Frequently Asked Questions
What is a power unit required for?
By means of a power controller, it is possible to supply
well regulated or controlled electric energy (e.g. monitored, non-wearing, with
high efficiency) to a consumer.
Which kind of load can be connected
to an AEG SVS power controller?
- Resistive load
- Resistive load with
large warm / cold resistance ratio
- Transformer load
(transformer with resistive load)
- Capacitive load (Thyro-C only)
Which types of power controller are
available within the Thyro family?
- Single-phase
controlled, for single-phase loads
- Two-phase controlled,
for two-phase loads (so-called saver circuit)
- Three-phase
controlled, for three-phase loads
- Type current 8 A to
2900 A
- Type voltage 230 V to
690 V
- Type power 1,8 KW to
2.8 MW
What is the difference between a thyristor switch and a thyristor
power controller?
Thyristor switch
Depending on the control signal, the load is fully switched to the line voltage
or idle. In connection with a temperature controller, the thyristor
switch can be used, e.g., for two-position actions.
Thyristor power controller
Proportionally to the control signal, the load is variably
supplied with energy. Depending on control mode and power unit, it is possible
to implement U-control, U²-control, I-control,
I²-control or P-control.
Which control modes are available?
- U-control
- U²-control
- I-control
- I²-control
- P-control
Which operating modes are available?
- VAR = Phase angle control
(according to the set point, each half-wave of the line voltage is more or
less connected through to the load).
- TAKT =
Full-oscillation cycle mode operation (within a TAKT period, the load is
switched on / off once).
- QTM = Quick Takt Mode is a fast variant of the TAKT mode and
particularly suitable for infrared radiators.
- SSSD =
Soft-Start-Soft-Down (like TAKT, however, with Soft-Start-Soft-Down ramp
in the phase angle control).
- MOSI = Sub-mode of
TAKT or VAR for peak current limitation during the heating-up phase of
temperature-dependent load resistors.
Which types of monitoring are
possible?
- Device monitoring
- Load monitoring (also
partial load)
- Line voltage
monitoring
Which synchronization procedures are
available?
Synchronization procedures can be
used for applications with several power controllers. They serve to minimize
the mains loading and thus to minimize investment and operating costs. They
simultaneously minimize mains feedback.
How to select the most suitable
power controller?
- The required load
power and the available voltage determine the type power of the actuator.
- The kind of load
(resistive load, transformer load) determines, together with the
requirements on the dynamic accuracy, the type series and the number of
phases to be controlled.
- In case of loads /
applications which can be operated in the TAKT mode, a thyristor
power unit with saver circuit (2 controlled phases: => smaller,
lighter, less power loss, more cost-saving) can be used.
