GHFC Baureihe

The GHFC series has been developed for applications where reliable DC power supply must be maintained even in the event of a failure of the general mains supply. Typical applications include power generation and distribution facilities, transportation infrastructure, and industrial process and production environments. The systems provide power to control, monitoring, measurement, regulation and data processing equipment, supporting continuity of critical operational processes.

The high-frequency switched-mode architecture combines operational reliability with a compact system design. Active load sharing and integrated active decoupling from the DC bus support stable system performance. Rectifier modules can be replaced or expanded during operation, allowing the system to adapt flexibly to changing requirements without interrupting operation.

The integrated GMU monitoring unit provides clear visualization of operating values and status information via a backlit LCD display. Additional monitoring and signaling functions can be added through the internal communication bus. Event logging, battery supervision and comprehensive diagnostic functions support transparent system monitoring and simplify maintenance procedures. Integration into existing control and supervisory systems makes the GHFC series a versatile solution for modern DC power supply installations.

• battery-backed architecture enables continued operation of critical loads during mains failures
• hot-plug technology simplifies system expansion and service activities during operation
• active load sharing ensures balanced utilization of rectifier modules
• modular monitoring functions support project-specific system customization
• integration into existing control systems reduces modernization effort
• automatic self-configuration via the internal bus simplifies commissioning of additional modules
• advanced diagnostic functions support rapid fault analysis
• n+1 redundancy concepts support high system availability
• event logging simplifies documentation and maintenance planning

The GHFC series supports the planning of centralized DC power supply systems for industrial, utility and transportation infrastructure projects. Multiple voltage ranges and the possibility of operating rectifier modules in parallel allow the system to be adapted to a wide variety of project sizes. The modular architecture also simplifies consideration of future expansion requirements during the planning phase.

For planners, additional benefits arise from the ability to integrate monitoring, signaling and diagnostic functions within a single platform. Integration into existing supervisory systems supports incorporation into established infrastructures while providing long-term investment security.

The GHFC series has been designed for efficient installation and long-term serviceability. Hot-plug module technology allows rectifier modules to be replaced or expanded without major modifications. Automatic self-configuration of new components via the internal communication bus significantly reduces the effort required for future expansions.

The intuitive operating and display terminal supports commissioning, diagnostics and service directly on site. Extensive monitoring functions, event logging and optional expansion modules enable project-specific adaptation to individual applications. This supports efficient maintenance procedures and helps minimize downtime.
