GE Industrial Solutions - Uninterruptible Power Supplies

Uninterruptible Power Supplies - TLE Series™ - Redundant Parallel Architecture - RPA

Energy Efficiency

GE’s TLE Series™ UPS is one of the most energy efficient double-conversion UPS in the industry and provides world-class energy efficiency across the operating load range. The TLE Series™ delivers efficiency up to 96.5% in double conversion mode and 99% in eBoost operating mode. This system efficiency substantially reduces operating and cooling costs, thus providing a reduced cost of ownership and improved power usage effectiveness (PUE) compared to conventional UPS.

GE’s UPS performance is optimized at 50-75% load operation, as this is the most common operating range. The optimization of the TLE Series includes selecting all major power chain components based on maximising the component efficiency at part load conditions.

High Efficiency TLE Series™ UPS Provides:

  • Substantial reduction in operating cost of UPS
  • Reduced energy loss minimizes air conditioning requirement
  • Energy savings from reduced cooling

RPA (Redundant Parallel Architecture)

Input Performance

Clean Input Performance
The TLE Series IGBT based rectifier and innovative control algorithm ensures an input Total Harmonic Distortion (THDi) of less than 3% and draws a pure sinusoidal waveform from the mains. This also provides a UPS input power factor of 0.99.

Advantages

  • Saving in the sizing of upfront equipment e.g. emergency generators, cabling & circuit breakers
  • No disturbances to nearby equipment; eliminate perturbation & outage on upfront electrical equipment, avoiding also any investigation & analysis cost due to malfunction

Programmable Soft Start
The programmable soft start allows the rectifier to ramp up in a programmable time period (0-15 seconds), thus eliminating in-rush current. This feature reduces the need of oversizing the input power system (gensets, feeder cables and overcurrent devices).

Generator Compatibility
User-programmable features such as slew rate, phase angle rate-of-change and voltage rate-of-change allow the UPS to quickly sync to a genset during emergency back-up.

Unity output power factor, full power for critical load without de-rating for actual and future IT loads.

TLE Series Power Capability

Unity output power factor, full power for critical load without de-rating for actual and future IT loads.

Output Performance

Total Harmonic Distortion (THD)
A distorted output voltage waveform can affect the proper function of equipment. The TLE Series™ has very low output voltage THD, even when connected to 100% unbalanced or non-linear loads.

Output Power Factor = 1

  • TLE Series with unity output power factor provides more output power. Output power factor diagram symmetrical with respect to zero. 100% kW – no de-rating with any load
  • Suitable for modern power supply applications with unity or capacitive power factor (e.g. new generation servers), or up to 3:1 crest factor loads

Transient Response
Transient response is very fast due to control algorithms which ensure very high dynamic stiffness. This reduces the need to oversize the UPS for pulse load applications.
