HIMA FPWR01 HIMax Series Dedicated Redundant Safety Power Supply Expansion Module

Product Brief Description

The FPWR01 is a high-performance redundant safety power supply expansion module developed by leading German functional safety automation manufacturer HIMA, belonging to the HIMax series Safety Instrumented System (SIS) dedicated power product line. As an extension accessory specially designed for HIMax series safety systems to realize multi-redundant power supply architecture expansion, it is specially designed for ultra-large-scale high-risk industrial scenarios that have extremely strict requirements for power supply reliability, further enhancing the fault-tolerant capability of the system power supply link, ensuring that the safety system will not experience unexpected power interruption even when multiple independent power supply units fail at the same time, providing the most stable and reliable power guarantee for the long-cycle uninterrupted operation of the large-scale safety control system.

Core Technical Specifications

• Manufacturer: HIMA Paul Hildebrandt GmbH, original German industrial functional safety grade production standard
• Product Category: HIMax series dedicated safety power supply redundant expansion module, model FPWR01
• Physical Parameters: DIN rail modular design, net weight about 0.6kg, IP20 protection grade, fully compliant with industrial anti-vibration and anti-electromagnetic interference standards
• Electrical Parameters: 24V DC rated operating voltage, supporting up to 3 independent safety power supply units for parallel redundant operation, maximum output current 20A, internal integrated high-efficiency current sharing circuit

• Redundancy Expansion Capability: After using FPWR01, the HIMax system can support up to N+1 and N+2 multi-redundant power supply architecture, which can tolerate up to 2 independent power supply unit failures without any disturbance
• Protection Mechanism: Built-in overcurrent, overvoltage and reverse connection protection functions, which can effectively protect the rear-end safety control modules from damage caused by abnormal power supply faults
• Operating Environment: -20°C to +60°C working temperature range, 0-95% non-condensing relative humidity, fully meeting industrial EMC anti-interference certification standards

Key Core Functions

• Multi-Power Parallel Current Sharing Redundancy: The module integrates a high-precision active current sharing circuit, which can accurately distribute the load current to each parallel safety power supply unit, avoid the overload damage of a single power supply unit caused by uneven load distribution, greatly improve the overall service life and operational reliability of the system power supply group
• Full Fault Isolation Capability: The module has built-in independent high-speed fault isolation unit, once any power supply unit in the parallel power supply group fails, it will automatically and quickly isolate the faulty power supply unit within 5ms, which will not cause any impact on the normal operation of other power supply units and the rear-end safety system
• Real-Time Power Health Monitoring: The module can monitor the operation status and load rate of each parallel power supply unit in real time, and upload all power supply health data to the HIMA SILworX engineering system, helping maintenance personnel grasp the health status of the entire system power supply group in real time, find potential power supply faults in advance
• High-Density Space-Saving Design: The ultra-compact DIN rail installation design greatly reduces the installation space occupation of the redundant power supply group, effectively saving the internal space of the safety control cabinet, and reducing the overall cost of the system power distribution design
• Live Hot-Swap Support: The module supports live hot-swap operation under normal system operation, maintenance personnel can directly replace the faulty power supply module or add parallel power supply units without interrupting the normal operation of the safety control system, which greatly improves the system maintenance efficiency

Typical Application Scenarios

• Large-scale petrochemical complex: 10 million tons level refinery full-plant emergency shutdown system (ESD) that requires ultra-high power supply availability, supporting N+2 power supply redundant architecture
• Power industry: Heavy-duty gas turbine and supercritical steam turbine unit safety protection system, which cannot tolerate any power supply interruption fault
• Oil & gas industry: Offshore oil platform production safety control system, which cannot carry out power supply system maintenance at will in the offshore special environment
• Ultra-large coal chemical project: Full-plant safety interlock control system, supporting 4-6 years of ultra-long cycle non-stop operation, no regular power supply planned maintenance is required

Installation and Maintenance Guidelines

• Strictly implement anti-static protection before installation: operators must wear reliably grounded anti-static wrist straps to avoid static electricity damaging the precision current sharing circuit components inside the module
• The power supply wiring must strictly follow the industrial safety power distribution specifications, use dedicated safety power cables, and the grounding must be reliable, to avoid power supply abnormalities caused by poor grounding
• After installation, perform full redundant power supply performance test through the dedicated HIMA SILworX engineering software, confirm that the parallel current sharing function, fault isolation function and status monitoring function of the power supply expansion module fully meet the design requirements
• Regularly check the status indicator on the module surface during daily operation, and clean the dust accumulated on the module surface every 2 years, which can effectively extend the service life of this safety power supply expansion module to more than 15 years
