The VR6 is a high-performance automatic voltage regulator designed for Caterpillar generator sets. It continuously monitors the generator’s output and regulates the exciter field to maintain a stable voltage, even when load conditions change.

? Key Features

• Supports wide voltage input/sensing ranges (e.g., 180-280 V AC single- or three-phase for shunt-excited, or 63-105 V AC three-phase for PMG input).

• Output capability of approximately 12 A DC at ~65 V DC in normal operation; higher levels possible for short forcing mode.

• High regulation accuracy (around ±0.5% typical) across load changes.

• Built-in features for frequency compensation, droop for paralleling, sensing flexibility (single-phase or three-phase), and protection against over-excitation.

• Rugged design suited for industrial and standby generator environments (operating temperature range down to around -40 °C and up to around +70 °C).
