General
The inverters can be connected in
parallel so systems with N+1
redundancy can be constructed.
Inverter range TEBEVERT
Parallel connection can be
used for increasing the
power, and thus system
extension on site is possible
for increasing power
demand.
Systems with up to 5 inverters
connected in parallel are
possible.
The use of modern semiconductors
with high switching frequencies
provides compact construction,
low weight and a very high efficiency.

5000 VA
In order to increase the availability of
the system a mechanical by-pass can
be provided. In case of inverter failure
it automatically switches over to the
public mains (fig. 1) with a low changeover
time.
The EUE (static by-pass) is another
component for increasing the system
safety. Using the EUE the loads are
directly switched to the mains in case
of overload or faults in the
inverter (fig. 2 + 3). This switch-over
is made almost without interruption.
All monitoring and control units are
designed to be intrinsically safe
so that an uninterrupted supply of the
connected load is ensured.
Operation mode
Airport Frankfurt/Main, Benning - Power to Communikation
These products have a very good
dynamic range. At load peaks of
0 %-100 % - 0 %, fluctuations and
voltage surges are corrected within a
very short time.
The plug-in inverters are available
with the output power 1000 VA, 1500 VA
(only 24 V), 2500 VA and 5000 VA.
The cabinets can be installed side by
side with rectifier cabinets of similar
design.
