About the TSI Single Phase Active Voltage Regulator

In any industrial or mission-critical environment, maintaining continuous, reliable operation of equipment is essential. Yet, utility voltage instability (including voltage sags, surges, and overvoltage events) remains a persistent threat. Even brief voltage anomalies can result in productivity losses, data corruption, or costly equipment damage.



The TSI Single Phase Active Voltage Regulator is engineered specifically to counter these challenges. It continuously monitors incoming utility voltage and automatically adjusts it in real-time, maintaining output within a tight ±3% tolerance. Designed for high-reliability applications, it also incorporates internal surge suppression and load overcurrent protection, making it an ideal investment for industries where power quality cannot be compromised.

TSI Systems Vs. ABB Systems

While ABB Systems are widely recognized for their capabilities in lower voltage correction scenarios, TSI Systems provide solutions tailored for facilities requiring higher precision and broader correction ranges. The TSI Single Phase Active Voltage Regulator offers robust protection against a broader spectrum of voltage anomalies, including under- and overvoltage conditions, that can disrupt operations and damage sensitive systems.



For industries operating high-value equipment such as CNC machinery, robotics, extrusion systems, and medical instrumentation, the superior voltage stabilization capabilities and industrial-grade reliability of TSI Systems make them a preferred choice for critical environments where downtime is not an option.

Why Consider a TSI Single Phase Voltage Regulator

The primary reason to consider a TSI Single Phase Active Voltage Regulator is its ability to stabilize power for sensitive plant and process equipment impacted by unstable voltage. Whether dealing with manufacturing lines, high-speed drives, or precision robotics, voltage irregularities often lead to elevated maintenance costs, PCB failures, and system malfunctions.


Deploying a voltage correction system like the TSI unit protects against these risks, ensuring not only operational continuity but also reducing long-term maintenance expenses and equipment replacement costs.


The TSI regulator is well-suited for a variety of industrial applications, including but not limited to:

  • CNC Machinery
  • Drives
  • Extrusion Equipment
  • Medical Devices
  • Motors and Controls
  • Robotics
  • 3D Printing Systems

Even if it isn't downtime that you're trying to combat, voltage irregularities often lead to significantly higher maintenance costs. Overvoltages and surges, in particular, can cause PCB and board failures as well. Having a TSI active voltage regulator can dramatically reduce all of these problems, saving you money that can be funneled back into other areas of the business where it can do the most good.

Benefits of the TSI Single Phase Voltage Regulator

Precise Voltage Correction

One of the major advantages that comes with an investment in the TSI active voltage regulator comes down to just how precise this device is. Once the converter accurately measures the incoming voltage, it makes adjustments by either adding or subjecting (also referred to as bucking or boosting) the voltage to within +/- 0 to 3% of the output voltage range.

Operates Automatically

Once it is properly installed, the TSI active voltage regulator is notorious for being something of a "set it and forget it" device. You don't have to watch the weather to switch it on ahead of an upcoming storm. You don't have to tell it to do anything when voltage irregularities are detected. They're identified automatically, the correction happens in milliseconds, and you and your team members can keep right on working.

Quick Response Time

When used with high-speed power electronics, the TSI active voltage regulator has a response time of literally 10 milliseconds. This is the amount of time it takes to switch over from standard power to the voltage regulator and for the correction to take place. During this time, the load current path will not be broken.

Internal Surge Protection

Many people don't realize that situations where overvoltage is present and power surges are two different things, and protection against one doesn't necessarily protect against the other. Thankfully, the TSI active voltage regulator includes internal surge protection that safeguards expensive machines and other equipment (and helps reduce the risk of electrical fires and similar matters).

Noise Filtering

The type of built-in noise filtering offered by the TSI active voltage regulator isn't just one of the most common ways to reduce noise in a power supply–it's also among the most effective as well.

Wide Range of Applications

Beyond heavy manufacturing and robotics, the TSI active voltage regulator is ideal for medical laboratories, high-tech production facilities, and automated industrial systems. Its broad application range ensures all critical devices receive stable, clean power, essential for maintaining operational standards and protecting delicate electronics.

Low Maintenance

Engineered for reliability, the TSI voltage regulator has minimal moving parts, with the only active component being a cooling fan. Unlike systems with servo motors or mechanical relays, this design results in lower wear, reduced maintenance needs, and increased system uptime even in demanding industrial environments.
