HIMA PS1000WR011 HIMax Series 24V DC Redundant Safety Power Supply Module

Product Brief Description

The PS1000WR011 is a high-reliability redundant safety power supply module developed by leading German functional safety automation manufacturer HIMA, belonging to the HIMax series Safety Instrumented System (SIS) dedicated power supply product line. As the core stable power supply component of the HIMA HIMax safety control system, it is specially designed for high-risk industrial scenarios such as petrochemical, power, oil & gas and other industries that have extremely strict requirements for power supply reliability, providing continuous and stable 24V DC power supply for all safety control modules in the system, ensuring that the safety system will not experience unexpected power interruption during long-term operation, and providing the most fundamental power guarantee for the stable operation of the entire safety instrument system.

Core Technical Specifications

• Manufacturer: HIMA Paul Hildebrandt GmbH, original German industrial functional safety grade production standard
• Product Category: HIMax series dedicated redundant safety power supply module, model PS1000WR011
• Physical Parameters: DIN rail modular design, compact industrial metal shell, net weight about 0.9kg, IP20 protection grade, fully compliant with industrial anti-vibration and anti-electromagnetic interference standards
• Electrical Parameters: Wide-range AC input 100-240V, 50/60Hz; rated output 24V DC, maximum output current 10A, maximum output power 240W; built-in active power factor correction (PFC) and surge current regulation function
• Safety Performance: Passed TÜV IEC 61508 SIL3 functional safety certification, system power supply fault diagnostic coverage rate up to 99.99%, mean time between failures (MTBF) as high as 2.52 million hours
• Redundant Design: Natively supporting dual redundant power supply parallel operation, no single point of failure in the whole power supply link, the system power supply availability is as high as 99.999%
• Protection Mechanism: Output works according to UI characteristic curve, automatically switches to safe hiccup mode when overload or short circuit occurs, effectively protecting the rear-end safety modules from damage
• 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

• Ultra-High Efficiency Energy Saving Performance: Adopting advanced industrial-grade power conversion circuit design, the maximum conversion efficiency is as high as 95.2%, which greatly reduces the heat generation inside the module, not only reduces the energy consumption of the system, but also effectively extends the service life of the power supply and the rear-end safety modules, reducing the long-term operation and maintenance cost of the system
• Full Redundant Fault-Tolerant Architecture: The module supports dual redundant parallel operation mode, when one power supply module fails or the input power is interrupted, the other backup power supply can complete non-disturbing switching within 10ms, completely ensuring that the safety system will not experience power interruption, avoiding the huge safety risk and economic loss caused by the unexpected shutdown of the safety instrument system
• Full Self-Diagnostic and Status Monitoring: Built-in independent power supply health monitoring function, with DC-OK status indicator and passive relay contact, which can real-time monitor the output voltage status, and upload the power supply operation data to the HIMA SILworX engineering system, helping maintenance personnel grasp the health status of the power supply in real time, and find potential power supply faults in advance
• Highly Compact Space-Saving Design: The module adopts ultra-compact DIN rail installation design, the width is only 49mm, which can make full use of the limited installation space in the control cabinet, effectively saving the overall space occupation of the safety system, and reducing the volume and cost of the control cabinet
• Overload and Short Circuit Safety Protection: The output adopts UI characteristic curve working mode, when the rear-end load has overload or short circuit fault, it will automatically switch to safe hiccup protection mode, which can not only effectively protect the power supply itself from damage, but also avoid the impact of fault current on the rear-end expensive safety control modules, ensuring the absolute safety of the entire system hardware

Typical Application Scenarios

• Petrochemical industry: Stable power supply for refinery emergency shutdown system (ESD), burner management system (BMS) and fire and gas detection system (F&G)
• Power industry: Reliable power supply for gas turbine and steam turbine safety protection systems in thermal power plants, and safety power supply for new energy power generation grid-connected safety control systems
• Oil & gas industry: Continuous power supply for large centrifugal compressor anti-surge safety systems of natural gas long-distance transmission trunk lines and LNG receiving station process safety systems
• Metallurgical industry: Stable power supply for large blast furnace and rolling mill safety interlock control systems in steel plants

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 power conversion components inside the module
• The input power wiring must strictly follow the industrial safety power distribution specifications, use dedicated power cables that meet the safety level, and the grounding must be reliable, to avoid power supply abnormalities caused by poor grounding
• After installation, perform full power supply performance test through the dedicated HIMA SILworX engineering software, confirm that the output voltage stability, redundant switching function and fault protection function of the power supply fully meet the design requirements
• Regularly check the DC-OK 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 module to more than 15 years
