Our 120KVA AC Three Phase Voltage Stabilizer (SBW series) is a
heavy-duty, high-performance automatic voltage regulator (AVR)
engineered for global industrial, medical and renewable energy
applications. With a standard 120KVA rated capacity and fully
customizable power range, it delivers stable, precision voltage
regulation for 50/60Hz 3 phase power systems, featuring a wide
304-456VAC input range and fixed 380VAC output at ±2% accuracy.
Designed to seamlessly handle inductive, capacitive and resistive
loads, it is the ideal AVR solution to protect sensitive industrial
equipment from harmful voltage fluctuations. Widely trusted by
electrical engineers, factory operators and medical facility
managers worldwide, it is perfectly suited for factory power
distribution, CNC machine tools, photovoltaic systems, EV charging
stations, hospital precision equipment, generators, industrial
motors and power transmission infrastructure.
Key Features & Competitive Advantages
This 120KVA 3 phase voltage stabilizer delivers industry-leading
performance with high precision, ultra-fast response, long service
life, low losses, full capacity operation and a wide voltage
regulation range. Core components include a high-power drive motor
for fast brush voltage regulation, high-conductivity double carbon
brushes with minimal abrasion, full purple copper winding for
accurate voltage stabilization, and a premium compensation
transformer with high-grade raw materials for maximized regulation
efficiency. It features a multifunctional LCD display for real-time
voltage, current and fault monitoring, integrated brake wheels for
easy mobility, optimized heat dissipation with efficient cooling
fans, industrial-grade switches, and high-insulation reliable
terminals. Comprehensive protection functions include over/under
voltage, overload, short circuit, over temperature, phase loss,
reverse phase, frequency protection and neutral line missing alert,
with switchable power supply/bypass working mode.
