AVR / IVS Voltage Stabilizer – Automatic Voltage Regulation for Reliable Power | Integrated Power & Engineering
At Integrated Power & Engineering, we supply AVR/IVS (Voltage Stabilizer) systems engineered to deliver stable, regulated output voltage for sensitive and high-value electrical loads. In Bangladesh, voltage fluctuation, low voltage, and sudden surges can damage equipment, reduce efficiency, and increase downtime. Our Automatic Voltage Regulators (AVR) and Industrial Voltage Stabilizers (IVS) protect your electrical infrastructure by maintaining consistent voltage—improving performance, extending equipment life, and reducing failure risk.
Our stabilizers are suitable for industrial plants, commercial buildings, hospitals, data centers, and critical infrastructure where uninterrupted and stable voltage is essential.
Product Overview: What is an AVR/IVS Voltage Stabilizer?
An AVR/IVS Voltage Stabilizer is a power-conditioning system that automatically corrects incoming voltage variations to deliver a stable output. It protects electrical equipment from:
- Under-voltage and over-voltage
- Voltage surge and fluctuation
- Poor supply stability and frequent voltage dips
Depending on application and capacity, stabilizers can be designed as servo-controlled or static type, with monitoring and protection features suitable for both single equipment and whole-facility load stabilization.

FAQs
1) 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.
2) 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.
3) 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.
4) 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.
5) 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.
6) 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.
7) Do you provide bypass arrangements?
Yes. Manual or automatic bypass can be provided based on system design, ensuring maintenance without interrupting supply.
8) 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.
