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 drawers 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:

3. Technological description
The command board is connected to a control panel with display from which it is possible to verify the status and setups
of the EPS and to a communication interface with RS-232 and SNMP connection, dry contacts and logical contacts. It is
possible to access all the EPS functions from the control panel and communicate through any of the interfaces present
thereby guaranteeing the redundancy of the peripherals as well. In installations with three separate single phase line on
output, it is possible to manage each line independently through the software. For example, it is possible to prioritise the
autonomy of one of them during battery operation. A bypass input line separated from that of the mains input makes it
possible to supply the bypass with a second power source (the neutral wires of the two lines must be in common).
The technology used in the hardware and the firmware of the EPS represents the current state of the art.
A sophisticated microprocessor-type control optimises the performance both on the Booster/PFC side and on the output inverter. The recharge curve of the battery has been designed to get the maximum useful life and have the greatest
autonomy possible if the main power goes off. The electronic boards are entirely assembled on LEGRAND automated
lines and tested to the highest quality standards. Every device goes through an extended period of operation at full load
before being sent to the customer.
3.2 Features
Modular-redundant architecture
The modular-redundant architecture is the best solution for protecting the nerve centres of a company and has the following advantages:
- there is one control of the devices supplied;
- modular expandability;
- module redundancy;
- easy maintenance;
- low running cost;
- compactness.
Efficiency
Trimod MCS concentrates particularly on both the energy absorbed from the mains and the energy provided to the load.
They are characterised by high efficiency (up to 96%), PF on input>0,99, THDi <3%.
The advantages of a high efficiency are:
- reduction of the power absorbed from the EPS but not supplied to the load and transmitted to the environment as heat;
- less heat loss transmitted to the environment means reducing the need for ventilation or air conditioning systems in the
installation site;
- no power factor correction cost and so no increase in charges;
- no need to increase the size of any generator upstream of the EPS.
Expandability
Most EPS systems on the market are of the non-modular and non-expandable type thus requiring an initial upscaling of
the system to make future expansions possible.
The advantages of an expandable system are:
- optimisation of investments for EPS, making them adequate for the current requirements without precluding future
expansions and avoiding wastes of energy;
- increase in the efficiency of the system thanks to proper sizing.
Reliability
To obtain a level of redundancy with traditional EPS, it is necessary to put at least two in parallel thereby doubling the
power acquired, the space occupied and the electricity consumed. Trimod MCS modular architecture makes it possible to
have redundant configurations within a single cabinet.
The advantages are:
- a redundant modularity EPS can be configured as a power redundant N+X system. Even in the case of a fault in a
module, the equipment continues to function avoiding any downtime;
- clear indications and a large display make it possible to find the fault more quickly;
- the modular architecture makes it possible to speed up the solution to problems through the simple replacement of the
faulty module without interrupting the service;
- high percentage of faults resolved at the first attempt.
Power module
The high-efficiency single phase module, available in three power sizes of 3400 VA (PM4), 5000 VA (PM6) and 6700 VA
(PM7) respectively, and is mainly made up of the following functional blocks:
- command and control logic (managed by a microprocessor);
- PFC rectifier/booster;
- inverter;
- battery charger;
- automatic bypass.
In each power module there is a microcontroller that can oversee the main functions of the individual unit, monitor its
correct operation and flag up any malfunctions.
The power module is Plug & Play to make the power expansion and any maintenance operation easier. Every module is
put in parallel with other identical ones until reaching the power of the EPS.
The modules are independent of each other and can function even if there is a fault in one of them. At the front of the
module there is a multicoloured LED with traffic-light code green-yellow-red, making it possible to identify the operating
status of the electronic unit quickly.
14
The power modules are housed on shelves also called “tunnels” that can house three modules.
The block diagram of the power module is the following:
Trimod MCS
User manual
Batteries
The battery modules are designed for easy insertion into the dedicated cabinet and they do not need any operation for
their connection. A drawer consists of five 12V-9Ah batteries, connected in series and thanks to the Plug & Play connection it is easy to extract and insert it in the cabinet.
The nominal battery voltage for the Trimod MCS is 240Vdc, therefore a complete branch consists of four battery drawers
(for a total of twenty 12Vdc batteries) that form what is called KB (Battery Kit).
In order to ensure the maximum level of safety, the voltage of each drawer is properly isolated into two branches of 24 V
and 36 V and it is only restored when the drawer is completely inserted into its housing.
This allows conformity with the standard EN 62040-1 on electrical safety that requires the use of adequate protection and
particular care when handling dangerous voltages above 50 Vdc where direct contact is possible.
The battery operation autonomy of the EPS can be increased by adding more battery drawers in multiples of four, using
both the seats in the EPS cabinet if available, and the seats in the additional modular battery cabinets.
Digital display and alarm display
Trimod MCS is managed by a microprocessor-type command board (according to the version) and it has a backlit LCD
alphanumeric display with twenty characters on four lines.
The display is incorporated in the control panel where there is also a high-brightness operating status indicator with
traffic light type green-yellow-red.
Five keys situated near the display enable the user to display the operating data, set the operating parameters, analyse
the status of the individual power modules, select the language in which the messages are to be displayed and carry out
a guided set of functional tests and procedures.
BCM - Battery Charger Module 3 108 51
The additional battery charger module works in parallel and in sync with the battery chargers in the power modules and
it is managed by the same algorithm that governs the recharging cycle. Every additional battery charger module provides
up to 15A of charge current that are added to the current of the battery chargers inside the power modules. Every power
module can provide up to 2.5A of charge current. This guarantees a reduction of the charge time in installations requiring
long autonomies and increases the availability of the UPS after a black out. During operation, the module takes current
from the input phase where it is installed.
It is possible to install any quantity of BCMs as long as there is at least one power module and enough empty slots inside
the EPS cabinet. All the information regarding the operating status of the BCM is given by the LED on the front of the
module and by what is shown on the EPS display.
The module is managed by a microprocessor to optimize performance and reliability. It is recommended to install it together with a battery cabinet with capacity exceeding 60 Ah.
ECO MODE
One functioning mode of Trimod MCS is called “eco mode”. With this mode it is possible to save energy while guaranteeing uninterruptability of the power supply to the load connected. During the functioning in eco mode, the load
is powered directly from the electrical mains through the automatic bypass circuit inside the power modules. This
means that the output voltage and frequency are the same as the mains. The advantage obtained in the eco mode is
a greater electrical efficiency and consequently a reduction in consumption. If the output voltage leaves the window
of tolerance (-20% / +15% of the voltage set on the output), the EPS actuates its inverter stage and powers the load
with the energy stored in the batteries. The autonomy during the battery operation depends on the configuration of
the UPS (nominal power, battery capacity) and on the percentage of load applied. When the mains are back within the
tolerance values, the EPS switches automatically back to the eco mode. It is possible to change the operating mode
between on-line and eco mode (and viceversa) both with the EPS on and with the UPS off (in this case entering the
Service Mode).
