Parameter Range of val-
ues Description Availability
"Activation
Threshold Over-
voltage" 208
‑
311 [V] Mains voltage limit value
above which the power re-
duction takes place.
"Gradient Over-
voltage" 0.01
‑
100 [%/
V]
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
power limit in the event of
overvoltage or under-
voltage.
Reference power:
- P
m
→ Momentary
power when the
mains voltage limit
value is exceeded.
- P
n
→ Nominal power
of the device.
"Active Grid

ive mains support for
devices with battery.

On Activates extended active
mains support for devices
with battery.
"Activation
Threshold Un-
dervoltage" 0
‑
311 [V] Mains voltage limit value
above which the power in-
crease takes place.
"Gradient Un-
dervoltage" 0
‑
100 [%/V] 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
