Description
1. At-A-Glance Executive Brief
- Model: 3BHE036163R6206
- Brand: ABB
- Part Type: Excitation System Control / Regulator Board
- Lifecycle Status: Active / Mature Support Tier
- System Compatibility: ABB UNITROL Power Generation & Excitation Control Platforms
- Firmware Note: Requires matching revision configuration for proper AVR node synchronization
2. Technical Introduction
Unexpected voltage regulator failure on synchronous generators forces plant operators to scramble for exact hardware matches to prevent prolonged grid disconnection.
The ABB 3BHE036163R6206 acts as a critical processor and signal-handling component within industrial excitation architectures. It processes closed-loop feedback parameters, manages field current regulation, and coordinates high-speed gate signals to maintain stable terminal voltage across variable electrical loads.
- Best Suited For:
- Hydroelectric and thermal power plant generator retrofits
- Industrial captive power station voltage stability maintenance
- Direct drop-in hardware replacement in legacy UNITROL node racks
3. Core Technical Specifications
Please refer to the OEM datasheet for complete environmental tolerances and electrical ratings.
- Module Function: Excitation Control and Regulation Assembly
- Mounting Style: Rack-mounted internal system card
- Interface Protocol: Proprietary ABB internal system bus
- Operating Environment: Designed for industrial switchgear and control cabinet installations
4. Field Engineer’s Tech Notes
- Firmware Version Matching: Ensure the replacement board matches the exact revision code of adjacent modules in the rack. Mismatched firmware versions across internal communication nodes can trigger continuous watchdog failures or inhibit automatic voltage regulation (AVR) handshakes.
- EEPROM / Parameter Backup: Always pull a complete configuration backup via the service software before hot-swapping or replacing this board. Failing to re-upload site-specific tuning parameters will result in uncalibrated field excitation limits during initial startup.
5. Adaptive QA & Testing Protocol
Each unit undergoes automated functional bench testing on specialized ABB excitation test rigs to verify internal microprocessor health, memory integrity, and logic channel response times. Signal conditioning paths for voltage and current feedback inputs are verified using precision calibrators. Comprehensive test logs and pre-dispatch inspection videos are available upon request to ensure full operational confidence.
6. Buyer’s FAQ
- Are these units supplied as new surplus or refurbished?We maintain inventory in both factory-sealed New Surplus (NSFP) and rigorously bench-tested refurbished conditions, backed by a standard operational warranty.
- What is the standard delivery timeframe for urgent orders?Emergency orders process within one business day with priority global shipping options available to curtail costly plant downtime.
- Is this exact catalog number directly interchangeable across different revisions?Suffix revisions must be verified against your system’s bill of materials and software version to guarantee physical slot and communication compatibility.
