Convenience in Power Management Ensuring Seamless Growth... STATIC VOLTAGE REGULATOR Static Voltage Regulator is a Thyristorcontrolled microprocessor-based electronic device, having an Isolation Transformer & RFI/EMI filters. It regulates fluctuating voltages in a precise manner & constitutes a high-level spike suppression system which protects the equipment by virtually eliminating any transients in the distribution network. Static Voltage Regulator is most suitable for 24-hour continuous process operations where break downs due to fluctuations results in heavy financial losses and damage of expensive equipments. APPLICATIONS TECHNOLOGY SVR regulates the voltage through the tapping selection by means of semi-conductor static switching devices viz. Thyristors, IGBTs which respond instantaneously. In addition, microprocessor-based control circuitry along with Thyristors results in high correction speed and higher efficiency. There is no moving part inside SVR and it is a fully electronic & automatic unit. ! Refineries & their distribution outlets ! Hospitals, Diagnostic Iabs & Imaging equipments !

UPS bypass & Power distribution COMPARISON BETWEEN STATIC VOLTAGE REGULATOR & SERVO VOLTAGE STABILIZER Static Voltage Regulator Servo Voltage Stabilizer Output voltage is regulated by using multi-tapping transformer or Buck Boost transformer Output voltage is regulated by using double wound dimmer Wider Input voltage range: 155 VAC - 502 VAC Input voltage range: 260 VAC - 450 VAC Switching devices are Semiconductors like Thyristors and Triacs which improves the reliability of the system. Switching device is Relay which is a electro-mechanical device & is less reliable as compared to semiconductor devices. No moving part inside and is a fully electronic unit. Carbon brushes generate sparks and Gear assembly makes noises. It is prone to frequent wear and tear that requires regular maintenance. Correction speed is very fast, almost 1000 V/Sec. Rate of correction is slow, almost 30 V/Sec. Response time is higher Poor Response time No cooling oil required Oil cooling is messy & is required to be changed periodically TECHNICAL SPECIFICATIONS Item Capacity Type Input Voltage Range Input Frequency Power Factor at Full Load Input Current Harmonics Wave Form Output Voltage Correction Speed Response Time Efficiency at Full Load Load Power Factor Crest Factor Distortion Max Output Current Over Load Protections Control Transformers Bypass Enclosure Metering / Indication General STATIC VOLTAGE REGULATOR • 5 KVA to 200 KVA • Control circuitry of Static Voltage Regulator is based on micro controlled and fully solid state power stage.
