TSi Sag-Free / Fluctuation-Free Power Conditioner

TSi-SFCube Sag-Free Power Conditioner

TSi-SFCube is a sag-free and fluctuation-free power conditioning system designed to protect sensitive electronic and industrial equipment from voltage sags, surges and routine voltage fluctuations. It provides fast AC voltage compensation so that connected equipment receives a regulated output supply during common mains voltage disturbance events.

The SFCube is suitable for equipment where even a short voltage dip can cause PLC reset, machine trip, process interruption, electronic card failure, data corruption or production loss. It is available in single-phase and three-phase versions for different site and load requirements.

Function Sag and surge voltage compensation

Technology IGBT-driven AC-AC compensator

Response Typical compensation within 20ms

Versions Single-phase and three-phase models

Product Overview

Voltage sags are one of the most common causes of nuisance tripping in modern electrical systems. Many electronic loads can tolerate normal supply variation, but they may fail or reset when the voltage drops for even a short duration. The SFCube is designed to reduce this risk by compensating the voltage in real time.

The system continuously monitors the incoming AC voltage against a nominal reference. When it detects a sag or surge, the high-frequency IGBT compensator adds or subtracts voltage so that the connected load receives a regulated 230V or 400V output, depending on the system configuration.

Positioning: Sag-free power conditioner for sensitive equipment requiring fast voltage sag and surge compensation without routine maintenance associated with mechanical correction systems.

How TSi-SFCube Works

Stage	Operation	Purpose
1. Measure Incoming Voltage	The system monitors the incoming AC voltage and compares it against the nominal voltage reference.	Detects sag, surge or fluctuation conditions.
2. Detect Disturbance	Voltage deviation is identified by the control system.	Determines whether voltage must be boosted or reduced.
3. IGBT Compensation	The high-frequency IGBT-driven compensator injects or subtracts compensation voltage.	Restores the output voltage close to nominal level.
4. Regulated Output	The connected load receives regulated 230V / 400V output depending on system type.	Helps prevent equipment trips and electronic disturbance.

Simple explanation: When the input voltage drops, SFCube adds voltage. When the input voltage rises, SFCube subtracts voltage. The objective is to keep the output stable for the connected equipment.

SFCube vs Conventional Voltage Stabiliser

Comparison Point	Conventional Voltage Stabiliser	TSi-SFCube
Correction Method	Often mechanical, tap-changing or slower correction depending on design.	Static IGBT-driven AC-AC compensation.
Sag Response	May be too slow for short sag events affecting electronics.	Designed for fast compensation around 20ms.
Routine Voltage Fluctuation	Corrects voltage but may not respond fast enough for sensitive loads.	Always-online compensation corrects fluctuations in real time.
Maintenance	May involve moving parts, contact wear or periodic servicing depending on technology.	Static technology supports lower maintenance requirements.
Best Fit	General voltage stabilisation.	Sensitive electronic equipment, automation, CNC, robotics and process systems affected by voltage sags.

When to Use SFCube

SFCube is useful when the site experiences voltage sag events that are too fast or too severe for normal voltage regulation equipment, but where the load does not necessarily require long battery backup from a UPS. It is especially useful for production loads where a short voltage dip can stop the machine and create expensive downtime.

When voltage sags cause machine trips or PLC resets.
When sensitive electronic equipment is affected by incoming supply fluctuation.
When fast sag correction is required without relying on mechanical regulation.
When the site needs voltage sag ride-through support but not full battery backup.
When production downtime from short supply dips is expensive.
When power quality improvement is needed before CNC, robotics, automation or process control equipment.

Project Selection Guide

Correct sizing and application review is important because sag compensation depends on the load, sag depth and duration. For critical applications, it is recommended to measure the actual power quality profile before final selection.

Confirm system voltage: single-phase 230V or three-phase 400V.
Confirm load kVA, running current, inrush current and dynamic load behaviour.
Measure typical sag depth, sag frequency and sag duration at site.
Confirm whether the load includes VFDs, servo drives, regenerative loads or high inrush equipment.
Confirm the required ride-through requirement based on ITIC curve or equipment immunity needs.
Confirm bypass requirement, protection coordination, enclosure type and installation location.
Confirm ventilation, heat clearance, cable entry and maintenance access.

Engineering note: For production-critical loads, a PQube 3 or equivalent power quality analyser should be used to capture real sag events before final SFCube sizing.

Integration with PQube 3 and IoTWatt 4.0

SFCube can be combined with power quality monitoring to verify incoming sag events and confirm output voltage improvement. In a complete monitoring architecture, PQube 3 can capture the voltage disturbance waveform while IoTWatt 4.0 can provide energy, equipment operation and incident visibility.

Install PQ monitoring before and after SFCube where verification is required.
Use PQube 3 to capture sag, surge and waveform evidence.
Use IoTWatt 4.0 to correlate power events with equipment operation and energy data.
Track machine trips before and after SFCube installation.
Support energy audit, EECA reporting and reliability improvement projects.
