Questions & Answers for AVS-50KVA Automatic Voltage Regulator (1P)
It is a 50 kVA automatic voltage stabilizer (AVR) designed to correct unstable high or low incoming grid voltage and deliver a safe, steady voltage to connected equipment. 50kva-avs-1p
With a typical power factor of around 0.8, a 50 kVA stabilizer supports roughly 40 kW of active electrical load.
AVS-50KVA units are commonly manufactured as three-phase systems (supporting 380V/400V lines), though single-phase high-capacity variants also exist depending on your specific power distribution setup.
Standard protections include over-voltage, under-voltage, overload, short-circuit, and phase-failure/phase-lack protection to protect both the stabilizer and your machinery.
Most models handle a wide input window (such as 304V–456V line voltage for three-phase systems), though exact thresholds vary by manufacturer design.
Yes. Many AVS-50KVA units include a built-in bypass switch allowing you to route raw grid power directly to your load during maintenance or unit servicing.
It typically uses a motorized servo system with carbon brushes or a static solid-state (SCR) design to automatically adjust turns ratio and stabilize output.
Modern AVS units feature digital LED or multi-functional LCD screens showing real-time input voltage, output voltage, load current, and working status.
It is meant for indoor use in clean areas where ambient temperatures stay between -5°C and +40°C, away from excessive dust, corrosive gases, or high humidity.
It is used for CNC machines, medical imaging/X-ray systems, telecommunication equipment, large server rooms, and heavy commercial or industrial office setups.
