Change-over switch

Selector switch (example 6EP1456-3BA00 / 6EP1437-3BA20)
The two switches A and B are used to influence the output characteristic curve:
Switch
ON
OFF
A
influences the output
characteristic
in the load range
Parallel operation:
'Soft' characteristic curve (see, e.g. Figure 6-8
6EP1436-3BA10 parallel operation output char-
acteristic curve (Page 46)) for the parallel oper-
ation of two or more devices: The output
voltage falls with increasing output current
(namely, also for the overcurrent pulse!).
This means that for full output current the high-
est output voltage can normally no longer be
attained.
Single operation:
Delivery state
'Hard' characteristic curve (see, e.g. Figure 6-3
6EP1436-3BA10 single operation output char-
acteristic curve (Page 44)) for normal operation
(single operation): The output voltage is inde-
pendent of the output current.
B
influences the output
characteristic
in the overload range
Latching shutdown:
If the output current rises above the rated value
and above the current limit, the device reduces
the output voltage (see, e.g. Figure 6-13
6EP1436-3BA10 latching shutdown output
characteristic curve (Page 48)). If the output
voltage falls below (10 V), (20 V), (40 V), the
device shuts down latching, the red LED lights.
This limit voltage of (10 V), (20 V), (40 V) is
independent of the set output voltage. The
'Short-time overload current' feature is not
available in this operating mode. In order to
also be able to charge large capacitances in
this operating mode at the output, non-latching
shutdown is performed during the first ten sec-
onds after power on. During these first 10 s, the
device responds for overload as if the switch is
OFF.
Constant current:
Delivery state
If the output current rises above the rated value
and above the current limit, the device reduces
the output voltage. The yellow LED lights if the
output voltage falls below
(10 V), (20 V), (40 V).
Delivery state: A-OFF; B-OFF
