DAVR-40 is a “microcontroller integrated voltage regulator unit”, designed for high performance, with generators operating into dynamically complex loads. This AVR model offers high-performance operation with relatively low cost, by utilising an SCR controlled power stage for excitation of the alternator. It can deliver continuous 5.0Adc excitation power into the FIELD winding and can handle 130% overload for a minimum duration of 120 seconds.
• Microprocessor based design for high-performance,
• Continuous Excitation drive capability, in excess of 5Adc, 130% overload capacity for 120 sec.,
• Integrated BLM® function control to improve BLOCK-LOAD handling capability of the generator,
• TRUE RMS sense voltage measurement for precise voltage regulation in high-harmonic distorted load conditions,
• SHUNT and AUX connection modes for power input to AVR,,
• AUXILIARY analogue inputs for external control of AVR functions,
• EXT 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, • USB communication port for AVR parameter configuration,
• 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,
