Klass 3-Phase Automatic Voltage Regulator (KL-AVP3P)

The Klass 3‑Phase Automatic Voltage Regulator (Model KL‑AVP3P) is a heavy‑duty voltage stabilisation solution engineered for three‑phase electrical systems where power irregularities can damage sensitive or high‑load equipment. In environments that experience frequent voltage fluctuations, surges, or drops — such as industrial facilities, commercial buildings or larger residential setups — a 3‑phase AVR protects your investment by ensuring connected systems receive clean, stable and consistent power.

Rated to handle 3‑phase loads, the KL‑AVP3P automatically senses variations in incoming voltage and adjusts output to deliver the correct, regulated voltage to your appliances and systems. This protection helps prevent issues like motor overheating, electronic failure, data loss and premature wear that arise from unstable highs or lows in the mains supply.

With comprehensive over‑voltage, under‑voltage, overload and short‑circuit protection, this voltage regulator not only maintains stability but also disconnects power temporarily when conditions go beyond safe thresholds — protecting both the AVR itself and the attached equipment. Once the supply returns to acceptable levels, the regulator safely restores power with controlled sequencing to avoid stress on motors or electronics.

The robust build quality of the Klass KL‑AVP3P makes it suitable for residential three‑phase mains as well as commercial or light industrial environments. Typical applications include multiple air conditioning units, large freezers and refrigerators, industrial pumps, heavy machinery, data servers, workshop equipment and more — wherever high current and consistent voltage are critical.

Whether you’re safeguarding business equipment or heavy home appliances that rely on three‑phase supply, the Klass 3‑Phase Automatic Voltage Regulator (KL‑AVP3P) delivers reliable power regulation and peace of mind through advanced stabilization and protection technologies.
