5 Configuration
Operating mode
(Is displayed in the
measured value lev-
el in the info line) Burst-firing
mode - For slow control loops
- For free-running economy circuit
- Low EMC interference through zero-voltage switching
- No reactive power is generated
Phase angle
control mode - For fast control loops,
such as lighting controls
- No flickering
Half-wave control Note:
Subordinate control loop cannot be set!
The half-wave control operating mode is only possible in sin-
gle-phase power controller operation. It is a special type of
phase angle control mode used, for example, for vibrating
magnets. In half-wave control, one SCR branch remains per-
manently locked so that only the positive half-wave is allowed
to pass through.
The specified setpoint value is converted to a phase control
angle of 180 °el. to 0 °el.
In this operating mode, it is not possible to measure either
load voltage or load current, which makes a subordinate con-
trol loop impossible.
