DESCRIPTION for AVC63-4 Basler AVR

The Basler AVC63-4 AVR and Basler AVC63-4D voltage regulators maintains generator line voltage no load to full load on brushless generators from 5kW to over 100kW in size.

These voltage regulators sense generator average voltage to sustain a precise regulation band within ±1% throughout the operating temperature range. This is accomplished by converting a 240Vac single phase power input to a controlled DC output signal.

The solid-state voltage build-up circuit allows automatic generator line voltage build-up with as little as 6 Vac residual voltage applied to the regulators input power circuit.

Customer accessible adjustments for stability, underfrequency and the voltage regulation set point are provided to allow the controller to be tuned to the desired performance. The location of these adjustments are different depending on which model is selected. Both, the Basler AVC63-4 AVR and the AVC63-4D are intended to be mounted inside the generators terminal box. For applications that require the voltage regulator adjustments to be made from outside of the terminal box, the AVC63-4D should be considered. On this particular model, the adjustment potentiometers are accessible from the bottom side (label side) of the controller. Holes drilled through the terminal box per Fig. 6 will allow the user to adjust the potentiometers as needed.

For applications that it is necessary to limit access to the adjustment potentiometers, the AVC63-4 would be a suitable selection. This is because the Basler AVR AVC63-4 voltage regulator provides adjustments from the component side of the controller, Fig. 4. When mounted in a generators terminal box, the controllers potentiometers are accessible.

The over-excitation feature assists in protecting the voltage regulator during a prolonged over-excitation condition. During this mode, a shutdown signal is sent to the power stage, turning off the regulator. This feature will reset automatically when the generator voltage drops below 6 Vac for a minimum of 2 seconds.
