Description
Mains voltage limit value
above which the power re-
duction takes place.
Gradient by which the ef-
fective power is reduced.
Example - conversion from
static to gradient:
Static s = 4 % → Gradient k
= 1/(0.04*230 V) =
10.9 %/V
= Indicates the reference
power for calculating the
(k*dV)

power limit in the event of
overvoltage or under-
=
voltage.

Reference power:

mains voltage limit
value is exceeded.
- P → Nominal power
n
of the device.
Deactivates extended act-
ive mains support for
devices with battery.
Activates extended active
mains support for devices
with battery.
Mains voltage limit value
above which the power in-
crease takes place.
Gradient by which the ef-
fective power increases.
Example - conversion from
static to gradient:
Static s = 4 % → Gradient k
= 1/(0.04*230 V) =
10.9 %/V
