This manual describes the operation of the Kutai EA321 Generator Automatic Voltage Regulator
This manual provides instructions for operating and adjusting the Kutai EA321 Automatic Voltage Regulator, designed for use with PMG brushless generators. It details voltage and frequency sensing, soft start, droop control, and protection features including overvoltage, underfrequency, and overexcitation. Adjustment procedures for voltage, stability, and other controls are included, along with safety warnings for proper installation and operation.
The EA321 is compatible with Newage MxX321 generators and includes provisions for external trimmers, analogue inputs, and quadrature droop connections for parallel operation. Environmental and electrical specifications are provided, including operating temperature, humidity, and power input requirements.
| Sensing Input Voltage | 190 — 264 Vac 3 phase |
|---|---|
| Power Input Voltage | 170 — 220 Vac 3 phase 3 wire |
| Excitation Output Voltage | Max. 120 Vdc @ power input 220 Vac |
| Voltage Regulation | Less than +/- 0.5% RMS |
| Operating Temperature | -40 to +70 °C |
| Dimensions | 203.5 (L) x 153.6 (W) x 43.5 (H) mm |
| Weight | 530 g +/- 2% |
Less than +/- 0.5% RMS with 4% engine governing.
From -40 to +70 °C.
Adjust the VOLT control on the AVR board or use an external hand trimmer if fitted.
It allows parallel operation by providing a power factor-dependent signal for voltage droop control.
