V1.04/EN/00561071 [Thyristor Power Switch TYA 201] 43
3 Electrical connection
Advantages The free-running economy circuit has the advantage that, on average, the sup-
ply voltage is subject to less impact stresses (asynchronous switching).
Both power controllers operate independently of each other and control the
required 3-phase power precisely.
Even a possible partial load failure will not necessarily have an effect on the
temperature stability of the control loop.
709061/X-XX-XXX-001-XXX-XX-XXX (code 001) is required in the order code
for both power controllers.
3.4.6 Master-slave 3-phase current economy circuit for resistive loads in star/
delta connections, or transformer loads (resistive-inductive)
Important infor-
mation: The master-slave 3-phase current economy circuit is achieved with version
TYA 202 type 709062.
The control electronics of the master power controller assume the actual pow-
er control function, and drive the slave power controller in synchronization.
This makes it possible to operate transformer loads.
