Brief description

Thyristor power switches are used for the contact-free switching of a.c. loads. A typical
application is the switching of resistive-inductive loads at high switching rates, especially
in the industrial sector, such as in the plastics packaging industry, in HVAC engineering
and in the construction of industrial furnaces.
The control and power sections are electrically isolated by optocouplers.
The control signal range is compatible with the logic outputs of JUMO controllers.
The power section operates as a zero-voltage switch, which means that it always switches
when the voltage passes through zero, irrespective of the instant of the signal change.
This prevents the generation of interference voltages. A varistor is integrated on the output
side as a protection against voltage spikes.
The input status is indicated by an LED.

Derating tables

The maximum thermal resistance between the baseplate of the thyristor power switch and the environment R(
function of the load currents and the different ambient temperatures. The matrix below has been provided for this purpose. The power
loss at a given nominal current can also be taken from this matrix.

A

Selected thyristor power switch: TYA 432-45/25, 265
The maximum thermal resistance of the heat sink can be seen from the matrix to be 3.8 °C/W.

Important note:

Use a silicone-based heat transfer compound between the heat sink and the thyristor power switch. If you use a heat transfer compound
that does not contain silicone, then you have to make sure that the chemical silicone substitute does not attack the Noryl SE 1 GFN 1
of the plastic housing. We recommend the use of silicone-based heat transfer compounds, e.g. Dow Corning.
To ensure safe operation at maximum performance, it is essential to strictly observe the thermal requirements according to the derating
tables.
