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 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 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.
Unity Output Power Factor
• TLE Series with unity output power factor provides more
real power. kVA equals KW – no derating with any load,
see Power Capability diagram below.
• 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 ensure very high dynamic stiffness. This reduces the
need to oversize the UPS for pulse load applications.
Unity output power factor, full power for critical load
without derating for actual and future IT loads.
