AC Voltage Regulators for Power Control

Maintaining stable voltage is critical to ensuring the safe and efficient operation of electrical systems. At United Automation, our AC voltage regulators are engineered to deliver precise power regulation, protecting equipment and improving energy performance in industrial and commercial environments.

Our range of compact power regulators is ideal for applications where consistent voltage is essential. These units are trusted by engineers, facilities managers, OEMs, and commercial businesses across the UK and beyond.

What Are AC Voltage Regulators?

AC voltage regulators are electronic devices that automatically maintain a constant voltage level to electrical equipment. They help regulate fluctuations in supply voltage and ensure that the connected load receives stable and controlled power.

These regulators are particularly useful in environments where voltage stability is critical for both safety and performance. Over- or under-voltage conditions can cause damage, downtime, or reduced equipment lifespan—issues that AC voltage regulators help to eliminate.

Key Features:

• Precise Output Control: Accurately regulate output voltage to match your system’s needs.
• Compact Design: Easy to integrate into panels and enclosures.
• Rugged Build: Designed for industrial reliability and long service life.
• Versatile Applications: Suitable for resistive and inductive loads.
• Adjustable Output: Fine-tune voltage for specific requirements.

Models typically offer a wide voltage input range and are engineered to suit different power environments. With fan-free designs, low maintenance, and robust casing, these regulators provide dependable performance.
