Category:
Description
Technical Specifications:
  • Rated Power:​ 224 W
  • Input Voltage:​ 90–264 V AC (50/60 Hz) or 130–350 V DC (wide range)
  • Output Voltages:​ +5 V @ 28 A, +12 V @ ~7 A, -12 V @ ~2–3 A (typical multi-rail)
  • Power Factor Correction:​ Active PFC integrated
  • Dimensions:​ 6U height (266.7 mm), 12 HP width, depth ~171.9 mm
  • Backplane Connector:​ H15 male (DIN 41612 compliant)
  • Efficiency:​ >85%
  • Operating Temperature:​ 0°C to +40°C (some sources -20°C to +60°C)
  • Protection:​ Overload, overvoltage, short-circuit
    Functional Features:
  • VMEbus Signal Compatibility:​ Fully compliant with VME power signaling standards including System Fail and Output Voltage OK.
  • Redundancy Support:​ Integrated decoupling diodes for N+1 redundant configurations and passive current sharing.
  • Hot-Swap Capable:​ Designed for live insertion in compatible subracks.
  • Low Ripple:​ Output ripple <10 mVpp for sensitive logic circuits.
    Application Scenarios:​ Industrial automation controllers, aerospace/defense embedded systems, medical imaging equipment backplanes, telecom switches.
    Material & Structure:​ Aluminum heat sink chassis with Eurocard PCB assembly; front panel handle for extraction; forced air cooling via built-in fan.
    Working Principle:​ AC input is rectified, filtered, and switched via high-frequency PWM topology with isolation transformer to generate regulated DC rails; active PFC shapes input current waveform.
    Installation Requirements:​ Plugs directly into 19-inch VME subrack backplane; requires adequate airflow clearance; secure front panel locking levers.
    Precautions:​ Ensure backplane pin alignment before insertion; discharge capacitors if handling removed unit; verify jumper settings for DC input if used in HVDC applications.
