Product Details
Brand:	GEESYS	Type:	Oil Cooled Servo Voltage Stabilizer
Series:	DSP Oil Cooled Servo Stabilizer	Dispatch:	Between 10-15 Days
Model:	GOCSVS-90-295465	Price:	INR 19000/-*

GEESYS Oil Cooled Servo Voltage Stabilizers are engineered to deliver precise voltage regulation, high efficiency, and long-term reliability for industrial, commercial, and critical applications across India. Designed with advanced Digital Signal Processor (DSP)-based control technology, these stabilizers ensure consistent output voltage even under extreme input fluctuations.

Our oil cooled servo stabilizers are three-phase, servo motor-controlled systems that maintain a stable output voltage by continuously correcting fluctuations through a buck-boost transformer mechanism. Each phase operates independently, making the system highly effective for unbalanced load conditions commonly found in industrial environments.

The stabilizer uses a single motherboard DSP controller for intelligent monitoring, fault protection, high-speed correction, and service-friendly diagnostics.

FAQs

1. What is a servo voltage stabilizer?

A servo voltage stabilizer is an automatic voltage correction system that maintains a steady output voltage for connected equipment when the incoming supply fluctuates.

2. How does a servo voltage stabilizer work?

It senses input voltage changes and corrects the output through a control circuit, motor-driven variac, and buck-boost transformer arrangement.

3. Why is a servo stabilizer used?

It protects motors, electronics, compressors, lifts, and industrial equipment from under-voltage, over-voltage, and unstable mains conditions.

4. Where are servo stabilizers commonly used?

They are commonly used in factories, hospitals, commercial buildings, CNC applications, lifts, printing units, data-sensitive installations, and selected residential loads.

5. What is the difference between servo and static stabilizers?

Servo stabilizers use electromechanical correction for high-capacity and rugged applications, while static stabilizers use solid-state electronics for faster correction in specific use cases.

6. How do I select the right servo stabilizer rating?

Selection depends on load kVA, single-phase or three-phase requirement, input voltage range, output accuracy needed, load type, and installation environment.

7. What input voltage range can a servo stabilizer handle?

The supported input range depends on the model and configuration. GEESYS offers different correction ranges based on site voltage conditions and load requirements.

8. Does a servo stabilizer require maintenance?

Yes. Periodic checks for mechanical movement, electrical connections, carbon brush condition, and overall enclosure cleanliness help maintain reliable long-term performance.

9. Can a servo stabilizer help protect against voltage spikes and surges?

It helps control abnormal voltage conditions, and surge protection can also be integrated or recommended depending on the installation risk profile.

10. Can GEESYS recommend the right servo stabilizer for my load?

Yes. Share your load details, phase type, input voltage condition, application, and site environment, and GEESYS can suggest a suitable servo stabilizer configuration.
