for adjusting the power of the connected load. Here, the
setpoint is set with a rotary knob on the module as a
percentage with reference to the 100 % power stored as a
setpoint. In this way the power is kept constant even in the
event of voltage fluctuations or a change in load resistance.
voltage ramp, the inrush current is limited by means of phase
control. This is useful above all with loads such as lamps
which have an inrush transient current.

Application
The power controller adjusts the current in the connected load
by means of a solid-state switching device depending on a
setpoint. Changes in the mains voltage or in the load resistance
are thus compensated by the power controller. The setpoint can
be predefined externally as a 0 to 10 V signal or internally by
means of a potentiometer. Depending on the setting of the
potentiometer (t
principle of full-wave control or generalized phase control.
Full-wave control
In this operating mode the output is adjusted to the required
setpoint by changing the on-to-off period. The period duration is
predefined at one second.
Generalized phase control
In this operating mode the output is adjusted to the required
setpoint by changing the current flow angle. In order to observe
the limit values of the conducted interference voltage for
industrial networks, a choke rated at at least 200 mH must be
included in the load circuit.
