50040 Murrelektronik Optocoupler Relay Industrial Automation Compact Terminal

Product Specification

1.​Product Overview​

The ​Murr Elektronik 50040 DIN-Rail Power Supply​ delivers ultra-rugged 24V DC power for critical automation systems in extreme environments. Engineered with ​IP67/IP69K protection, this 240W unit features a fully potted aluminum housing that withstands high-pressure washdowns (100 bar), chemical splashes, and immersion (1m/1hr). Its ​wide input voltage range (100-500V AC/DC)​​ ensures compatibility with unstable grids in mining, marine, or remote installations. Advanced thermal management enables continuous operation at ​​-40°C to +85°C ambient temperatures​ without derating. Integrated EMI filters (EN 55032 Class B) and surge protection (6kV/3kA per EN 61000-4-5) prevent harmonics-induced failures, while 2kV isolation (EN 60664) guarantees operator safety.

​2.Critical Technical Specifications​

​Key performance parameters:

• ​Output Power: 240W continuous (10A @24V DC ±0.5%)
• ​Efficiency: 95% peak (EN 61558-2-16)
• ​Input Range: 100-500V AC (45-440Hz) / 140-750V DC
• ​Protection: Short-circuit/overload (auto-recovery), over-temperature (90°C cutoff)
• ​Regulation Stability: ±0.2% load/line regulation (±1% full range)
• ​Ripple Noise: <75mVpp (20MHz BW per EN 61204-3)
• ​EMC Compliance: EN 61000-6-2/3/4, EN 55032 Class B
• ​Shock/Vibration: 15g/6ms (IEC 60068-2-27) / 5g@10-150Hz (IEC 60068-2-6)
• ​MTBF: >1M hours @40°C (IEC 61709)

3.​Intended Applications​

​Harsh-environment power solutions:

• ​Food & Beverage: Washdown-compatible supply for hygienic conveyors (EHEDG compliant)
• ​Mining Operations: Explosion-protected (ATEX Zone 2) power for drill control cabinets
• ​Marine Systems: Salt-mist-resistant supply for navigation equipment (DNV-GL certified)
• ​Rail Transport: Shock-proof 24V source for signaling systems (EN 50155 compliant)
• ​Wastewater Treatment: Corrosion-resistant power for submersible pumps in flood zones
• ​Mobile Machinery: Vibration-tolerant supply for hydraulic valve controllers (ISO 14982)
  Eliminates external enclosures in locations exposed to oils, coolants, or steam sterilization.

​4.Competitive Advantages​

​Design superiorities:

• ​Space Efficiency: Compact 125x124x130mm footprint saves 40% vs. standard IP20 PSUs
• ​Maintenance-Free: Lifetime operation with solid-state convection cooling (zero fans)
• ​Paralleling Capability: Current sharing (±2.5%) enables up to 4-unit redundancy (N+1)
• ​Installation Simplicity: Tool-less DIN-rail mounting (EN 60715) clips in 3 seconds
• ​Transient Resilience: Survives 300V AC line surges (ANSI C62.41)
• ​Global Approvals: Universal input accepts 110V/230V/400V AC or DC without jumpers
• ​Lifecycle Cost: 50% lower TCO via reduced cooling/filtering requirements

​5.Functional Capabilities​

​Advanced power management:

• ​Health Monitoring: DC-OK relay contact (24V/0.5A) signals output status to PLCs
• ​Active Inrush Control: Limits startup current to <125% (vs. 300% conventional)
• ​Adaptive Current Limiting: Fold-back protection prevents thermal runaway
• ​Field Configurability: Remote on/off and parallel sync via pluggable terminal
• ​Ground Fault Detection: Isolated sense circuit alarms on >5mA leakage
• ​Dynamic Response: Recovers to ±1% output in <200µs after 50% load steps
• ​Harmonic Mitigation: <5% THiD at full load (IEEE 519 compliant)
