Thyristor power switches

with integrated cooling body
to be snapped on a DIN rail or for screw connection

Brief description

Thyristor power switches are required for contactless switching of alternating current consum­ers. Typical applications include the switching of ohmic inductive consumers subject to a large
number of duty cycles, in particular encountered in industry, such as, for instance, plastic pack­aging industry, air conditioning and heat engineering as well as heat treatment plants.
The control and power sections are electrically isolated by optocouplers.
The control signal section is compatible with the JUMO controller logic outputs.
The power section functions as a zero voltage switch, i.e. independent of the point in time when
the control signal changes, switching always takes place at zero voltage.
In this manner power failures are reduced.
The input status is indicated by an LED.
