Digital Excitation Control System (DECS-300)

The microprocessor-based DECS-300 provides precision control for generators of virtually any size and is equally suited for exciter field or main field applications. It provides control signals for pulse width modulated power modules and SCR bridges manufactured by Basler Electric and other manufacturers.

Four customer-selectable control modes:

- Voltage Regulation
- Manual Control (Field Current Regulation)
- VAR Control
- PF Control

Other features include:

Autotracking between operating modes within a single DECS-300 unit
Autotracking between redundant DECS-300 units
Autotransfer to a back-up DECS-300 unit
True RMS sensing, single or three phase
Controls the firing of external bridges by outputting 4-20mA, 0-10Vdc or ±10Vdc
0.25% Voltage Regulation Accuracy
Setup from front panel HMI or by PC with free BESTCOMS Windows®-based setup software
40 standard stability selections
User customizable stability selection
Paralleling compensation from 1 or 5A CTs
