What is an Active Voltage Conditioner?
An Active Voltage Conditioner is an inverter-based system that protects sensitive industrial and commercial loads from voltage disturbances. It provides fast, accurate voltage sag correction plus continuous voltage regulation and load voltage compensation. The AVC is a flexible device that can be used in multiple applications.
It has an operating efficiency exceeding 98% and provides extremely fast response to three-phase sags down to 50% nominal voltage, and single-phase sags down to 25% nominal voltage. Standard models are optimized for sag correction, voltage balance, and flicker reduction.
The larger Medium Voltage AVC is an ideal solution for complete facility protection. Its standard outdoor enclosure saves valuable indoor floor space. While the low voltage units can be applied to a process line or a specific critical load. Outdoor or enclosed models may be provided per site requirements.
| 10% +/- sag/surge: | Continuous wear on PLC’s, boards, line equipment, motors, lasers, process equipment |
| 20% – drop in voltage: | Considerable spike in amperage due to the low voltage, may see long term or immediate damage to equipment |
| 50% – drop in voltage: | Will appear to be outage, flicker or drop of lights. Considerable amperage spike to all loads, damaging. |
| 80% drop in voltage: | Power loss occurs, may be gradual sag if on one phase. Damaging to all Electronic Equipment. |
The following is what an AVC (Active Voltage Correction) System can provide for sag activity.
Voltage Correction Chart (95%+ Sags occur in a single phase of power)
| 10% +/- sag/surge | 10% +/- sag/surge regulation AVC corrects to nominal power voltage |
| 20% – drop in voltage (Sag to 80%nv) | AVC corrects to 100%, 3 phase for 3+ minutes, 1 phase Continuous |
| 50% – drop in voltage (Sag to 50%nv) | AVC corrects to 90% 3 phase for 1 minute, 1 phase 100% continuous |
| 80% drop in voltage (Sag to 20% nv) | AVC corrects 1 Phase 100% continuous |
3 phase Sag more than 70% is considered outage. Unit will still correct but not in acceptable voltage output window.

Have an ICP site survey done to survey your facility and install a power metering device.
When you install equipment that will correct power and hold voltage within your facility, you will be providing your facility with protection against all outside influences of power. Halting wear and tear on other equipment in the facility by having stable voltage and power factor is the goal. The long term positives are lowered operations and maintenance costs by limiting voltage and amperage anomalies inside the facility. It is common to vet these issues by installing a monitoring device at the service entrance of the facility utility power. This is a low-cost method to really understand these issues and to make a proper diagnosis.
We are available to review electrical one-lines, Power Reports, Demand Usage, and any other data on your facility power.
