For 6EP3437-8UB00-0AY0 (24 V/40 A)
Switch

A
influences the output
characteristic in the
load range
Parallel operation:
"Soft" characteristic curve (see
Figure 6-20 Output
characteristic 6EP3437-8UB00-0AY0 parallel opera-
tion (B OFF) (Page 67)) for the parallel operation of
two or more devices: The output voltage falls with
increasing output current.
This means that for full output current the highest
output voltage can normally no longer be attained.
Single operation:
delivery condition
"Hard" characteristic curve (see Figure 6-
11 Output characteristic 6EP3437-
8UB00-0AY0 single operation (B OFF)
(Page 64
)) for normal operation (single
operation): The output voltage is inde-
pendent of the output current.
B
is used to switch over
the output current
Rated current:
I
out rated
= 30 A, no latching shutdown
