ALSTOM EP3-G-4-A-EN – Integrated Electrostatic Precipitator Controller | EP3 Platform
Engineering Background
The ALSTOM EP3 series represents ALSTOM’s third-generation digital control platform for electrostatic precipitators (ESP), engineered to meet the stringent emission control requirements of power generation, cement, steel, and chemical processing industries. The EP3-G-4-A-EN variant integrates high-voltage energization control, rapper sequencing, and process diagnostics into a single compact module, replacing multi-cabinet legacy systems with a unified DIN-rail-mountable solution.
Product Positioning
Designed for procurement engineers and plant maintenance teams sourcing certified OEM replacement or upgrade modules, the EP3-G-4-A-EN delivers drop-in compatibility with existing ALSTOM ESP installations while supporting modern fieldbus communication and remote SCADA integration. Konmask.com supplies this module from verified industrial channels with full traceability documentation.

Engineering Advantages
- 4-channel integrated design – eliminates inter-module wiring complexity and reduces panel footprint by up to 60% vs. discrete relay-based systems
- Adaptive HV energization – automatic back-corona detection and spark rate optimization for maximum collection efficiency
- Rapper sequence management – configurable rapper timing prevents re-entrainment and maintains collection plate cleanliness
- EN fieldbus compatibility – native integration with plant DCS/SCADA via standard industrial protocols
- Diagnostic & alarm logging – onboard fault memory supports predictive maintenance and root-cause analysis
- OEM-grade reliability – designed and manufactured to ALSTOM EP3 platform specifications for long MTBF in continuous industrial operation
System Architecture & Signal Flow
The EP3-G-4-A-EN operates as the central intelligence node within an ALSTOM ESP control cabinet. The module receives process feedback signals (current, voltage, spark detection) from the high-voltage transformer-rectifier (T/R) sets across all 4 channels. Its onboard DSP executes real-time energization algorithms, issuing firing angle commands to the T/R thyristor controllers. Simultaneously, the rapper control subsystem outputs timed activation signals to electromagnetic or tumbling-type rapper drivers. All operational data is transmitted upstream to the plant DCS via the EN fieldbus interface, enabling centralized monitoring, setpoint adjustment, and alarm management without local panel intervention.

Technical FAQ
Q: Is the EP3-G-4-A-EN a direct replacement for older ALSTOM EP1/EP2 controllers?
A: The EP3 platform uses a different hardware architecture. Direct drop-in replacement depends on your cabinet wiring harness. Contact our team for a compatibility assessment.
Q: What does the “-EN” suffix indicate?
A: The “-EN” suffix designates the European/international standard fieldbus communication variant, as opposed to region-specific protocol variants.
Q: Can this module control both electromagnetic and tumbling rappers?
A: Yes. The rapper control subsystem supports both rapper types via configurable output parameters.
Q: What is the warranty period?
A: Konmask.com provides a 12-month warranty against manufacturing defects from the date of shipment. Extended warranty options are available on request.
Q: Do you provide installation and commissioning support?
A: Yes. Remote technical support and on-site commissioning services are available. Contact us for details.
