Description

Foxboro P0922YU Technical Specifications:

  • Input Voltage: 100-240V AC, 50/60Hz (Universal input).
  • Output Voltage: Regulated 24 VDC (and/or 5 VDC for logic).
  • Output Current: High-capacity output to support fully loaded racks.
  • Redundancy: Supports parallel operation for N+1 redundancy.

Functional Features:

  • Power Conditioning: Filters out line noise, transients, and voltage sags.
  • Protection: Over-voltage, over-current, and short-circuit protection.
  • Status Monitoring: Reports power good/fail status to the controller.
  • Hot-Swappable: Allows replacement without shutting down the system (in redundant configs).

Application Scenarios:

  • Primary power source for I/A Series control cabinets.
  • Redundant power systems in critical infrastructure.
  • Retrofit projects upgrading legacy power supplies.

Performance Parameters:

  • Efficiency: > 90% high-efficiency switching topology.
  • Ripple & Noise: < 50 mV peak-to-peak.
  • Hold-up Time: > 20 ms at full load.

Material Composition & Structural Characteristics:

  • Enclosure: Metal chassis for EMI shielding and heat dissipation.
  • Cooling: Convection-cooled with internal heat sinks.
  • Connectors: Heavy-duty power input and backplane output connectors.

Working Principle: AC input is rectified and filtered, then switched at high frequency by power MOSFETs. A high-frequency transformer provides isolation and steps down the voltage. The output is rectified, filtered, and regulated by a feedback loop to maintain precise voltage despite load or line variations.

Installation Requirements:

  • Ventilation: Ensure adequate clearance for airflow.
  • Wiring: Use appropriately sized conductors for input and output.
  • Grounding: Connect chassis ground securely.
  • Fusing: Install external input fusing as specified.

Usage Precautions:

  • Capacitor Discharge: Wait at least 5 minutes after power-off before servicing to allow capacitors to discharge.
  • Load Balancing: Distribute I/O modules evenly across redundant power supplies.
  • Replacement: Use identical or approved equivalent power supplies.
