Brand New original Kutai AVR made in TaiWan with wholesale price.

 

Hybrid Analog/Digital Single Phase sensing 4 Amp Automatic Voltage Regulator for self-excited (shunt) generators

 

ADVR-440 KUTAI AVR is a direct replacement for Newage Stamford AS440 and also compatible with SX440. It's equipped with Quadrature Droop Input for parallel operation, Over Excitation Protection, Soft Start Voltage Ramping Function, Digital Voltage Sensing and Under Frequency Protection Circuit which effectively reduces the thermal drift.

 

Features for KUTAI ADVR-440 AVR:

Ø  Digital Voltage Sensing and Under Frequency Protection circuits reduce thermal drift

Ø  Soft start voltage ramping

Ø  Over excitation protection

Ø  Quadrature Droop Input for parallel operation

Ø  EMI suppression

Ø  Built-in high capacity fuse
