S5K Modular Series Uninterruptible Power Systems (UPS)

This easily upgradeable and flexible UPS provides the protection you want, when you need it.

The 5K Modular is scalable from 4 to 20 KVA, offering many flexible options by adding a few standard modules. Designed to be fully configured, tested and shipped in the configuration you need, the 5K Modular also has the ability to be easily upgraded in the field to either higher VA ratings (up to 20 KVA maximum), longer runtimes or to add N+x parallel redundancy. Configurations can be cost-effectively upgraded keeping your 5K Modular current without a large reinvestment in a new system.

The optional N+x redundancy provides a fault-tolerant group of power modules and controls. The modular design is easy to upgrade so the UPS can grow with the needs of the system that is being protected.

Each of the modular components, including 4 KVA power modules, battery modules and system control modules, can be hot-swapped making it easy to increase power, extend your backup runtime or add redundancy while still providing power protection to the load.


This fault-tolerant system uses intelligent power and battery modules which take themselves off-line if there is a problem — without interrupting power to the load. Self-diagnostic capabilities simplify maintenance and troubleshooting. Each unit incorporates an internal automatic bypass.

Applications Top
  • Network servers
  • Enterprise telecommunications systems
  • Clusters of PCs or workstations and peripherals
  • LAN gateways, bridges and routers
  • Mini-computers, superservers and server clusters
  • RAID arrays and other large-scale data handling system
Features   Top
  • Scalable for capacity, redundancy, or battery run time offering unbelievable flexibility
  • Built-in intelligence is provided for each individual module using microprocessor controls, increasing functionality, communications and reliability
  • N+x parallel redundancy is easily achieved by adding extra control, power and battery modules
  • Any failed module will automatically take itself off-line while the other modules continue to
    support the connected equipment
  • Multiple and simultaneous communication ports
  • Variable input voltage range minimizes battery operation to increase battery life
  • An automatic internal bypass for maximum availability of output power
  • Continuous sinewave output
  • Power factor corrected input reduces reflected distortion and optimizes utility power
  • Two-year limited warranty (Includes factory start up)
Chassis Options Top

The S5K Modular has two chassis available to build on. 

  • The "A" chassis can accommodate up to 8 modules
  • The "B" chassis can accommodate up to 12 modules and supplies 16 KVA of power with N+1 redundancy
  • The "C" chassis can accommodate up to 12 modules and supplies a full 20 KVA of power with N+1 redundancy

System control modules are not included in module count. All chassis can accommodate up to two system control modules. Select the proper chassis based on your futures need for expansion or redundancy. In most standard (non-redundant) applications, the “A” chassis is the most popular.  

Selection Steps Top
  1. Determine the maximum KVA you will need for future expansion.
  2. Determine the KVA and run time value for your immediate need.
  3. Determine if you need redundancy. If the exact run time is the critical need, use the fully redundant option (see Selection Charts).
  4. Select the unit that meets both your immediate requirements, and is expandable to your future needs in the "Maximum Upgrade" column in the selection table. The Maximum Upgrade column shows the highest KVA expansion that particular configuration is capable of without removing any of the battery modules from the original configuration.
