The DECS-200-2C is a full-featured microprocessor-based digital excitation control system that integrates control, limiting, and protection functions, suitable for synchronous generators of all sizes. It supports 32Vdc, 63Vdc, and 125Vdc outputs (maximum 15Adc continuous current) and adopts a pulse width modulation (PWM) power stage, which can improve system performance in non-linear load scenarios. It can be set up through the front HMI panel or Windows® configuration software to meet diverse application needs.
DATA SHEET
BASLER DECS200-2C.pdf
- Multi-mode control: Supports Automatic Voltage Regulation (AVR), Field Current Regulation (FCR, manual mode), Var control, and Power Factor (PF) control. Modes can automatically track each other to achieve bumpless transfer.
- High-precision regulation: Voltage regulation accuracy reaches ±0.25% (AVR mode), Var regulation ±2.0%, and power factor regulation ±0.02 pu, ensuring stable operation of the generator.
- Paralleling compensation: Supports reactive droop or cross-current compensation, compatible with 1A/5A current transformers, no need for dedicated CTs, reducing installation costs.
- Comprehensive protection: Includes 8 generator protection functions, such as overvoltage, undervoltage, field overvoltage, field overcurrent, loss of field, loss of field detection, Exciter Diode Monitoring (EDM), and watchdog timer. All protection thresholds and delays are customizable.
- Intelligent limiters:
- Overexcitation Limiting (OEL): Supports online/offline modes, with high/medium/low current levels, with time delay or I²t inverse time characteristics.
- Underexcitation Limiting (UEL): Based on generator ratings, supports built-in curves or 5-point custom curves to prevent loss of synchronism.
- Stator Current Limiter (SCL): With high and low current levels to limit stator overheating.
- Underfrequency compensation or V/Hz limiter: Adjustable slope (0-3.0 pu) and corner frequency (45-65Hz) to adapt to prime mover characteristics.
- Convenient setup: Equipped with a front backlit LCD display and 6 buttons for local setup; can also be remotely configured via Windows® software (including PID selection tool).
- Data recording:
- Sequence of Events Recording (SER): Stores 127 events (with timestamps), recording input/output status changes, system alarms, etc.
- Oscillography: Stores 8 records, each can track 6 variables (such as generator voltage, current, frequency, etc.), with a maximum sampling rate of 600 points/record, supporting COMTRADE format (viewable with BESTWAVE software).
- Remote control: Supports contact input (raise/lower adjustment), analog signals (±10Vdc or 4-20mA), and RS-232/RS-485 communication (Modbus™ protocol) for remote setpoint control.
- Automatic tracking: Supports internal mode tracking (inactive modes follow active modes) and external tracking (dual-machine redundancy, optional), automatically switching to the standby unit in case of failure.
- Soft start function: The voltage build-up rate is adjustable (1-7200 seconds) to reduce voltage overshoot during startup and protect generator insulation.
Wide range of certifications: Certified by UL, CSA, CE, DNV, GOST-R, etc., complying with IEEE C37.90.1-1989 surge withstand and fast transient standards.
- Operating temperature: -40°C to +60°C
- Storage temperature: -40°C to +85°C
- Vibration resistance: 5-26Hz (1.2Gs), 27-52Hz (0.914mm double amplitude), 53-500Hz (5.0Gs)
- Dimensions: 205mm (width) × 171mm (depth) × 304mm (height)
- Weight: 6.35kg
Suitable for excitation control of synchronous generators. It controls the generator's output voltage, reactive power, or power factor by adjusting the excitation current, and is widely used in various scales of power generation systems, including industrial, commercial, and backup power scenarios.
