The purchase price of a conventional UPS is generally 10-15 percent less than that of an advanced modular system. However, the purchase
price is not the only decisive factor if the overall costs are considered.
A conventional UPS involves higher operating costs than a system based on modular technology, which is also able to reduce the cost
for wasted energy. In the long-term, cost comparison tips the scales in favour of modular technology because, even though the purchase
price is higher, it is already paid back during the  rst years of use.
RANSPORTATION COSTS
A conventional UPS generally includes an output transformer, which makes the device two or three times heavier than a new generation
UPS. This means that transport costs over 50 percent more. A UPS formed by modules can be easily transported and installed without
requiring any special vehicles.

INSTALLATION AND POWER (IN kVA) COSTS PER FOOTPRINT
The conventional UPS needs an area (calculated in m²) that’s two or three times larger than an advanced modular system like TRIMOD.

RELIABILITY (REDUNDANCY, AVAILABILITY)
The reliability of a system depends on the mean time between failures (MTBF) and the mean time required to repair (MTTR).
MTBF represents the reliability rate of the system and its components and is expressed in mean operating hours between two faults.
MTTR represents the restoring rate of the system and its components and is expressed in mean operating hours required to restore the
system.
Power module redundancy increases the MTBF.
A UPS with modular-redundant architecture can be con gured as a power redundant N+X system so that zero downtime is guaranteed even
if a module fails.
Complete diagnostics and modular architecture reduce the MTTR.
Precise indications and a large displais allow faults to be immediately identi ed.
Modular architecture allows the device to be repaired very quickly by simply replacing the faulty module without a downtime and with a very
high restoring rate at the very  rst intervention.
