Three Phase Servo Voltage Stabilizer

About Three Phase Servo Voltage Stabilizer

Sen & Pandit also offers Servo Voltage Stabilisers for 3 - phase systems. These usually have three single-phase servo stabilisers connected in STAR configuration for 3-phase application with individual sensing for each phase and to provide constant output in each phase even with unbalanced supply or unbalanced load.

Features

A versatile control panel at the top provides:

• A voltmeter with a selector switch which can monitor any line voltage
• Three ammeters to monitor output current continuously at each phase.
• A miniature load ON-OFF switch actuates an AC line contactor which in turn actuates the 3-phase load system.
• A reset switch counteracts tripping of supply to load. This switch will not reset the system unless source of tripping is removed

Automatic tripping of the load system in case of:

• Single Phasing
• Under or over range of input supply voltage in any phase.
• Over loading in any phase.
• Three voltmeters ( in each single phase unit) to monitor each phase to neutral voltage (both input and output) continuously.
• Buzzer to indicate input over voltage or under voltage in any phase.
• Manual setting facility.

High Performance Voltage Regulation

Engineered for precision and reliability, this stabilizer keeps voltage fluctuations in check within industrial and commercial setups. Correction speed and swift response minimize risk to sensitive equipment, ensuring consistent operation even during power variation. The use of copper wound transformers and microcontroller-based control systems guarantee stable output while offering overload protection and maintaining waveform quality.


Flexible Cooling & Robust Design

Customize your stabilizer with air-cooled or oil-cooled options, tailored to varying site requirements. The compact, floor-standing enclosure offers robust protection (IP21/IP23), designed for heavy-duty performance. Heavy-duty terminals and insulation resistance over 2 Mega Ohms assure longevity, making this system ideal for demanding industrial environments, even in conditions of high humidity and altitude.
