Fushin 3-Phase Voltage Stabilizer – 260V–430V Input

Fushin 3-phase voltage stabilizers with a wide 260V–430V input range are designed for three-phase electrical systems where the incoming voltage can fluctuate significantly around the nominal 380V level.

This voltage range is suitable for factories, manufacturing facilities, industrial plants, workshops and other three-phase electrical systems where the input voltage may drop below 320V during periods of high demand.

Fushin offers multiple capacity options for this product group, covering applications from smaller three-phase loads to large industrial power systems.

For an overview of the complete product range, see Fushin 3-Phase Voltage Stabilizers.

What Is a 260V–430V 3-Phase Voltage Stabilizer?

A 260V–430V 3-phase voltage stabilizer is an automatic voltage regulation device designed for electrical systems where the input voltage can vary over a wide range.

Compared with a narrower 320V–430V input range, the 260V–430V range is intended for systems where the incoming voltage can fall significantly below 320V.

Fushin's product range includes models with specifications such as 260V–420V input and 380V output, depending on the model. Therefore, the actual operating range should always be checked against the technical specifications of the selected product.

Basic Specifications

Product specifications may vary between models. Always check the individual product specification before ordering.

When Should You Choose a Wide 260V–430V Input Range?

The wide input range should be considered when the actual electrical supply can drop significantly below 320V.

Typical situations include:

• Voltage drops during peak production hours.

• Long electrical distribution lines between the transformer and the load.

• Industrial areas with high simultaneous power demand.

• Factories operating multiple high-power machines.

• Three-phase systems where the input voltage varies significantly during the day.

• Electrical systems where the lowest measured voltage can fall below 320V.

Before selecting a stabilizer, measure the actual input voltage during both normal and peak-load conditions.

260V–430V vs. 320V–430V: Which Input Range Should You Consider?

The main difference is the lower operating limit.

If your measured voltage drops below 320V, a wider input range may be more appropriate.

If the input voltage remains comfortably above 320V, the 320V–430V range can also be considered.

For systems where the voltage can rise significantly above 430V, see the 350V–500V input range.

Fushin 3-Phase Voltage Stabilizer with 380V Output

The 260V–430V category is primarily intended for three-phase systems requiring a regulated 380V output.

Actual specifications vary by model. For example, the Fushin 100KVA model FS3.II.380V-100K is specified with a 260V–420V input and 380V output, while the 300KVA model FS3.II.380V-300K is also specified for 260V–420V input and 380V output.

For this reason, the exact input range and output specification should be checked on the individual product page before ordering.

Applications of 260V–430V 3-Phase Voltage Stabilizers

Factories and Manufacturing Facilities

The wide input range can be useful for factories where the three-phase supply voltage fluctuates significantly during production.

Industrial Machinery

A regulated power supply can help equipment operate within the voltage range specified by the equipment manufacturer.

Motors and Industrial Loads

The stabilizer can be applied to systems supplying motors, pumps, fans and other three-phase loads, subject to the electrical requirements of the equipment.

Long-Distance Electrical Distribution

Voltage drops can become more noticeable in electrical systems with long distribution distances or high load demand. A wide input-range stabilizer can be considered when measurements show that the supply voltage falls significantly below the nominal level.

Why Choose a Wide Input Range?

A wider input range provides more operating margin when the incoming voltage fluctuates substantially.

For example, if a factory normally receives approximately 350V but the voltage occasionally falls toward 280V during peak production, a 320V–430V stabilizer may not be suitable for that condition. A wider input range should instead be evaluated.

However, a wider input range should not be selected simply because it is wider. The correct choice should be based on actual voltage measurements and the electrical characteristics of the system.

How to Select a 260V–430V 3-Phase Voltage Stabilizer

Step 1: Measure the Minimum Input Voltage

Measure the voltage at the stabilizer input during the period when the electrical load is highest.

Step 2: Measure the Maximum Input Voltage

Record the highest input voltage to determine whether the selected operating range is suitable.

Step 3: Determine the Required Output

For a three-phase 380V electrical system, select a model with the required 380V output configuration.

Step 4: Determine the Required Capacity

Consider:

• Total operating load.

• Actual operating current.

• Motor starting current.

• Variable-frequency drives.

• Electronic equipment.

• Future load expansion.

Step 5: Compare the Input Ranges

• Input can fall below 320V → consider 260V–430V.

• Input mainly remains between 320V and 430V → consider 320V–430V.

• Input can exceed 430V → consider 350V–500V.

Frequently Asked Questions

What is a 260V–430V 3-phase voltage stabilizer?

It is a three-phase automatic voltage regulation system designed for electrical installations where the input voltage can fluctuate over a wide range. The exact operating range depends on the selected model.

Is 260V–430V better than 320V–430V?

The two ranges are designed for different electrical conditions. If the input voltage can fall below 320V, the wider input range should be considered. If the supply remains mainly within 320V–430V, the narrower range may be sufficient.

What happens if the input voltage falls below 320V?

A stabilizer with a lower minimum input voltage should be considered. This is one of the main reasons for choosing the 260V–430V product group.

What if the input voltage exceeds 430V?

If the supply frequently exceeds 430V, the 350V–500V input range should be evaluated after measuring the actual electrical conditions.

How do I select the correct capacity?

The required capacity depends on the total operating load, operating current, motor starting current, load characteristics and expected future expansion.
