KUTAI EA448 Generator Automatic Voltage Regulator Operation Manual

About this manual

This document is the Operation Manual for the KUTAI EA448 Generator Automatic Voltage Regulator. It is designed for use with permanent magnet generators, A.R.E.P, or auxiliary winding types, and is compatible with Leroy Somer R448 systems. The manual also notes compatibility with KUTAI IVT-1260 and IVT-2460 add-on modules to boost generator motor starting capacity.

The guide provides detailed specifications for sensing inputs, power requirements, and environmental limits. It includes step-by-step instructions for jumper adjustments (ST1-ST7), potentiometer settings (P1-P5), and wiring configurations for single-phase and three-phase inputs. Diagrams illustrate the outline, power connections, and adjustment layouts.
