EMRI LX20 automatic voltage regulator

The EMRI LX20 is developed for use in brushless generators and accurately controls the output current by controlling the input currant to the exciter. In standard operation, when no safety alerts are triggered then no voltage droop is active, the voltage regulator controls the output current with constant voltage control, regardless of the generator load or frequency. “The AVR is designed as a replacement for the R449, providing optimal flexibility and configurabilityas is reflected by the additional capabilities of the AVR.Nevertheless installation, maintenance and adjustment don’t require special application software.The AVR is protected from the environment by a PUR coating.Mode of control:- Volt per Hertz control- Constant voltage control- Power factor control (PFC)- 0-100% generator current control- 0-100% generator voltage control- Quadrature voltage droop for parallel operation- Current control (Current limiting / Limited motor start)Protection:- Generator phase loss, phase sequence- AVR over temperature- Generator over temperature- Generator over voltage- Generator over current- Generator over excitation- Loss of excitation during PFC- Loss of current sensing during PFC- User adjustable underspeed knee- User adjustable over excitation current- User adjustable generator current limitCommunication:- AVR Status LED- AVR Status contact- CAN busFor more details of this Digital AVR, please download the manual”
