Electric Power Generation Installation and maintenance 5384 en - 2022.02 / j R150 AVR 1 - GENERAL DESCRIPTION The R150 automatic voltage regulator (AVR) is a compact, high-performance encapsulated unit. It incorporates the latest technology and efficient components to achieve a high degree of miniaturisation when applied to a 3-phase and 1-phase AC brushless generator, within its input and output limits. The unit offers excellent reliability.
Electric Power Generation Installation and maintenance 5384 en - 2022.02 / j R150 AVR 3 - TECHNICAL SPECIFICATION 1) Sensing input - Voltage: 240 VAC ± 10% for 1-phase, 380 V to 480 VAC ± 10% for 3-phase, 2-line sensing. The AVR senses the true average of the line-to-line waveform. Use the resistor (SMD) network for trouble-free sensing and control of sensed voltage/regulation.
Installation and maintenance Electric Power Generation 5384 en - 2022.02 / j R150 AVR 4 - MAIN FUNCTION OF THE AVR The AVR is powered by the line-to-neutral terminals of the AC generator with 240 VAC at 50/60 Hz. The regulated sensing voltage is based on the generator line-to-line terminals.

Electric Power Generation Installation and maintenance 5384 en - 2022.02 / j R150 AVR 5 - AVR SETTINGS 5.1 - V-TRIM (V) 5.3 - STAB (S) This function is provided for setting the voltage up to ± 12% of rated voltage by means of a potentiometer. Turn the potentiometer clockwise to increase the voltage and vice versa, once the rated speed has been reached. It is also possible to connect an external potentiometer. 5.

Electric Power Generation Installation and maintenance 5384 en - 2022.02 / j R150 AVR 8 - MULTIMETER CHECKS Equipment: Digital multimeter. Select Diode mode on the digital multimeter. The resistance between F1 and F2 (with the multimeter jack common applied to F1 of the AVR) should be between 0.4 and 0.6 V, and vice versa (with the multimeter jack common applied to F2 of the AVR) should give INFINITY.
