IS200CPFPG1A

The IS200CPFPG1A is a Control Power Flash Protect (CPFP) board developed by General Electric, designed for the Innovation Series medium voltage AC drive systems. This board serves as a protective power distributor and monitor for the 48 V AC power bus, providing isolated control power to bridge interface boards and monitoring critical system parameters.

Features

• Control Power Distribution: Distributes control power within the AC drive system, ensuring safe and isolated delivery to bridge interface boards. This facilitates the reliable operation of the drive system.
• Safeguarding Power Bus: Protects the 48-volt power bus from faults or abnormalities, enhancing the safety and reliability of power distribution.
• Monitoring Input Line Fuses: Continuously checks the status of input line fuses, detecting faults or failures promptly to allow for timely intervention and maintenance.
• Insulation Failure Monitoring: Monitors insulation failure of source power cables to identify issues and prevent potential hazards or malfunctions.
• Mounting and Placement: Typically mounted on an insulated panel inside the drive's high-power section, ensuring effective protection and control.
• Input and Output Connectors: Features two 3-pin input connectors and seven 3-pin output connectors for power distribution. These connectors ensure secure and reliable power transmission.
• Fuse Installation: Includes three small fuses (FU1, FU2, FU3) with ratings of 125 volts or 250 volts to protect against excessive currents or faults.
• Jack Connector Ports: Eleven jack connector ports around the edges of the board enable connection to various external devices or components.

Product Attributes

• Voltage Spike and Transient Protection: Provides protection against voltage spikes and transients, reducing the risk of damage or system failure caused by electrical disturbances.
• Damage Prevention and System Reliability: Diverts excess voltage away from sensitive components to prevent damage and maintain system reliability, crucial in high-stakes applications.
• Flash Memory for System Configuration and Setup Data: Incorporates flash memory for storing critical system configuration and setup data, ensuring retention even during power outages.
• Reprogrammable Data for Flexibility and Upgrades: Allows for reprogramming of system data to enable easy upgrades and modifications without hardware changes.
• Enhanced System Maintenance and Troubleshooting: Facilitates maintenance and troubleshooting by storing configuration data, allowing quick restoration and efficient problem-solving.

I/O Isolation and Distribution

• The 48 V AC, 27 kHz control power supply is fed into the module, with an onboard high-voltage transformer (T8) providing 8000 V rms dielectric isolation.
• The transformer’s secondary feeds the output circuits, which are fuse-protected and shielded to chassis ground. Surge protectors are installed across the output power connectors.

Distributed Control System

• External communication links to the plant's distributed control system (DCS) provide real-time Mark VIe data and allow sending discrete and analog commands.
• Connections include:
  • Serial Modbus Slave connection via RS-232C port or dedicated gateway controller.
  • High-speed Ethernet link at 100 Mbaud using Modbus Slave over TCP/IP protocol.
  • High-speed Ethernet link at 100 Mbaud using TCP/IP protocol with GEDS Standard Messages (GSM), enabling advanced integration and functionality.

CPFP Isolation Lost Trip Fault

• This fault indicates a potential compromise in the isolation within the CPFP power supply isolation card, which is crucial for isolating phases and the control system.
• Symptoms include a failure of the status light transmitted via fiber. To troubleshoot:
  • Inspect Fiber Connection: Ensure correct installation and check for light transmission between CPFP and FOSA.
  • Check for Light Transmission: If light is visible, the issue may lie with FOSA or BICM, requiring further investigation.
