Voltage Stabilizers

A voltage stabilizer corrects grid voltage dips and surges and supplies equipment with steady voltage. PES POWER supplies Turkish-made VARSAN stabilizers: single-phase models rated at 3.5–50 kVA and three-phase models rated at 10.5–1200 kVA.

Output voltage accuracy is ±1%, efficiency exceeds 98% at full load, and a mechanical bypass allows maintenance without disconnecting consumers.

When a stabilizer is needed

  • Voltage at the site regularly drops or rises above normal, especially at peak times.
  • Equipment is sensitive to power quality: CNC machines, medical equipment, refrigeration and process lines.
  • The site is supplied through a long line or a weak transformer.
  • The load is unevenly distributed between phases: three-phase models regulate each phase independently.

Stabilizer or UPS?

A stabilizer corrects voltage, but the load will stop during a total grid outage. A UPS provides both stable voltage and battery runtime.

If equipment shutdown is acceptable, a stabilizer is sufficient. Otherwise, an online UPS is needed.

At sites with a highly unstable grid, a stabilizer is installed upstream of the UPS so batteries are not used for every voltage dip. We will help select the right option for your facility.

Single-Phase and Three-Phase

Output voltage accuracy of ±1%, efficiency above 98% at full load, and mechanical bypass.

SINGLE-PHASE

220 V

3.5–50 kVA

For single-phase loads. Standard input voltage range: 175–265 V.

THREE-PHASE

380 V

10.5–1200 kVA

For three-phase loads with independent regulation of each phase. Standard input voltage range: 300–460 V.

The catalog also includes low-input-voltage models. Regulation range, power and configuration are agreed during selection.

Frequently asked questions

How do I select a stabilizer's rating?

From the total load power with a margin for starting currents. Send us an equipment list and we will calculate it.

Are configurations available for very low input voltage?

Yes. The input voltage range and configuration are agreed during selection.

What is the warranty?

The standard warranty for VARSAN stabilizers is 1 year and can be extended by agreement.
