AVR/IVS (VOLTAGE STABILIZER)

Automatic Voltage Regulation You Can Rely On

At Integrated Power & Engineering, we work closely with factories, hospitals, commercial buildings, and infrastructure projects that face one common challenge every day—unstable voltage.

In Bangladesh, low voltage during peak hours, sudden surges, and frequent fluctuations are more than an inconvenience. They damage equipment, disrupt operations, and shorten the life of expensive machines. Our AVR / IVS Voltage Stabilizers are designed to solve exactly this problem by delivering steady, reliable voltage to your electrical system, no matter how unstable the incoming supply may be.

What an AVR / IVS Really Does

An AVR / IVS Voltage Stabilizer continuously monitors your incoming power and automatically corrects voltage variations before they reach your equipment.

It quietly protects your system from:

  • Low voltage that overheats motors and trips machines
  • Over-voltage that damages electronics and control panels
  • Sudden dips and surges that interrupt production

Whether you need to protect one critical machine or an entire facility, we design stabilizers that fit your real operating conditions—not generic assumptions.

Built Around Your Actual Load

No two sites have the same voltage problem. That’s why we don’t believe in one-size-fits-all stabilizers.

Capacity

  • From 1 kVA to 2000+ kVA, designed around your actual connected load and future expansion

Input Voltage Range

  • Custom input ranges such as ±15%, ±20%, or wide-range designs
  • Matched to the fluctuation pattern you experience on-site

Output Voltage

  • Stable output set to your requirement
    (220 V / 230 V / 400 V / 415 V)
  • Tighter regulation available for sensitive and mission-critical loads

Phase & Frequency

  • Single-phase or three-phase
  • 50 Hz operation

Technology That Matches the Job

Depending on how fast and how critical your voltage correction needs to be, we offer:

  • Servo-controlled stabilizers for industrial and high-capacity applications
  • Static stabilizers for fast response and highly sensitive equipment

Cooling can be air-cooled or oil-cooled, selected based on rating, duty cycle, and site environment.

Protection That Actually Matters

Our stabilizers don’t just regulate voltage—they help protect your entire electrical system:

  • Over-voltage and under-voltage protection
  • Overload and short-circuit protection (as required)
  • Surge protection options
  • Manual or automatic bypass for maintenance or emergency operation
  • Clear alarms and indications so your team always knows system status

Enclosures are available for indoor or outdoor installation, with IP ratings selected to suit real site conditions.

Why Stable Voltage Makes a Real Difference

When voltage stays within limits, you’ll notice:

  • Motors run cooler and last longer
  • CNC machines and PLC systems operate more accurately
  • Medical and laboratory equipment remain reliable
  • Fewer nuisance trips and unplanned shutdowns
  • Lower maintenance and replacement costs over time

It’s not just about protection—it’s about smooth, predictable operation.

Where Our Stabilizers Are Commonly Used

  • Industrial plants and manufacturing lines
  • Commercial buildings and shopping complexes
  • Hospitals, diagnostic centers, and laboratories
  • Data centers, telecom, and IT facilities
  • Hotels, airports, metro and rail projects
  • Elevators, HVAC systems, CNC and machine tools

If your site regularly suffers from voltage fluctuation or low voltage, an AVR / IVS can make an immediate difference.

Why Clients Choose Integrated Power & Engineering

  • We design around your site, not a standard table
  • We use reliable components proven in local conditions
  • Our focus is on protection, reliability, and long service life
  • You get local engineering support in Bangladesh
  • Suitable for single equipment or complete facility stabilization

What is the difference between AVR and IVS? +
AVR generally refers to automatic voltage regulation systems for voltage correction. IVS often refers to industrial voltage stabilizers designed for higher capacity and heavy-duty applications. Selection depends on load size and duty requirement.
How do I choose the stabilizer capacity (kVA)? +
Capacity depends on your total connected load, starting current (motors), and future margin. A site load list helps determine the correct kVA rating and phase type.
What input voltage range should I select? +
The input range is selected based on actual fluctuation at your site (low voltage and high voltage patterns). Wider input range is recommended where fluctuation is frequent.
Is a three-phase stabilizer required for factories? +
Yes, most industrial systems require three-phase stabilizers to stabilize facility-wide distribution and protect motors, MCC panels, and process equipment.
Does a stabilizer help protect equipment from surges? +
A stabilizer helps regulate voltage variation; surge protection can be added as an extra layer depending on your risk profile. We can include protective options as needed.
Can the stabilizer handle motor starting current? +
Yes, stabilizers can be designed to handle motor starting currents, but it must be considered in sizing and selection to avoid overload.
Do you provide bypass arrangements? +
Yes. Manual or automatic bypass can be provided based on system design, ensuring maintenance without interrupting supply.
Do you provide installation and support in Bangladesh? +
Yes. We provide local technical support for installation guidance, commissioning assistance (project-based), and after-sales service support.
