GE 8913-PS-AC Power Supply Module
1. Product Description
The GE 8913-PS-AC is a high-reliability dual-output power supply module designed for industrial automation systems, including DCS (Distributed Control Systems) and PLC (Programmable Logic Controller) applications. Engineered for GE Fanuc’s PAC8000 series, the 8913-PS-AC delivers 12V/5A and 24V/5A DC power from a universal AC input (85–264 VAC), ensuring stable operation in harsh environments. With a compact DIN-rail mount design (27.8 x 21.4 x 2.5 cm) and extreme temperature compatibility (-40°C to 70°C), it withstands dust, vibration, and hazardous conditions (C1D2 certified). Key features include overvoltage/overcurrent protection, 87% efficiency, and seamless integration with GE’s Genius I/O and 90-30 PLC systems. Ideal for industries like oil & gas, power generation, and water treatment, the module ensures continuous operation in critical infrastructure.

3. Advantages and Features
- Dual Isolated Outputs: Simultaneous 12V/5A and 24V/5A power for mixed voltage systems (e.g., control logic + field devices).
- Extreme Environment Resilience: Operates in -40°C to 70°C with 93% humidity tolerance, suitable for outdoor/hazardous locations (C1D2 certified).
- Power Factor Correction (PFC): Low harmonic distortion (IEC 61000-3-2 compliant) and negligible inrush current.
- Safety Mechanisms: Dual-loop overvoltage protection, short-circuit recovery, and thermal shutdown for system reliability.
- Case Study: A petrochemical plant reduced downtime by 20% using the 8913-PS-AC in a SIL 2-rated safety system, leveraging its C1D2 certification and surge immunity.
4. Application Areas and Use Cases
- Industries: Oil & gas (refineries, pipelines), power generation, water/wastewater treatment, chemical processing.
- Scenarios: DCS/PLC power supply, fire & gas safety systems (FB-8800 compatible), hazardous location equipment (Zone 2/Div 2).
- Use Case: A wastewater treatment facility deployed the 8913-PS-AC to power a GE Genius I/O system in a corrosive, high-temperature environment. The module’s dual outputs and -40°C to 70°C range ensured 4+ years of failure-free operation.

6. Selection Recommendations
- Voltage Needs: Verify 12V/24V DC load requirements (total ≤10A).
- Environment: Choose the 8913-PS-AC for extreme temperatures, hazardous zones, or high vibration (use optional heavy-duty DIN rail kit).
- Redundancy: Output 2 supports load sharing (external diode required for Output 1 redundancy).
- Space: Compact design fits in small panels; confirm DIN rail compatibility (35 mm x 7.5 mm T-section).
7. Precautions
- Installation: Mount vertically for cooling; torque terminals to 0.5–0.7 N·m. Use 16–22 AWG wires (shielded for EMC compliance).
- Start-Up: Allow 30 seconds for voltage stabilization; ensure proper grounding (earth terminal provided).
- Maintenance: Inspect terminals annually; replace if exposed to liquids. Clean dust with compressed air (non-conductive).
- Safety: Disconnect power for 30 seconds before servicing (capacitors retain charge). Avoid parallel operation without manufacturer approval.
