PureWave® UPS Systems provides the high-quality, uninterruptible power that data centers need.
For Tier IV 2N systems, S&C’s solution can achieve six 9s availability for your mission-critical facility. PureWave UPS System — available in medium-voltage ratings from 4.16 kV to 25 kV — provides facility-wide backup power for any specified length of time.
The Proven, Most Cost-Effective UPS Solution
The PureWave UPS System is a self-contained, modular, uninterruptible power supply system that can be applied indoors or outdoors. It utilizes maintenance-free batteries.
Featuring field-hardened power electronics technology, the PureWave UPS System provides 60 seconds of protection at full load and up to 180 seconds of protection for reduced loads — eliminating 99% of all power quality problems. Additionally, the PureWave UPS System can be applied with a backup generator, assuring seamless service through extended outages.
The PureWave UPS System has been applied around the world to protect mission-critical facilities including:
- Data and call centers
- Hospitals and health care facilities
- Financial operations
- Communications network centers
- Continuous process industries
- Pharmaceutical manufacturers
- Semiconductor fabricators
- Electronics manufacturers
- Other manufacturing facilities
For applications that require battery run times in excess of one minute, S&C offers an extended-run-time version of the system: the PureWave® UPS XT System.

The relatively low efficiency of dual-conversion on-line UPSs, operated at low utilization factors, creates low overall system efficiencies and high power consumption. The power used for cooling these UPSs contributes to total power consumption too.
PureWave UPS System features a fast-acting static switch design that provides higher efficiencies than conventional on-line UPSs. PureWave UPS System includes the patented PureWave Utility Disturbance Monitor. This field-proven system allows the PureWave UPS System to sense utility voltage deviations at the industry’s fastest rate, while meeting the demanding IEC/EN 62040-3 Class 1 rating for “fast transfer” to battery power.
Other Critical Loads Must Be Addressed
The air conditioners and chillers required to maintain optimal temperature in the data center are now considered critical loads. Some process equipment and business services in the facility may be designated critical loads as well. Additional UPS capacity must be dedicated to protecting these loads. For conventional on-line UPSs, this means that additional interior space — a limited resource — must be dedicated to house both the equipment and their battery banks.
But with PureWave UPS System, all the equipment — including the batteries — can be installed outdoors. No valuable interior, air-conditioned floor space is required.
Reducing Total Cost of Ownership
Reducing a data center's total cost of ownership — its TCO — is an increasingly important goal. Some sources estimate TCO to be as much as four to five times equipment purchase cost . . . with the annual cost of electricity consumption fast approaching the cost of the equipment.
The energy-reduction and efficiency-improvement criteria mandated by Leadership in Energy and Environment Design (LEED®) and other organizations are forcing changes to traditional data center design. The PureWave UPS System is especially well suited to these changes.
Its ongoing operating costs are far less than conventional low-voltage UPS systems.
And the medium-voltage design of the PureWave UPS System greatly reduces the cost of distributing power throughout the facility. Far less copper conductor is required, compared to conventional low-voltage UPS designs.
