power quality productPureWave® UPS Systems
S&C’s PureWave UPS System protects power-sensitive equipment from the detrimental effects of disturbances such as voltage sags, surges, transients, momentary disruptions, and complete outages. This unique Smart Grid solution supports the entire load with clean power for up to 60 seconds, eliminating 99% of all power quality problems. It supports reduced loads for up to 180 seconds. A high-efficiency static switch provides immediate — 2- to 4-millisecond — response. We now also offer an extended run-time version of our UPS, the PureWave® UPS-XT.  This product provides S&C’s field-proven UPS technology applied to projects that require battery run-times in excess of one minute.


The PureWave UPS System can be seamlessly coordinated with a backup generator set. Ride-through time can be tailored to permit start-up, then “soft” load transfer to the backup generator, for 100% protection through extended outages. No costly utility paralleling switchgear is needed. And the backup generator can be sized up to 35% smaller than with conventional UPS systems.


  • More than 98% energy-efficient — highest in the industry.
  • Reduced carbon footprint
  • Static switch design
  • When selecting a medium voltage PureWave UPS, the copper conductor costs of distributing power are greatly reduced when compared to conventional low-voltage desgins.

Installable Outdoor

  • No need to construct a building or an addition to house the equipment. The PureWave UPS System is completely self-contained in a NEMA 3R (IP 14) enclosure, with an exceptionally small footprint.
  • Reduces interior air-conditioning load, resulting in increased savings.

Scalable, Low- and Medium-Voltage Models

The PureWave UPS System is available in a wide range of capacities. It can provide power protection for an entire facility.

Just purchase the capacity required for your present critical load. Additional 313-kVA modules can be added at any time, as the critical load grows. As many as eight 2.5-MVA containers can be paralleled to protect medium-voltage loads up to 20 MVA.

  • Low-voltage models. Available in capacities from 313 kVA up to 2500 kVA for 208- to 600-volt applications.
  • Medium-voltage models. Available in capacities from 2.5 MVA to 20 MVA for 5- to 28-kV applications.

Unmatched Features

  • Truly maintenance-free batteries with non-prorated 5-year warranty. Batteries can be 100% recycled.
  • Quiet operation. Audible noise is less than 55 dB(A), compared to 72 dB(A) for conventional UPS systems.
  • The field-proven PureWave utility disturbance monitor is a patented detection system that allows the PureWave UPS to sense utility voltage deviations at the industry’s fastest rate while meeting the demanding IEC Class 1 rating for “fast transfer” to battery power.
