normal three
phase (or redundant) line can coexist with a redundant single phase (or normal) line on output.
The philosophy underlying modularity has also been applied to the batteries that have been supplied in individual draw-
ers that can be extracted and make installation and maintenance easier.
The EPS is controlled by one command board.
The command board (CM) and the power modules (PM) are identified by a unique address inside the system, as shown below:
