DAVR-90 is a “microcontroller based, state-of-the-art design, specifically engineered for high-performance demanding applications for large capacity generator systems. This AVR is designed with complex applications in mind and gives extensive freedom to the OEM to fulfil customer requirements by configuring the AVR parameters, using PC Tools SW package.
• Microprocessor based design for high-performance,
• Continuous Excitation drive capability, in excess of 5Adc, 140% overload capacity for 120 sec., 200% for 10 seconds,
• Integrated BLM® function control to improve BLOCK-LOAD handling capability of the generator,
• 3-Phase TRUE RMS sense voltage measurement for precise voltage regulation in high-harmonic distorted load conditions,
• SHUNT and AUX and PMG connection modes for power input to AVR,
• AUXILIARY analogue inputs for external control of AVR functions,
• 2xPt100 temperature sensing input for alternator winding safety.
• Excellent stability control through digital signal processing,
• “LINE” compensation or “DROOP” compensation by parameter configuration setting,
• ALARM relay output for external safety sequence control of the generator,
• Galvanically isolated USB communication port for AVR parameter configuration and operation monitoring,
• Secure fast-on terminals for power connections,
• Encapsulated construction for extreme environmental operating conditions,
• Construction is resistant to high vibration mounting,
• CE compliant for EMC emissions,
• UL compliant safety standards
