Description
GE IC695PSD140A Technical Specifications:
- Input Voltage: 24 VDC nominal.
- Output Power: 140 Watts total.
- Slot Occupancy: Two (2) slots.
- Output Current: Significantly higher current capacity on 3.3V and 5.1V rails to support dense I/O configurations.
Functional Features:
- High Power Density: Delivers up to 140W in a standard 2-slot form factor.
- Advanced Thermal Management: Enhanced internal heat sinking and fanless convection cooling design.
- Comprehensive Protection: Over-voltage, over-temperature, and over-load protection with automatic shutdown and recovery.
- Diagnostic LEDs: Full 4-LED status indication panel.
Application Scenarios:
- Large-scale process control systems with dozens of analog and discrete I/O modules.
- Motion control racks driving multiple servo drives via the backplane.
- Systems utilizing high-performance CPUs (e.g., CPU320) alongside communication-heavy modules like PNC001.
Performance Parameters:
- Load Capacity: Capable of powering fully populated RX3i racks without requiring additional expansion power supplies.
- Efficiency: High-efficiency DC-DC topology minimizing thermal output at full load.
Material Composition & Structural Characteristics:
- Thermal Design: Features larger internal heat sinks and optimized PCB copper pours for thermal dissipation.
- Enclosure: Ruggedized 2-slot housing with enhanced ventilation channels.
Working Principle: Utilizes advanced synchronous rectification and high-frequency switching to efficiently convert 24VDC to the required backplane voltages at high current levels, while maintaining tight voltage regulation under dynamic load changes.
Installation Requirements:
- Power Budgeting: Always calculate the total backplane power consumption before installation to ensure the 140W capacity is not exceeded.
- Input Wiring: Requires heavier gauge DC input wiring compared to the 40W models due to higher current draw from the 24V source.
Usage Precautions:
- Non-Redundant: Like other RX3i power supplies, this module does not support parallel redundancy.
- Thermal Clearances: Ensure adequate top and bottom clearance in the enclosure for natural convection cooling.
- Inrush Current: Account for inrush current when sizing the upstream 24VDC power supply and circuit breakers.
