Overview
Automatic Voltage Regulation for Industrial & Commercial Facilities
Voltage fluctuations, sags, and surges are a leading cause of equipment damage, production downtime, and premature failure in industrial and commercial facilities. An automatic voltage regulator continuously monitors and corrects supply voltage, delivering a stable, clean output regardless of input conditions.
MEGI Consultancy — a U.S.-based brand — sources and supplies industrial-grade automatic voltage regulators in servo motor and static thyristor configurations, matched to the facility load profile, correction range requirement, and communication infrastructure.

FAQ
Frequently Asked Questions
What is the difference between servo and static voltage regulators?
Servo motor regulators use a motorized variac for continuous correction with a wider input range (±25%) and higher output accuracy (±0.5%). Static thyristor regulators have no moving parts, faster response (20ms), and lower maintenance requirements — ideal for sensitive loads requiring rapid correction.
What kVA range is available?
Both servo and static configurations are available across a wide kVA range for three-phase and single-phase applications. Reference models include 2500 kVA (servo) and 1500 kVA (static). Specific capacity requirements are confirmed as part of the project specification process.
Do these voltage regulators support Modbus TCP/IP?
Yes. Both servo and static models support Modbus communication via RS485 as standard. SNMP over Ethernet (TCP/IP), CANBUS, and dry contact outputs are also available, enabling integration with BMS, SCADA, and network monitoring platforms.
What protection features are included as standard?
Standard protection includes input fuse or MCCB, 40kA lightning surge protection, phase sequence protection, overload protection, over and under voltage protection, over temperature protection, and short circuit protection. Automatic and manual bypass switches are included on both types.
What certifications do these AVRs carry?
CE marking, ISO 9001, 2014/35/EU Low Voltage Directive, and 2014/30/EU EMC Directive compliance are standard on both servo and static models. A 2-year warranty is included.
