COSIMAT C2.1 AVK AVR – Automatic Voltage Regulator

OverviewTheAVK COSIMAT C2.1 Automatic Voltage Regulator (AVR)represents cutting-edge voltage control technology designed specifically for synchronous alternators in generator applications. This compact, highly reliable AVR provides precise voltage regulation to ensure your generator delivers consistent, stable power output regardless of load variations or operating conditions. The COSIMAT C2.1 is AVK's standard production model, trusted by generator manufacturers, industrial facilities, data centers, hospitals, and commercial operations worldwide to maintain critical power quality and protect sensitive equipment from voltage fluctuations that can cause damage or operational failures.Engineered with advanced circuitry and robust components, the AVK COSIMAT C2.1 AVR offers two distinct methods of influencing alternator voltage output, including sophisticated under-frequency protection (U/F function) and under-speed protection capabilities. This dual-mode operation ensures your generator automatically adjusts voltage based on frequency variations, preventing over-excitation during startup and protecting the alternator from damage during abnormal operating conditions. Whether you're replacing a failed AVR, upgrading your existing voltage regulation system, or maintaining backup power equipment, the COSIMAT C2.1 delivers the performance, reliability, and precision that AVK is renowned for across the global power generation industry.Key SpecificationsSpecificationValueModel NumberCOSIMAT C2.1ManufacturerAVK (Newage Stamford)Regulation Accuracy±0.5% to ±1.0% (no load to full load)Input Voltage (Sensing)95-480 VAC (single phase)Excitation OutputDC voltage (variable based on load)Operating Frequency50/60 Hz (auto-sensing)Under Frequency ProtectionU/F function with adjustable slopeResponse TimeLess than 100 millisecondsOperating Temperature-40°C to +70°C (-40°F to +158°F)Humidity ToleranceUp to 95% non-condensingMounting TypePanel mount with standard fixing holesDimensions (L
