Typical products for this category, not a claim about any one company’s range.

What are servo stabilizers?

A servo voltage stabiliser holds the output voltage steady when the incoming supply rises and falls. A motor-driven servo mechanism moves a carbon brush along a transformer winding to correct the voltage. Servo stabilisers protect machines, CNC tools, compressors and commercial plants, in single- and three-phase ratings and in air-cooled and oil-cooled designs. Isolation transformers and line reactors are related power-conditioning products.

How to choose

  1. Measure the supply: the range of voltage you actually see and how fast it changes, since a stabiliser must cover that range.
  2. Calculate the load in kVA, add a margin for starting current of motors, and choose a rating above it.
  3. Choose single-phase or three-phase, and whether the three phases are corrected independently or together.
  4. Pick the cooling: air-cooled units suit small ratings; oil-cooled units suit larger ratings and dusty or hot places.
  5. Check the output accuracy and the correction speed, which matter for sensitive equipment.
  6. Ask about the winding material and the brush and servo motor, since these are the parts that wear.
  7. Look for protections: overload, over and under voltage cut-offs, and a bypass switch.
  8. Confirm warranty, service response and the availability of spare brushes and motors.
  9. Ask for a sample installation at a similar plant and speak to the user about how often the brushes and servo motor needed attention and how quickly the supplier responded.
  10. Check that the unit’s dimensions, weight and cooling suit the space you have, and that cable entry and the bypass switch can be reached safely.

Where it is used

Frequently asked questions

How do I choose the kVA rating?

Add up the connected load in kVA, allow for motor starting current, and choose a stabiliser rated above it. A supplier can check your load list.

Servo or static stabiliser?

Servo stabilisers are common for larger loads and give accurate correction; static units have no moving parts and respond faster but cost more at large ratings.

Air-cooled or oil-cooled?

Air-cooled units are used at smaller ratings; oil-cooled units handle larger loads and tough conditions better.

What should I send for a quotation?

The load in kVA, the phase, the supply range you measure, the site conditions and any protection features you need.

How often should a servo stabiliser be serviced?

Brushes, rollers and servo motors wear with use. Follow the supplier’s schedule and keep the unit clean and ventilated.
