Rectifier Utility data screen
This screen refers to the AC source supplying the Rectifier.
This screen displays:
• Iout1 = output current Rectifier Bridge.
• Iout2 = output current 2
nd
Rectifier Bridge (optional 12 pulse Rectifiers only).
• The voltage levels between the three phases (line-to-line).
• The input frequency of the Rectifier.
