SMR-D SERIES Mono Phase 1 kVA - 50 kVA Servo Stabilizer


SMR-D Series Mono Phase Servo Stabilizer regulates the mains voltage as fully automatic. It has been manufactured with the capacity to operate smoothly even when the voltage fluctuates at full load. The servo system within Servo Voltage Regulators provides the control of the DC motor with thyristor. Thanks to the booster transformer and variac (auto transformer) , voltage regulation is made at the output.
