TSi Power Voltage Stabilizer / Automatic Voltage Regulator / Power Line Conditioner
TSi Voltage Stabilizer, Automatic Voltage Regulator & Line Conditioner
TSi voltage stabilizers and power line conditioners are designed to deliver stable, regulated AC power to sensitive industrial and electronic equipment. They help protect connected loads from voltage fluctuation, low voltage, high voltage, voltage sag, voltage swell, surges, spikes and electrical noise.
The range includes precision static voltage regulation solutions such as TSi VRP and TSi-200 automatic voltage regulators for single-phase and three-phase applications. These systems are suitable where battery backup is not required, but clean and stable AC power is important for reliable machine operation.
Product Type Voltage stabilizer, AVR and line conditioner
Technology Static / PWM regulation and automatic voltage correction
System Options Single-phase and three-phase configurations
Applications CNC, robotics, automation, medical, process and critical loads
Product Overview
Modern machines and electronic systems are increasingly sensitive to unstable mains supply. CNC machines, robotics, PLC panels, VFD-controlled equipment, printing machines, textile machines, packaging lines, medical systems, laboratory equipment and process controllers can malfunction when the supply voltage moves outside acceptable limits.
TSi voltage regulators help maintain a stable output voltage to the connected equipment. They are normally selected when the main problem is unstable voltage, voltage fluctuation or repeated sag / swell conditions, and where the load does not need to continue running from batteries during a full power outage.
Positioning: TSi voltage stabilizers are practical power conditioning solutions for sensitive equipment that needs stable AC voltage, but does not necessarily require battery backup.

TSi VRP Precision Static / PWM Voltage Regulation
TSi VRP is a precision PWM automatic voltage regulator and static line conditioner designed for critical equipment that requires fast and precise voltage correction. Unlike conventional servo stabilisers, the VRP uses solid-state PWM regulation technology with no moving regulating parts in the active correction system.
It provides fast, step-less voltage correction and tightly controlled output power quality for sensitive industrial, automation and microprocessor-based equipment.

Recommended Project Selection Process
Correct sizing and application review is important. A voltage regulator should be selected based on the real electrical load profile and site power quality condition, not only the machine nameplate rating.
- Measure incoming voltage variation and disturbance behaviour at the equipment supply.
- Confirm load kVA, running current, starting current, inrush current and regenerative behaviour.
- Confirm voltage system: single-phase, split-phase, three-phase Wye or Delta.
- Confirm required output voltage and acceptable voltage tolerance.
- Check whether the load includes VFDs, servo drives, high inrush equipment or dynamic loads.
- Confirm whether manual bypass, automatic bypass, alarm output or surge protection is required.
- Confirm enclosure, wall-mounted, floor-standing or panel installation requirement.
- Review heat, ventilation, maintenance access and cable entry requirements.
Engineering note: For CNC, robotics and process lines, it is recommended to review both voltage fluctuation and power quality event history before final voltage stabilizer sizing.
Integration with IoTWatt 4.0 and Power Quality Monitoring
A voltage stabilizer improves supply stability to the connected equipment. For complete visibility, it can be combined with power meters, PQube 3 power quality analyzers and IoTWatt 4.0 monitoring. This allows the site to see incoming voltage condition, regulated output behaviour and equipment energy profile.
- Monitor incoming voltage before the voltage stabilizer and regulated output after the stabilizer.
- Track equipment kW, kWh, demand and operating behaviour.
- Correlate machine trips with voltage events and power quality disturbances.
- Use PQube 3 or Class A power quality analyzers for sag, swell, transient and interruption investigation.
- Use IoTWatt 4.0 dashboards for energy visibility, event correlation and incident reporting.
- Support digital energy audits, EECA reporting and power quality improvement projects.
