Overview

The KEB 15.F4.182-G438 Power Supply PCB is essential for maintaining the stable operation of the KEB COMBIVERT F4 series drives. Featuring the FA538760 28/04 revision and -G438 option code, this module converts and conditions the power required for the control system, ensuring uninterrupted, clean power for the PLC module and communication interfaces. It isolates the control circuitry from the main power stage, protecting it from voltage spikes and interference, while delivering high efficiency and low heat generation for continuous industrial operation.

Technical Data

Applications

• Precise Speed and Torque Control: Ensures uninterrupted power for real-time motor performance in VFD-controlled systems.

• Integrated Automation Systems: Powers the embedded PLC/DCS and communication interfaces for system-wide data exchange.

• Lift and Hoisting Machinery: Critical for maintaining control logic in safety-sensitive applications, ensuring smooth motion and safe operation.

FAQ

Q1: What is the primary function of this Power Supply PCB?

A1: It converts and conditions power to provide the necessary low-voltage DC supply (e.g., 24 VDC) for the control board, communication interfaces, and digital I/O circuits.

Q2: Why is the -G438 option code present on this Power Supply PCB?

A2: The -G438 option indicates that this board is designed to support control modules with specialized features, such as higher current capacity or advanced motion/communication capabilities.

Q3: If the drive's control panel is dark, is this Power Supply PCB the likely cause?

A3: Yes, a failure of the Power Supply PCB to deliver the required low-voltage DC power (e.g., 24 VDC) can prevent the drive's control panel and status LEDs from illuminating.

Q4: Is this Power Supply PCB interchangeable with other KEB F4 Power Supply PCBs of the same part number but a different revision?

A4: No, revisions (like FA538760 28/04) often reflect component or circuit optimizations. Using a mismatched revision could lead to compatibility issues or damage.
