1. Basic Information

• Manufacturer: Triconex (a brand under Schneider Electric).
• Product Type: Redundant DC power supply module.
• Primary Function: Provides regulated, fault-tolerant DC power to Triconex safety system chassis (e.g., Tricon, Trident) and associated I/O modules, ensuring continuous operation of safety-critical equipment.
• Compatibility: Fully integrated with Triconex Tricon V11/V12 and Trident safety controllers, supporting full-chassis I/O configurations.

2. Technical Specifications

• Input Voltage: Supports dual DC input redundancy, with a range of 24–72 VDC (wide adaptability for industrial DC power grids, common in offshore or remote sites).
• Output Voltage: Delivers two regulated output rails:
  • Main rail: 5 VDC (powers system backplane and I/O modules), with ±2% regulation accuracy.
  • Auxiliary rail: 24 VDC (powers external sensors, relays, or accessories), with ±5% regulation accuracy.
• Output Current:
  • 5 VDC rail: Maximum 30 A (capable of powering fully populated Tricon chassis with 16+ I/O modules).
  • 24 VDC rail: Maximum 3 A (supports low-to-medium current auxiliary devices).
• Efficiency: Up to 90% at full load (higher efficiency than previous models, reducing energy consumption and heat buildup).
• Isolation: Input-to-output isolation of 3 kV DC (1 minute), and output-to-chassis isolation of 2 kV DC, preventing cross-interference between power circuits and the safety system.
• Protection Mechanisms:
  • Over-voltage protection (OVP): Triggers at 5.8 VDC (5V rail) and 29 VDC (24V rail) to protect connected modules.
  • Over-current protection (OCP): Current limiting at 35 A (5V rail) and 3.6 A (24V rail) to avoid short-circuit damage.
  • Reverse polarity protection: Prevents module failure if input power is connected incorrectly.
  • Over-temperature protection (OTP): Shuts down at 90°C internal temperature, with automatic recovery when cooled.

3. Core Product Features

• Dual Redundant Architecture: Designed for 1+1 or 2+2 redundancy. If one power supply unit fails, the redundant unit takes over in < 5 ms (zero power interruption), meeting SIL 3 fault-tolerance requirements.
• Hot-Swappable Design: Enables online replacement without shutting down the safety system, minimizing maintenance downtime and avoiding production disruptions.
• Advanced Diagnostics:
  • LED status indicators (Power OK, Fault, Redundancy Active) for at-a-glance monitoring.
  • Real-time data (output voltage, current, internal temperature) transmitted to the Triconex controller, accessible via TriStation 1131 software for remote troubleshooting.
  • Built-in self-test (BIST) function that runs automatically on startup to verify module health.
• Safety & Industry Certifications:
  • Complies with IEC 61508 (SIL 3) for safety integrity, ensuring suitability for ESD and FGS applications.
  • Hazardous area certifications: ATEX (II 2G Ex d IIC T4 Ga) and IECEx (Ex d IIC T4 Ga).
  • Global compliance: UL 508, CSA C22.2 No. 14, CE (EMC/EMI), and RoHS.

4. Operating Environment

• Operating Temperature: -40°C to +75°C (wider range than legacy models, suitable for extreme environments like desert refineries or arctic pipelines).
• Storage Temperature: -40°C to +85°C (supports long-term warehouse storage without performance degradation).
• Humidity: 5%–95% (non-condensing), resistant to moisture in coastal or high-humidity industrial sites.
• Vibration/Shock Resistance:
  • Vibration: IEC 60068-2-6 (10–500 Hz, 0.75 g rms) for continuous operation.
  • Shock: IEC 60068-2-27 (50 g, 11 ms half-sine pulse) for mechanical impact tolerance.

5. Typical Applications

• Oil & Gas: Powers ESD systems on offshore platforms, pipeline monitoring stations, and LNG terminals.
• Petrochemicals: Supplies power to process safety controllers in ethylene plants and chemical reactors.
• Mining: Supports safety systems for underground mining equipment (e.g., conveyor emergency stops) with unstable DC power grids.
• Power Generation: Feeds power to turbine protection systems and nuclear auxiliary safety controllers.
