An-5-203 Avr Wiring Diagram Pdf _top_ | Fresh ⇒ |

The AN-5-203 (and its variant, the AN-5-203R) is an automatic voltage regulator (AVR) primarily used in Denyo diesel generators. It is a half-wave phase-controlled thyristor type regulator designed for brushless excitation systems. Wiring & Terminal Connections

⚠️ Warning: Always verify with your generator’s service manual. Reversing field wires can cause overvoltage. an-5-203 avr wiring diagram pdf

C. Grounding

• Connect the "Hot" lead (L1) to AVR Terminal 1 (or L).
• Connect the "Neutral" lead (N) to AVR Terminal 2 (or N).
• Note: If your AVR requires 3-phase sensing, you will connect L1, L2, and L3 to terminals 1, 2, and 3 respectively. However, AN-5-203 is usually a 1-phase sensing unit.

Compatibility: For many 13–25 kVA range generators not explicitly listed, this model is often the default AVR. The AN-5-203 (and its variant, the AN-5-203R) is

• Main power winding (U1-U2) – Goes to the load.
• Auxiliary winding (D1-D2) – Feeds terminals 5 & 6.
• Sensing winding (S1-S2) – Comes from the main output terminals.
