Key Features

Run time for load W
Run time for load
Enter the total load (power draw) of all devices to be protected by the UPS here. Based on the value entered we will estimate the run time that you will have during a total power outage. Adding run time increases availability by allowing the system to operate through longer outages without shutting down.

The total load (power draw) entered exceeds the maximum value for this product (480000W)

Silcon Features & Benefits

Total cost of Ownership

Fully-rated power kVA equals kW
Reduces cost by eliminating the need for an oversized UPS for Power Factor Corrected (PFC) loads.
Temperature-compensated battery charging
Prolongs battery life by regulating the charge voltage according to battery temperature.
Input Power Factor Correction
Minimizes installation costs by enabling the use of smaller generators and cabling.


Automatic internal bypass
Supplies utility power to the connected loads in the event of a UPS power overload or fault.
200% overload capability
The APC Silcon Series has the ability to supply 200% overload in normal operation for a period of 60 seconds. This enables the system to handle inrush currents, sudden peak loads and output faults without transitioning to bypass. The result is increased availability.
Parallel-capacity capable
Increases total power capacity by using multiple uninterruptible power supplies simultaneously.
Parallel-redundant capable
Power the connected equipment with multiple uninterruptible power supplies to increase system redundancy
Generator compatible
Ensures clean, uninterrupted power to protected equipment when generator power is used.
Intelligent battery management
Maximizes battery performance, life, and reliability through intelligent, precision charging.


Customize UPS capabilities with management cards.
Network manageable
Provides remote power management of the UPS over the network.
Audible alarms
Provides notification of changing utility power and UPS conditions.
Manageable external batteries
Reduces preventative maintenance service needs by monitoring the health and status of the external batteries and their expected runtime.
LCD display
Alpha-Numeric Display which displays system parameters and alarms.

Marketing features

Input Power Factor Correction
Eliminates the need for an external phase-compensation unit and minimizes installation costs by enabling the use of smaller generators and cabling.


Locking cabinet
Prevents unauthorized access to the UPS.
Safety-agency approved
Ensures the product has been tested and approved to work safely with the connected service provider equipment and within the specified environment.
Automatic self-test
Periodic battery self-test ensures early detection of a battery that needs to be replaced.
