Introduction

Built for PAN India applications, GEESYS stabilizers are trusted for rugged construction, superior protection mechanisms, and energy-efficient performance. 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 easy troubleshooting.

Key Features & Benefits

• DSP-based single motherboard PCB with 100 error logs and Real-Time Clock (RTC).
• Output voltage maintained at 400V with +/-1% / +/-2% accuracy.
• True RMS sensing for accurate voltage correction under dynamic load conditions.
• Over voltage, under voltage, overload, short circuit, phase failure, and phase reversal protection.
• 3-stage intelligent tripping with adjustable delay for low voltage, high voltage, and overload current.
• Oil-cooled system with multiple radiators, leak-proof oil tank, double side louvers, oil level indicator, drain plug, and filling cap.
• Busbar-based construction with aluminium wound series transformer, copper wound auto transformer, and SMC insulated output busbars.
• Built-in manual bypass system for uninterrupted power during maintenance or faults.

Frequently Asked Questions

What is an oil cooled servo voltage stabilizer?
It is a servo controlled voltage regulator that uses transformer-based correction and oil cooling to maintain stable output voltage for heavy industrial loads.

Which capacities are available?
Standard pages cover 45 kVA to 500 kVA, with higher capacities available on request.

Is it suitable for unbalanced load?
Yes. Independent phase correction makes it suitable for unbalanced industrial load conditions.

Does GEESYS provide manual bypass?
Yes. The built-in manual bypass supports maintenance continuity and emergency bypass operation.

How do I select the right input range?
Choose 295V - 465V for wider fluctuation, 340V - 480V for digital DSP models, or 360V - 460V for comparatively stable supply conditions. GEESYS can guide the final selection based on site voltage readings.
