Description
GE IC693PWR321 Technical Specifications:
- Input Voltage: 120/240 VAC Auto-select.
- Output Voltages: +5 VDC, +12 VDC, and -12 VDC.
- Output Capacity: High-current +5V output (typically 6A or higher) to support extensive I/O.
- Frequency: 50/60 Hz.
- Hold-up Time: Sufficient to ride through brief power interruptions.
Functional Features:
- High Power Density: Supports full racks of high-draw I/O modules.
- Auto-Select Input: Eliminates the need for manual voltage selection switches.
- Protection: Overcurrent, overvoltage, and short-circuit protection.
- Status LED: Front-panel indicator for power good/fault conditions.
Application Scenarios:
- Main power supply for large Series 90-30 control panels.
- Racks with multiple communication modules, high-density I/O, and motion control cards.
- Industrial environments with standard AC power distribution.
Material Composition & Structural Characteristics:
- Enclosure: Metal-shielded housing for EMI suppression and heat dissipation.
- Cooling: Convection-cooled with internal thermal protection.
- Connectors: Heavy-duty backplane connector and AC input terminals.
Working Principle: AC input is rectified, filtered, and converted to high-frequency AC, which is then transformed and rectified to produce stable +5V, +12V, and -12V DC outputs. Feedback loops continuously regulate the outputs under varying load conditions.
Installation Requirements:
- AC Wiring: Connect 120V or 240V AC to the designated input terminals. Ensure proper grounding.
- Baseplate: Install in the leftmost power supply slot of the Series 90-30 baseplate.
- Ventilation: Provide adequate clearance above and below the module for airflow.
Usage Precautions:
- Load Calculation: Always calculate total backplane current requirements before installation to ensure the PWR321 can handle the load.
- Safety: High voltage AC is present; always lock out/tag out before wiring.
- Fusing: Install appropriate external AC fusing or circuit breaker as specified in the manual.
