5 Configuration
Current limiting
No
No current limiting
Yes
Current limiting is implemented via phase-angle control. In this
case, the load current is monitored on the basis of the select-
ed current limit value and only the phase control angles that
do not cause the current limit value to be exceeded are per-
mitted.
If burst-firing operation is active, current limiting only operates
during the soft start that is realized via time-limited phase an-
gle control.
It is also possible to activate an external current limit value
via a digital input.

Chapter 5.1.6 "Digital inputs"
Current limit value
10 % to max. load
current +10 % of the
device type
Varies depending on the device type.
For 20 A power controllers, 2 to 22 A can be selected.
v
Resistance limita-
tion
Note:
Resistance limitation is only possible in the case
of power
controllers with integrated subordinate control loop P (code
001 in the
order code
).
No
No limitation through load resistance
Yes
The load resistance is monitored to ensure the selected resis-
tance limit value is not exceeded if the load current is > 5% of
the power controller's nominal current.
For phase-angle control, limitation is implemented through the
phase control angle
α
.
For burst-firing operation, limitation is implemented through
the ON/OFF ratio of the sine waves.

Chapter 6.6 "Resistance limitation (r-control)"
Resistance limit
value
0 to 999.99
Ω
If the load resistance exceeds this value, it is limited by phase-
angle control or limitation of the switched sine waves.
Load type resis-
tance limitation
Note:
This parameter only appears in the phase-angle control oper-
ating mode.
Resistive load
This setting is to be used for purely resistive loads.
Transformer load
This setting is only to be used for a resistive load via a trans-
former.
Dual energy man-
agement
Switched off
This parameter only appears with the following settings:
Cycle time: fixed (500 ms),
Operating mode: burst-firing operation.
This setting allows 2 devices to be configured so that they do
not simultaneously draw power from the mains voltage at
small output levels.
This prevents current peaks.
