EA04A
Generator Automatic Voltage Regulator 64 VDC 4 Amp
EA04A self excited brushless type genset voltage regulator is a compatible replacement for Basler VR63-4 and VR63-4A regulator.
*All manufacturer names, numbers, symbols and descriptions are used for reference purpose only and do not imply that any part is the product of these manufacturer.
Features
- Voltage Regulation < ±1%
- For Use In 50/60 Hz Brushless Generators
- Optional 120/240 VAC Sensing Voltage Switch
- Under Frequency & Over Excitation Protection
- EMI Suppression
- Built-in High Breaking Capacity Fuse*
*Basler Model VR63-4A only fits 120 VAC Generators, and Basler Model VR63-4 only fits 240 VAC Generators respectively, and both original Basler models do not have fuse protection.
