The control and monitoring concept the
TRANSOTRONIC series incorporates the following
important functions:____________________________
Soft start without Inrush current
When restarting the rectifier after power failure the starting
current the transformer limited the rated current and
inrush current avoided.s

Output characteristic
The output characteristic the TRANSOTRONIC rectifier is
an curve (according DIN 41773) for standby parallel
operation with NiCd lead acid batteries (fig. With this test, a
constant current discharge the battery with mains back
feed carried out i.
Battery-circuit test
The TRANSOTRONIC includes the important function an
automatic battery circuit test. The test stopped automatically deep
discharge voltage 1. the
battery does not supply this current, battery error message
with common alarm indicated.e. The discharge
current preset and generally the rectifier rated
current (range adjustment 100 %).8 V/c (adjustable). decreasing the TRANSOTRONIC
output voltage small current taken out the battery. 3).
The TRANSOTRONIC reduces its output voltage that the
connected load supplied the battery. the load current is
smaller than the desired discharge current, the TRANSOTRONIC
makes the difference backfeeding the battery energy
into the mains. the discharged energy fed back into
the three-phase mains.
Automatic charging
The TRANSOTRONIC controller operates automatically. The battery capacity test can take
place with without load connected. The
change-over from boost float and vise versa occurs auto
matically dependent the battery voltage and current, thus
enabling faster recharge.
Battery capacity test
The battery capacity test started manually. The equalizing charge facility is
operated manually. For initial
charging equalize charging, the output characteristic can
be switched characteristic. the error acknowledged,
by operation the RESET key further test will carried out
as recheck.
