Product Overview
LIXiSE VR6-K65-12B AVR is encapsulated in a sealed plastic housing, specially customized for Caterpillar 50/60Hz traditional brushless generators. It precisely controls DC excitation power of alternators. The regulation principle is to detect generator output voltage, convert AC voltage into DC signal and compare it with internal reference voltage. The generated error signal adjusts DC excitation output to maintain stable constant generator terminal voltage.
Rich Built-in Functions
- Frequency compensation with adjustable slope
- Inverse time over-excitation shutdown protection
- Integrated solid-state voltage build-up circuit
- Flexible voltage sensing: single-phase or three-phase input
- Multiple power supply options: single/three-phase shunt power or permanent magnet power input
- Parallel droop compensation function for multi-generator parallel operation
- Independent accessory input port, compatible with reactive power and power factor controllers
