Industrial Grade 415V 120KVA Servo Type 3 Phase Automatic Voltage Regulator Stabilizer
The SBW-120KVA 415V Industrial Grade Servo Type 3 Phase Automatic Voltage Regulator delivers reliable power conditioning for manufacturing facilities and commercial installations operating under challenging grid conditions. Engineered with an exceptionally wide input voltage regulation range of 415V±20% (332V to 498V), this 120KVA stabilizer compensates for severe voltage fluctuations that frequently affect industrial zones, remote sites, and regions with unstable utility infrastructure. The intelligent LCD monitoring system provides operators with comprehensive real time data including input voltage, output voltage, load current percentage, operational status indicators, and fault diagnostic codes through a bright easy to read display panel. Supporting inductive loads such as motors, capacitive loads including power factor correction banks, and resistive loads like heating elements, the SBW-120KVA offers universal load compatibility that simplifies power management across mixed equipment environments in factories, telecommunications facilities, and commercial buildings.
Key Features- 415V±20% Ultra Wide Input Regulation Range: Accepts severe input voltage swings from 332V to 498V without compromising output stability, making this regulator indispensable for regions with chronically unstable power grids and industrial parks experiencing heavy load fluctuations throughout the day.
- Intelligent LCD Real Time Monitoring System: The multifunctional LCD panel displays simultaneous real time readings of all three phase voltages, load currents, working status, and fault conditions with on screen touch buttons for effortless parameter adjustment without requiring external programming devices or software.
- 120KVA Continuous Full Capacity Output: Featuring full purple copper column windings and high permeability silicon steel transformer core material, this unit delivers genuine 120KVA rated output continuously without derating, backed by oversized conductors that minimize resistive losses and operating temperatures.
- High Speed Servo Motor Voltage Correction: A precision high torque servo motor drives dual carbon brush assemblies across the autotransformer winding surface, achieving rapid voltage correction response that effectively handles transient fluctuations before they reach connected equipment.
- Robust Overload and Fault Protection: Comprehensive ten point protection architecture including over voltage cutoff, under voltage lockout, electronic overload detection, short circuit isolation, over temperature thermal shutdown, phase sequence verification, phase loss detection, frequency monitoring, neutral line supervision, and programmable time delay restart ensures complete system safety.
- Zero Waveform Distortion Output: Unlike electronic switching regulators, the servo mechanical regulation principle introduces no additional harmonic distortion or waveform clipping, delivering a pure sinusoidal output waveform identical in shape to the utility input but at precisely regulated voltage levels.
- Industrial Mobility with Brake Wheels: Heavy duty integrated brake casters allow single person repositioning across factory floors, while the lockable braking mechanism secures the unit firmly in place during operation, combining installation flexibility with operational stability.

The SBW-120KVA voltage regulator serves as a versatile power conditioning backbone across multiple industrial sectors. Manufacturing plants integrate these units to protect CNC machining centers, robotic welding cells, and automated assembly lines where voltage instability can cause dimensional inaccuracies and production rejects. Telecommunications base stations and mobile network towers in remote locations depend on this regulator to condition generator or weak grid power before feeding sensitive RF transmission and networking equipment. Commercial printing facilities utilize the regulator to maintain consistent motor speeds on high speed printing presses where voltage dips can disrupt registration alignment and waste expensive substrate materials. Water treatment and pumping stations benefit from the motor friendly output characteristics that extend pump service life and reduce maintenance intervals. Food processing lines, pharmaceutical production equipment, and textile manufacturing machinery all achieve improved productivity and reduced scrap rates when powered through this precision voltage stabilizer. Laboratory testing environments and calibration facilities particularly value the zero waveform distortion output for maintaining measurement accuracy on sensitive analytical instruments.
Packaging & Quality AssuranceEvery SBW-120KVA unit passes a comprehensive factory acceptance test protocol including full load capacity verification, protection function cycling, extended continuous operation burn in, and output accuracy calibration before release for shipment. The regulator is packaged in a custom reinforced wooden crate with high density foam corner protectors, vapor barrier polyethylene wrapping, and steel banding straps for maximum protection during international sea freight, air cargo, or land transportation. Our 12 month standard warranty covers all manufacturing and component defects, with replacement parts shipped at no charge for any warranty claims. Lifetime complimentary technical consultation is available by telephone and online channels, supported by an experienced engineering team capable of providing remote video diagnostic support, detailed installation guidance, and on site commissioning services for projects across all global markets including Central Asia, Southeast Asia, Africa, South America, and the Middle East.
