KUTAI VOLTAGE REGULATOR Direct Replacement for Basler VR63-4 and VR63-4A Regulator # EA04A

EA04A is a self excited brushless type AVR, which is able to directly replaces Basler VR63-4 and VR63-4A. It can also replace Marathon SE100A.
All manufacturer names and numbers are used for reference purpose only and do not imply that any part is the product of these manufacturer.

Features

• Voltage regulation less than +/-1%
• For use in 50/60 Hz brushless generators
• Optional 120/240 Vac sensing voltage switch *1
• Under frequency and over excitation protection
• EMI suppression
• Built-in high breaking capacity fuse
