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 5% and draws a pure sinusoidal waveform from the
mains. This also provides UPS input power factor of 0.99.
Advantages
• Saving in the sizing of upfront equipment e.g. emergency
generators, cablings and circuit breakers
• No disturbances to nearby equipment; eliminate perturbation
and outage on upfront electrical equipment, avoiding also any
investigation and 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.

Output Performance
Total Harmonic Distortion (THD)
A distorted output voltage waveform affects the proper
function of the load's equipment. The TLE Series has
very low output voltage THD, even with connected
100% unbalanced or 100% non-linear loads.
More Available Real Power (KW)
• TLE Series with unity output power factor
provides more output KW. Real Power (KW) equals
Apparent Power (k ).
va
• Suitable for modern power supply application with
unit or capacitive power factor (e.g. new servers
generation), crest factor up to 3:1.
Transient Response
Transient response is very fast due to control
algorithms which reduces the need to oversize
the UPS for pulse load applications.
The TLE Series UPS is rated for
unity output PF, but can handle a
whole range of critical load power
factor without UPS derating.
Many IT server computer
loads have power factors of
0.95 lagging to 1.0 unity.
Many non-IT critical loads have power
factors of 0.75 lagging to 0.95 lagging
GE Series TLE UPS can effectively
support and protect both IT and
non-IT critical loads.
