1.3 Type designation

The type designation of the Thyristor Power Controllers is derived from the construc-
tion of its power section:
Thyro-A 1A Thyristor controller with single phase power section
suited for single phase loads
Thyro-A 2A Thyristor controller with double phase power section
suited for symmetrical loads in three phase operation in
three phase saver circuit
Thyro-A 1A Thyristor controller with single phase power section
The complete type range can be found in chapter 9, TYPE OVERVIEW.
2. Functions
To enable Thyro-A to adjust optimally to the desired application, it is equipped with
a wide range of functions. These are described below. Further functions are possible
by applying Thyro-A within a bus system. See also chapter 5 INTERFACES.

2.1 Operating modes

For optimum adjustment to different applications and production processes, as well
as different electrical loads, the most favourable operating mode can be set.
Full wave switch TAKT (for 1A, 2A)
Depending on the prescribed set point, the mains voltage is periodically switched. In
this operating mode almost no harmonics are created. Whole multiples of the mains
periods are switched, thus avoiding d.c. components. The full wave switch mode is
especially suited for loads with thermal inertia. Depending on the function angle 1.
half wave, the phase frequency is adjusted independently to 5 or 50 mains
periods = T
with 400 Volt type voltage
with 280 Ampere type current
with integrated semi-conductor fuse
with ventilator (only 280 Ampere types)
with indication relay
with load monitoring
P with additional power control
1 designation Thyro-A, 2002 series
