Automatic Voltage Regulator:

Series AVR

The Series AVR is a solid-state Automatic Voltage Regulator designed to protect your system against electrical brownouts, sags, surges, transients, and other electrical disturbances.  It has a small overall footprint, high-efficiency design, and power quality monitoring. This automatic voltage regulator utilizes solid-state microprocessor based regulation to adjust voltage, with a multi-shield computer grade transformer and filter to remove transients and noise. The combined effect is a regulating and shielded isolation transformer/system, which solves 99% of electrical disturbance problems.

AVR Benefits:

  • Solid-State Topology
  • Precision Voltage Regulation
  • Control & Fault Monitoring
  • PWM Inverter & Rectifier
  • Integrated Quiet Design
  • Vertical Configuration
  • Extended Voltage Range
As the use of power increases in our communities, utility companies have less and less control over the quality of power supplied to sensitive electronic equipment. The effects of unreliable power can cause irrecoverable damage to expensive manufacturing equipment, resulting in lost production time and/or products. Furthermore, the low output impedance of the transformer assures computer grade performance with excellent noise and transient attenuation. The AVR has 7 taps per phase, as well as, electronic switches to ensure tight voltage regulation to within +/- 3%.

The Series AVR is a high-efficiency design, which results in a lower operating cost. Sizes are available from 10 to 1000kVA. Optional internal manual bypass maintains the system isolation, voltage transformation, and power conditioning. There are numerous other options available including remote communications, as well as, NEMA enclosures for unforgiving locations.
