The Caterpillar VR6 is a heavy-duty, encapsulated Automatic Voltage Regulator designed for high-performance voltage control in brushless generators. It is engineered to maintain a constant output voltage by regulating the DC exciter field power, making it a critical component for stable power generation in 50Hz and 60Hz systems.
Dual-Excitation Support: Compatible with both Shunt (Self-Excited) and PMG (Permanent Magnet Generator) systems.
Precision Control: Maintains a regulation accuracy of ± 0.5% to protect sensitive downstream equipment.
Durability: Fully encapsulated design protects internal electronics against moisture, dust, and heavy engine vibrations.
Advanced Protection: Built-in under-frequency (UFRO) protection and inverse time over-excitation shutdown.
Parallel Ready: Includes a reactive droop compensation feature for seamless operation when paralleling multiple generators.
