We can provide UPS Systems 10kVA and larger in 3-phase models. One of the most popular and most efficient models available is the American Power Conversion (APC) Silcon® series UPS.
APC delivers the new wave of 3-phase power protection
What makes a hot technology “hot”? In the eyes of an enterprise customer, “hot” means a technology that’s convenient and easy to use, and efficient and trouble-free to operate. A “hot” product is manufactured of high quality materials and as a result of its superior design, inherently carries a low cost of ownership. All of these characteristics define APC’s Silcon® Series Delta Conversion On-line™ machines. The unique architecture of the APC Silcon Series introduces a new category of power protection: the highly efficient 3-phase UPS. Customers who install APC Silcon Series systems immediately begin to realize benefits in the form of dramatic reductions in energy consumption costs, installation and wiring costs, air conditioning costs, harmonic distortion costs and maintenance costs. More importantly, the APC Silcon Series units excel at their primary function: to supply clean 3-phase power to critical applications, datacenters and facilities regardless of power failures, sags, surges, brownouts, line noise, high voltage spikes, frequency variations and switching transients.
Features and Benefits
Availability
Customers can now enjoy the benefits of redundant UPSs by configuring and installing
multiple 20kVA units. For example, if kVA requirements are high, up to 9 500kVA UPSs can
be paralleled to supply the load with the energy it needs. Up to four units can be
configured in parallel mode without requiring the installation of expensive external
static switches.
Advanced power management
Silcon’s intelligent control can be programmed to maximize the overall
efficiency of parallel Delta Conversion On-line systems. By designating as
“active” only the systems needed to supply the load, the other systems can be
held in “stand by” mode, ready to start up without interruption when required.
Furthermore, to reduce stress and improve reliability, the load can be switched between
the parallel systems in preprogrammed sequences.
Lower cost of ownership
The Silcon Series is higher in efficiency that other online technologies. The Delta
Conversion On-line units simply do not consume large quantities of energy and also produce
much less heat. Customers need not oversize an air conditioning unit to compensate for the
heat loss which traditional UPSs generate.

Lower installation cost
The Silcon Delta Conversion On-line UPS has a power factor corrected input, ensuring that
the input power factor is always one, regardless of load and utility voltage. A power
factor of one minimizes installation costs by requiring smaller cables and smaller fuses.
Eliminates wear and tear on electrical infrastructure
Utilities and power distributors are creating standards to limit the harmonic distortion
produced by users. Violating these standards can be very costly. Many double conversion
3-phase systems produce a level of harmonic distortion high enough to negatively impact
the utility and its customers. To remedy the situation, customer are obliged to install
large expensive filters. These filters further diminish the overall efficiency of the
double conversion machine. The Silcon Delta Conversion On-line technology, which maintains
a sinusoidal utility current, eliminates this 3-phase double conversion topology problem.

Compliant with power supplies, for the present and the future (kVA = kW)
Over the past three years, more and more computer manufacturers have built Power Factor
Corrected (PFC) power supplies into their servers. In order to avoid unnecessary wear and
tear on computer components, the Volt-Amps (VA) requirements of all the computers that
make up the load need to equal the Watts (W) capacity of the UPS. The Silcon Series units
are PFC compliant. Without derating the unit, double conversion 3-phase UPS systems are
not PFC compliant. Therefore, as more and more PFC computers enter into your datacenter,
the probability becomes greater that the legacy double conversion 3-phase UPSs becomes
overloaded. With Silcon Series units, this problem is eliminated because the kVA rating of
the Silcon Series unit equals the kW rating.
Many sizes and run-times to choose from
Select from the following lists of standard ratings. And multiple units can be paralleled for even greater flexibility.
