Description
Product Introduction
The GE IS200CPFPG1AAA functions as the Control Power Filter (CPFP) module within the Mark VIe control platform, providing EMI/RFI filtering and surge protection with standard configuration for control power inputs. This module interfaces with the Mark VIe controller via ISBus communication and filters 24 V DC power to I/O modules, protecting them from electrical noise and voltage transients.
The model number breaks down as: IS200 (Mark VIe platform), CPFP (Control Power Filter), G1 (Generation 1), AAA (Standard configuration). The primary differentiator is the combination of EMI/RFI filtering, surge protection, and standard configuration—the CPFP G1AAA provides a reliable, off-the-shelf power filtering solution for turbine and generator applications.

Key Selling Points & Differentiators
- EMI/RFI Filtering: >40 dB attenuation at 100 kHz to 10 MHz—reduces electrical noise from VFDs, motors, and other industrial equipment.
- Surge Protection: 4 kV surge protection (IEC 61000-4-5)—protects control modules from voltage transients and lightning-induced surges.
- Standard Configuration: The AAA variant provides a standard, off-the-shelf configuration—reduces lead time and simplifies ordering.
- Clean Power Delivery: Provides filtered, protected 24 V DC power to I/O modules—reduces the risk of noise-related faults.
- Compact Design: Single module provides both filtering and surge protection—efficient use of cabinet space.
- Full Live Test Certification: Each unit undergoes a 24-hour burn-in with full load testing, filter performance verification, surge protection testing, and ISBus communication testing. We log the MAC ID and calibration data for traceability.
- Direct Drop-In Replacement: Form-fit-function compatible with IS200CPFPG1A and earlier CPFP revisions. Existing wiring and terminal assignments remain unchanged.
- 90-Day Warranty: Includes technical support and cross-ship replacement within 24 hours if the module fails to provide filtering, surge protection fails, or diagnostics report false faults.
Frequently Asked Questions (FAQ)
Q1: What’s the difference between the IS200CPFPG1AAA and the IS200CPFPG1A?
The AAA suffix indicates a standard configuration—the filtering and protection parameters are pre-configured at the factory for typical applications. The G1A is also a standard module but may have different default settings. Functionally, both modules provide the same filtering and surge protection. The AAA variant is typically used for standard power filtering applications. The configuration can be changed in ToolboxST if needed.
Q2: When would I need a CPFP module?
You need a CPFP module when: (1) Your facility has VFDs or large motors that generate electrical noise, (2) You are in an area with lightning or frequent power surges, (3) You are experiencing unexplained I/O faults or communication errors, (4) You want to protect sensitive control modules from power quality issues. The CPFP provides both filtering and surge protection in a single module.
Q3: The CPFP shows a surge event counter increment—what does that mean?
The surge event counter logs each surge event that is clamped by the CPFP’s protection circuit. The counter increments for surges above 500 V. The gas discharge tubes are rated for 20 full 4 kV events. If the counter reaches 15, consider replacing the module. The counter provides forensic data to help identify power quality issues in your facility.
Q4: The CPFP shows a filter health warning—what does that mean?
A filter health warning indicates that the EMI/RFI filter components are degrading. The module monitors the filter performance and reports a warning when attenuation drops below specification. This is typically caused by: (1) Capacitor aging, (2) High ripple current, (3) Sustained overvoltage conditions. Plan to replace the module within 3-6 months. The warning is a pre-fault indicator.
Q5: What’s the maximum current the CPFP can handle?
The CPFP is rated for 5 A continuous. This is sufficient for most Mark VIe cabinets. If you need more than 5 A, use multiple CPFP modules (one per power supply) or a larger filter. The module includes over-temperature protection that will trip if the current exceeds 5 A for more than 10 seconds.
Q6: The CPFP shows an output fault—what could be the cause?
An output fault indicates that the module has detected an issue with the filtered output. Possible causes: (1) The output is shorted—check the wiring and load, (2) Overcurrent—the load is exceeding 5 A, (3) Input voltage out of range—the input is outside 22.8-25.2 V, (4) Internal fault—the module has failed. Access the diagnostic data in ToolboxST to identify the specific condition. Investigate the load and wiring.
Q7: What’s the typical lead time for the IS200CPFPG1AAA, and do you recommend stocking spares?
The IS200CPFPG1AAA is a commonly stocked module—we maintain 8-12 units in inventory. Standard lead time for orders of 1-10 units is 1-2 business days for shipping after QC verification. For critical applications with power quality concerns, we recommend stocking one spare CPFP per cabinet. If you have a fleet of 10+ turbines, a 10% spare ratio is standard practice.
