Voltage Regulation
AVR Systems
Automatic Voltage Regulators and servo stabilizers that hold your supply voltage steady, protecting motors, machines and electronics from the high and low voltage swings common on local grids.
Problems we solve
- Low voltage at the end of long feeders
- Over-voltage during light-load hours
- Motor overheating and nuisance tripping
- Damage to CNC, medical and electronic equipment
Overview
Stable voltage for sensitive and heavy equipment
Voltage on many industrial and commercial feeders swings well outside equipment ratings during the day. Under-voltage makes motors draw more current and overheat, while over-voltage stresses insulation and destroys electronic power supplies.
DCPS supplies and installs single-phase and three-phase AVR and servo-controlled voltage stabilizers sized to your load and to the actual voltage range at your site. We log your incoming supply first, so the stabilizer input range and correction speed match real conditions rather than assumptions.
Units are installed with the right protection, bypass arrangements and earthing, and supported with routine maintenance of carbon brushes, contactors and control cards.
Why DCPS
Site loggingVoltage recorded before sizing
Wide input rangeCorrection matched to your actual supply
Balanced or unbalancedIndependent phase control where needed
Bypass readyMaintenance without shutting down the load

Our Process
How we solve voltage problems
01
Supply Logging
We record incoming voltage over a representative period.
02
Load Analysis
Connected load, starting currents and sensitive equipment are identified.
03
Sizing
AVR capacity, input range, correction speed and configuration are selected.
04
Installation
Unit installed with cabling, protection, bypass and proper earthing.
05
Maintenance
Periodic inspection and calibration keep the regulator accurate.

Where AVRs make the difference
FAQ
Frequently Asked Questions
What size of AVR do I need?
The AVR should be rated above your connected running load with margin for motor starting. We calculate this from your load list and logged data.
What is the difference between an AVR and a UPS?
An AVR corrects the voltage level while mains power is present. A UPS also provides backup during a complete outage. Many sites benefit from both.
Can one stabilizer protect my whole factory?
Yes, a large three-phase unit at the main incomer can protect the entire facility, though sometimes separate units for sensitive loads are more economical.
How fast does the AVR correct voltage?
Correction speed depends on the design. We specify a correction speed suited to how quickly your supply voltage changes.
