>Better power factor
The power factor the TRANSOTRONIC range reaches
0. (fig. 1).
Harmonic distortions produced the switching character
istic the thyristors and can cause disturbances other

Furthermore, the mains will loaded with apparent

These plants require, reliable power supply independent of
the public net, which most often achieved using battery-
secured power supply. ]
In larger plants, devices with 220 and current outputs
of several hundred amps are often used.
However, one the disadvantages these devices the
level harmonic distortion fed back the mains.
• Simple battery capacity testing mains feed back
without the use external load
. The output voltage change
with load steps from 100 and from 100 %
is only approx.

• Good dynamic behaviour
Even when not connected battery, the TRANSOTRONIC
has good dynamic behaviour. The TRANSOTRONIC with sinusoidal input power ensures
distortion free rectifier operation

Better performance because IGBT technology
