In this article, we will give you a brief overview of the Basler Electric Voltage Regulator KR4F, its features and specifications, and where to find the wiring diagram PDF online. We will also provide some tips and tricks on how to use and maintain your voltage regulator properly. So, let's get started!


What is the Basler Electric Voltage Regulator KR4F?




The Basler Electric Voltage Regulator KR4F is a device that precisely controls the output voltage of an AC electric generating system by controlling the amount of current supplied to the exciter (or generator) field. It is designed to be compatible with any of the following accessories and equipment:


  • VAR/Power Factor Controller (SCP 250)



  • Series Boost Option



  • Current Transformers (CT2 through CT50)



  • Minimum/Maximum Excitation Limiter (EL 200)



  • Auto-Synchronizer (BE3-25A or BE1-25A)



The Basler Electric Voltage Regulator KR4F has built-in Electromagnetic Interference (EMI) filtering and an underfrequency roll-off characteristic. It also has a variable frequency compensation that can be selected as either V/Hz or 2 V/Hz.


What are the Features and Specifications of the Basler Electric Voltage Regulator KR4F?




The Basler Electric Voltage Regulator KR4F has the following features and specifications:
