Frequently Asked Questions
What is a Single Phase Servo Voltage Stabilizer?
It is a precision automatic voltage regulator designed for single-phase electrical lines (230V AC). It uses a microprocessor controller and motor-driven auto-transformer to deliver constant 230V ±1% output regardless of fluctuating line voltage.
What is the difference between single phase and three phase servo stabilizers?
Single phase stabilizers regulate a single 230V AC line for smaller loads or single-phase equipment. Three phase stabilizers regulate 415V AC 3-phase lines, balancing all three phases independently for heavy industrial machinery.
How do I select the right kVA rating for my equipment?
Calculate the total wattage or Ampere load of your connected equipment, add a 20–25% safety margin, and select the corresponding kVA rating. Contact our technical team for free sizing consultation.
