Product Description
The transformer soft starter
TSE6-1 is an electronic relay
with a new integrated soft
start procedure which
switches on single phase
transformers without inrush
current. It can either be
transformer with EI-cut strip-
wound core or toroidal core
with any secondary load or it
can be a parallel connection
of different types of trans-
formers. The soft start pro-
cedure used is patented and
works with the premagnet-
isation of the transformer.
The TSE6-1 is available in
three different versions: As
compact version up to 16 A
with internal thyristor and
bypass relay or as control
unit in combination with ex-
ternal thyristors or semicon-
ductor relay with bypass
contactor for high currents
(> 16 A).

General Specifications
Mode of Operation
The TSE6-1 is used for soft-
starting of 1-phase trans-
formers. The factory is deli-
vering the TSE6-1 calibrated
for transformers with EI, MI-,
resp. UI-cores. The adap-
tation for other transformer ty-
pes is possible by adjusting
the build-in selector. The
TSE6-1 can be controlled eit-
her with a direct voltage, com-
parable to a solid state relay
or in another version with a
volt-free contact. The signal
output (Hi, Lo) is conductive
as soon as the TSE6-1 has
fully switched on after the
premagnetisation of the trans-
former. A green LED is indica-
ting the status of the signal
output. With the bypass relay
resp. contactor the control
unit is short-circuited directly
after switching on to avoid
energy loss. When using thyri-
stors or semiconductor relays
with heatsink the bypass relay
resp. contactor is not needed.
The TSE6-1 recognizes itself
whether a bypass contactor is
connected or not.
The TSE6-1 controls the main
voltage and turns off if the vol-
tage limiting values are exceed-
ed. The red LED blinks with a
frequency of 1 Hz in case of
undervoltage and with 4 Hz
frequency in case of overvol-
tage. If there is an internal fault
the red LED is continuously
on.
An internal jumper (J1) is cali-
brating whether the TSE6-1 is
switching on itself after a fault
(default position) or if it has to
be returned by taking away
the mains voltage or the re-
mote-On signal.
As an option the TSE6-1 has
the possibility of reacting to
mains voltage deformations
(loop failures, short power fai-
lures) which cause saturation
current in the transformer, re-
leasing the fuse of the trans-
former by turning off the
TSE6-1 and the transformer
before the saturation currents
occur and then directly swit-
ching on again the transfor-
mer with the standard soft-
start procedure.

Wiring Diagram
A main switch is not required when using the remote-
On input for switching on/off.
F1, F2 are fast fuses for operational current or circuit
breakers with B characteristic.
F2 can be eliminated when TSE6-1 is connected to L1
and N.

Caution:
The TSE6-1 contains thyristors. When TSE6-1
is turned off there is no galvanic separation
between transformer and mains supply.
Jumper J1
(inside, on PCB)
When jumper J1 is closed,
TSE6-1 switches ON auto-
matically after a fault (high-/
low-voltage, technical fault).
When jumper J1 is open,
TSE6-1 switches ON only
when remote-ON resp. mains
is switched OFF and ON
again.
Default setting: jumper J1
closed.
Jumper J2
(inside, on PCB)
When jumper J2 is closed,
TSE6-1 switches ON without
remote-ON signal. When
jumper J2 is open, TSE6-1
switches ON only when re-
mote-ON signal is ON.
The size of pre-magnetisation of the transformer can be ad-
justed by the tuning knob
named transformer selection.

External Thyristor-Modules RTH .
When current > 16 A the
TSE6-1 must be used in
combination with one of the
three thyristor modules
RTH1, RTH2 or RTH3. In
these thyristor modules
gate-cathode diodes (e.g.
1N4007), gate-cathode-re-
sistor and the RC-part (47
/
150 nF) are already integrat-
ed. For this reason these
thyristor modules can be
connected to the TSE6-1
without any restrictions.
Correctly dimensioned heat-
sinks are already integrated
in the thyristor-modules.
