OPERATING
PRINCIPLE
Electronic analog regulators of single-phase AC voltage, which use the phase-cutting principle (Triac) in order to vary the
output active voltage applied to a resistive or inductive load.

OPERATING
CHARACTERISTICS
Master (Controller Mode)
(inputs IN1,IN2,IN3)
The output voltage varies in order to maintain the value measured by the
transducer within the proportional band (Pb = factory calibration)
Slave (Power Unit Mode)
(Input IN4)
The output voltage varies according to the 0-10 Vdc control signal applied to the
input IN4, according to the current configuration.
