SUNTEK SERVOMOTOR 8500VA Voltage Stabilizer
Precision servo motor voltage stabilization for homes, workshops and sensitive electrical equipment.
The SUNTEK SERVOMOTOR 8500VA is a high-precision automatic voltage stabilizer designed to protect electrical equipment from low voltage, overvoltage and unstable power supply conditions.
It operates within a wide input voltage range of 130–280V and maintains stable output voltage with an accuracy of ±3%. Smooth servo-driven regulation helps prevent abrupt switching and visible light flickering.
Key Features
Servo Motor Technology
The stabilizer uses a servo-controlled carbon brush that moves along the winding of a copper autotransformer, continuously adjusting the output voltage and maintaining stable 230V power.
High stabilization accuracy: ±3%
Smooth voltage regulation
Pure sine wave output
No abrupt relay switching
Suitable for pumps, boilers and sensitive electronics
Built-In MOV Surge Protection
SUNTEK SERVOMOTOR 8500VA features integrated surge protection based on a Metal Oxide Varistor (MOV).
The MOV reacts to dangerous voltage spikes caused by lightning, switching surges, power grid disturbances or line faults. It absorbs excess energy before it can reach the connected equipment.
For additional safety, the MOV is enclosed in a dedicated protective sleeve to help contain thermal effects under extreme conditions.
Dual Connection System
The updated design allows two connection options:
Schuko Socket
Convenient connection for household appliances and portable equipment.
Terminal Block
Reliable hardwired connection for permanent installations and higher-power applications.
Real-Time Monitoring
The front panel display shows all key operating parameters:
Input Voltage
Output Voltage
Load Current
Load Level
Reliable Internal Components
The stabilizer is built around a proven electromechanical design with durable internal components.
Intelligent Control Board
Monitors power parameters and controls stabilization in real time.
Precision Servo Motor
Moves the brush assembly along the autotransformer winding to correct voltage changes.
Copper Autotransformer
Designed for long-term operation under continuous load.
Dual-Turn Brush Contact System
The carbon brush contacts two winding turns at the same time, helping eliminate output interruptions during voltage correction.
Comprehensive Equipment Protection
The stabilizer protects connected equipment against:
Overvoltage
Undervoltage
Overload
Short Circuit
Overheating
Surge Spikes
Lightning-Induced Transients
Applications
SUNTEK SERVOMOTOR 8500VA is suitable for:
Refrigerators and Freezers
Washing Machines
Water Pumps
Septic Systems
Heating Equipment
Gas Boilers
Audio and Video Equipment
Sensitive Electronics
Workshops and Utility Rooms
For equipment with electric motors, a 20–30% power reserve is recommended to cover startup currents.
