Sure-Volt Voltage Regulator

The Sure-Volt voltage regulator - power conditioner provides the broadest range of protection available to guard your valuable equipment and maximize your bottom line:

  • Industry-leading overload capacity for compatibility with all loads types
  • Built-in surge suppression for surges and spikes
  • Line isolation minimizes transient events and noise
  • Transformer shielding further reduces line noise to deliver clean power
  • Very fast response quickly corrects under/over voltage, sags, and swells
  • Independent phase regulation to correct voltage imbalance
  • Input circuit breaker protects against damaging overcurrent
  • High fault clearing capacity permits reliable system operation
  • Failsafe electronic bypass keeps the load powered

Sag Fighter

The Sag Fighter sag ride-through conditioner (dynamic voltage restorer) protects sensitive equipment from deep voltage sags without the hassle, high costs and high maintenance of UPS units or mechanical energy storage devices. One and two phase sags down to 30% of nominal voltage and three phase sags down to 60% are corrected independently by phase for magnitude, waveform and phase angle.

Operating with 99% efficiency in its normal mode, the Sag Fighter monitors the incoming voltage and when indications of a sag are detected it initiates corrective measures within 1/8 cycle. The Sag Fighter also includes built-in surge suppression and circuit breaker to provide a complete package of protection.

Ideal for semiconductor, plastics and other industrial applications sensitive to voltage disturbances originating from the electric grid, Sag Fighter is about one-half the price of capacitor-based, high voltage dynamic voltage restorers. And, since the Sag Fighter operates at low voltage, it can be placed closer to the loads to provide additional protection from disturbances that might be generated within the facility, downstream of the distribution transformer.

When it comes to protection against deep voltage sags, the The Sag Fighter has the only technology that provides "unambiguous sag protection". Other technologies make you play guessing games like, "how long, how often, what load, what power factor?". The Sag Fighter eliminates the guessing games because the answer to these questions is, "it doesn't matter".

Mini-EVR Voltage Regulator

The Mini-EVR is the single phase power conditioner - voltage regulator that saves you money!

Based on the same technology found in UST's popular Sure-Volt power conditioner, the Mini-EVR provides the same very fast response, high overload capacity, industrial-grade durability and easy application as its big brother. The Mini-EVR is designed for small, single phase loads and is packaged in a smaller, lower cost configuration for indoor or outdoor application. But, most importantly, the Mini-EVR offers superior protection from power quality problems without busting your bottom line with high energy costs like traditional power conditioners.

For more than a half century, the ferroresonant transformer (also called constant voltage transformer or CVT) has been the standard for small, single phase power conditioning applications - and the technology has changed little since it was first developed. While the CVT performs well, two characteristics are immediately noticeable; they are hot and noisy. The heat and noise are more than annoying, they are energy dollars being wasted because of poor efficiency.

The Mini-EVR operates at 99% efficiency: period. The efficiency is unaffected by load, load power factor or load type. On the other hand, a CVT frequently operates at efficiencies as low as 50% because of various application characteristics. The difference in efficiencies means one thing - money wasted. Some typical dollar savings that can be realized by using the Mini-EVR instead of a CVT are shown in the figure.

The Mini-EVR saves you money from the first day for new applications, but replacing an existing CVT can also let you keep more of your energy dollars. Depending on the application, the payback in energy savings by replacing a CVT with the Mini-EVR typically ranges from 6 to 24 months.
