2 :::J DESCRPTON: The AVC63-4 model of voltage regulator maintains generator line voltage on brush less generators from 5 KW to over 100 KW in size. The voltage regulator senses generator average voltage to maintain a precise regulation band within ± 1 percent. This is accomplished by converting a 240 V AC single phase power input to a controlled DC signal to the generator's exciter field. The solid-state voltage build-up circuit will enable automatic generator line voltage build-up with a voltage input to the regulator of at least 6 V AC. Customer accessible stability, underfrequency and range adjusts enable fine tuning of the voltage regulator to the generator in use. <( z 0 z u => a.. => 0 a: 0!cc a: w z w CD SPECFCATONS: "CORNER FREQUENCY" --T _-[ -T.-- - The over-excitation feature assists in protecting the voltage regulator during an over-excitation fault condition. During this mode, a shutdown signal is sent to the power stage, turning the regulator off. This feature will reset when the voltage input is removed (less than 6 VAC for a minimum of 2 seconds) to the regulator. Figure 1 demonstrates the underfrequency characteristics of the voltage regulator during prime mover low speed conditions. Customer curve selection matches the voltage regulator to 50 or 60 Hz systems. --n. - J =r FGURE 1 - DC OUTPUT FREQUENCY (Hz) FREQUENCY COMPENSATON CHARACTERSTC MAX FORCNG MAX. 1 MN MN. CONT.
