8.4.2 DC-supply power
The parameters relevant for the selection of a supply unit with a suitable supply power
(even in the overload range) are listed in the below table:
U
Lr
Rated AC voltage
Cycle 1 Cycle for the second-range
Cycle 2 Cycle for the minute-range
P
DC 100%
Permanent power of DC-voltage level
P
ol
Power supply during overload time
t
ol
Overload time
P
re
Power supply during unloading time
t
re
Relief time
Any other cycles are calculated with the following formula:
(P
ol
⋅ t
ol
) + (P
re
⋅ t
re
)
t
ol
+ t
re
≤ P
DC 100%
Cycles other than the above cycles must not exceed the specified power and time values,
i.e. the values must be used as maximum values.
The values depend on the rated AC voltage U
Lr
