Description

The DECS-200-2L is a microprocessor-based digital excitation control system designed to precisely regulate the output voltage, vars, or power factor of synchronous generators. It supports various DC excitation applications up to 15 Adc, with outputs of 32Vdc, 63Vdc, and 125Vdc. The system incorporates a pulse width modulated (PWM) power stage, enhancing performance in non-linear load conditions. Suitable for generators of any size, it provides advanced control and protection features.

Features

  • Microprocessor-Based Design: Ensures precise control and flexibility.
  • True RMS Sensing: Supports single or three-phase sensing.
  • High Accuracy: 0.25% voltage regulation accuracy.
  • Stability Settings: 20 preprogrammed PID settings; user-customizable.
  • Protection Functions: Eight generator protection features.
  • Communication Ports: Front panel RS-232, side RS-485 (Modbus™ protocol).
  • Remote Set Point Control: Via contact inputs, ±10Vdc, 4-20mA, RS-232, or RS-485.
  • Underfrequency/V/Hz Ratio Limiter: Adjustable slope and corner frequency.
  • Soft Start Buildup: User-adjustable voltage buildup rate.
  • Paralleling Compensation: Supports reactive droop or differential compensation.
  • Sequence of Events Recording (SER): Logs up to 127 events with timestamps.
  • Oscillography: Records up to 8 oscillographic records.
  • Environmental Compliance: UL, CSA, CE, DNV, GOST-R certified.
  • Operating Temperature: -40°C to +60°C (-40°F to +140°F).
