DESCRIPTION of Basler BE350 Voltage Regulator:

The Basler Generator AVR BE350 maintains generator line voltage no load to full load on brushless generators from 5kW to over 100kW in size. This voltage regulator senses 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 low as 10 Vac residual voltage applied to the regulator's 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 BE350 is intended to be mounted inside the generator's terminal box. The BE350 has adjustment potentiometers that are accessible from the bottom side (label side) of the controller. Holes drilled through the terminal box (per Fig. 6) allow the user to adjust the potentiometers as needed.

Figures 1a and 1b demonstrate 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.
