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.

ApplicationsThe 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
