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 applications. 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.
