This guide assumes you have a generic, brush-type AVR with the specific terminal configuration often associated with this part number.
The AN-5-203 AVR wiring diagram PDF is a detailed document that illustrates the electrical connections of the device. The diagram typically includes:
The is compatible with the following Denyo generator models:
Secure the AVR inside the generator terminal box. Use anti-vibration mounts if available, as constant shaking can loosen the internal components of the AVR. an-5-203 avr wiring diagram pdf
Adjusts the damping of the voltage response to prevent hunting or oscillation.
AN-5-203 AVR Wiring Diagram PDF: Comprehensive Installation and Guide The
Start the engine and adjust the "VOLT" potentiometer on the AVR to achieve the desired output voltage (e.g., 220V/380V or 110V/220V). This guide assumes you have a generic, brush-type
These usually connect to the auxiliary winding of the generator. If your generator doesn’t have an auxiliary winding, these are sometimes jumped from the sensing lines (depending on the specific model variation). 3. Exciter Output (Field Control)
| Terminal | Function | Typical Wire Color | |----------|----------|--------------------| | 1 & 2 | AC input (sensing) – 120/220V | Red / Black | | 3 & 4 | Field output (to exciter stator) | Blue / Yellow | | F1 / F2 | Shunt field (sometimes labeled S1/S2) | Orange / White | | U / V / W| Auxiliary winding input (for start‑up) | Green / Brown / Gray |
The AN-5-203 AVR Wiring Diagram PDF is recommended for: Use anti-vibration mounts if available, as constant shaking
The AN-5-203 AVR is designed to maintain a stable output voltage from brushless generators by regulating the exciter field current. It is primarily utilized in smaller to mid-sized Denyo DCA-series generators, such as the 13ESK, 15ESK, 25ESI, 25ESK, 25SPI, and 25SPK models.
⚠️ Terminal naming may vary slightly between manufacturers. Always verify the markings on your specific AVR unit before making connections.
