Thyristorised AC power controller is used for
electrically heated furnace as a replacement of conventional
ON/OFF control by AC contactor. Precise temperature control
is achieved through PID temperature controller interface.
Salient Features:
Precise and accurate temperature control with regulation of
+/-1%
Back to back thyristor connection.
Integral cycle control with variable time base.
Two-leg control is adequate for three phase system, since un-controlled
phase is regulated automatically.
Device protection is with high speed over current trip circuit.
Optional over temperature trip by an ON/OFF temperature controller
