Automatic Voltage Regulators (AVRs)
With hundreds of thousands in operation, Basler Electric AVRs are amongst the most reliable AVRs in the world.
About the Basler AVR systems
Our Basler microprocessor-based automatic voltage regulators (AVR) are complete excitation systems that include essential features like 0.25% voltage regulation and PID control for enhanced system response.
These AVRs include all of the high end functions of far more expensive excitation systems, such as over/under excitation limiters, VAR/PF control, generator protection, annunciation of generator system conditions, and Modbus™ communications. PulseWidth Modulated power stages help with nonlinear loads, and negative forcing power stages help with power system stability. These devices are the ultimate in functionality, flexibility, and adaptability.
Like for like replacement
Basler Electric’s wide range of Automatic Voltage Regulators and Digital Excitation Control products provides customers with an Excitation System solution for any new generator installation or retrofit application.
One DECS-250 Digital Excitation Control System can accommodate 32Vdc, 63Vdc, or 125Vdc applications up to 15Adc. This unique flexibility provides precision control of virtually any size generators. The DECS-250 also incorporates a pulse width modulated power stage, which improves system performances in non-linear load applications. The DECS-250 is also a like for like replacement of the Basler Electric DECS-200.
