TECHNOLOGY

Congratulations on your purchase of a UPS ARCHIMOD

product from Meta System S.p.A..

Thanks to the UPS ARCHIMOD

your critical equipment will be protected by a constant and

reliable supply of power for years to come.
MetaSystem has developed a project that is both innovative and unique, creating ARCHIMOD

the UPS with a power range of 20, 40, 60, 80, 100 e 120 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 ARCHIMOD

project are, in fact, modularity, expandability

and redundancy which, besides offering maximum reliability, are also the guarantee of a
considerable economic saving.
Even the ARCHIMOD

BATTERY rack cabinet is modular with boxes for extremely simple

maintenance and battery Hot-Swap.
The ARCHIMOD

UPS guarantees the best load protection levels together with reliability and

redundancy. This is possible thanks to a modular architecture that has a 6.7kVA single-phase
power module as its basic element. The power modules are connected in parallel, phase by
phase, and should just one module fail only the power of that module on the phase involved is
lost. The UPS is controlled by 1, 2 or 3 boards, depending on the configuration. Each board can
control up to 6 power modules. If one of the control boards fails, only the modules it controls are
turned off and made safe while the UPS carries on working on-line with no interruption to the load.
Redundancy is therefore possible on a single phase (power module
failure) and inside the UPS (control failure). Hot-Swap replacement
of the power modules is also possible, turning the control off as
well as the set of modules connected to it without having to power
the load from the bypass line thus temporarily losing protection.
Even the modular ARCHIMOD

BATTERY boxes can be Hot-Swap

replaced without having to put the UPS in maintenance bypass.
Each control board is connected to a control panel with display - by
means of which both UPS status and settings can be checked - and
to a communication interface with an RS-232 connection, SNMP,
free contacts and accessories slot. All UPS functions can be ac-
cessed from any control panel and it is also possible to communicate
through any interface installed: thus even these peripheral devices
are redundant. In UPS installations where there are three separate
single-phase lines in output, each line can be separately software
controlled to privilege, for example, the autonomy of one of them
when running on battery and install only the necessary number of
modules on each phase to have the power required. An input bypass
line separate from the mains input line will allow the bypass to be
powered by a second power source (the neutral conductors of both
lines must be in common). Cutting edge technology is used for the
UPS hardware. The single-phase modules are carefully engineered
and have no power wiring. A sophisticated microprocessor control
optimises UPS performance both on the Booster/PFC side and
on the output inverter. The battery charge curve has been studied
to obtain maximum useful accumulator life and greater autonomy
when there is no mains power.
The electronic boards are entirely assembled on automated Meta-
System lines and tested to ensure the highest possible quality
standards. Each piece of equipment is tested by letting it work for
a long time at full load (burn-in) before being packed and shipped
to the customer. All these measures contribute to the value of the
ARCHIMOD
