Functional Features

1. Universal AC Input: Supports 85–264 VAC (47–63 Hz) for global deployment, eliminating regional power supply constraints.
2. High‑Power Output: 750 W continuous 24 VDC delivery with ±0.5% regulation, powering T8100 chassis and all connected safety I/O modules.
3. 1+1 Redundancy: Enables redundant power pairing with automatic load sharing and failover, eliminating single points of failure in SIS.
4. Hot‑Swap Capability: Allows module replacement without system shutdown, supporting zero‑downtime maintenance and upgrades.
5. Comprehensive Protection: Overvoltage, overcurrent, overtemperature, and short‑circuit protection prevent damage to safety controllers and I/O.
6. SIL 3 Alignment: 1500 VDC input‑output isolation and compliance with IEC 61508 SIL 3 preserve safety integrity for TMR systems.
7. Front‑Panel Diagnostics: LED indicators for input power, output voltage, module fault, and redundancy status enable quick visual troubleshooting.
8. Active PFC: Power factor correction (PF ≥ 0.95) reduces harmonic distortion and improves energy efficiency.
9. Rack‑Mount Design: 1U 19‑inch form factor fits standard industrial enclosures, simplifying system integration.
10. Optional Conformal Coating: Protects internal components from moisture, dust, and chemical contaminants in harsh environments.

Application Scenarios

1. Safety Instrumented Systems (SIS): Deployed in oil & gas and chemical plants to power T8100 SIS controllers, supporting ESD, F&G, and BMS with redundant 24 VDC power and SIL 3 compliance.
2. Refineries & Petrochemical Facilities: Supplies stable power to T8100 expander chassis in DCS‑integrated SIS, ensuring continuous operation of emergency shutdown systems during AC power fluctuations.
3. Nuclear Power Auxiliary Systems: Used in nuclear plant safety systems, delivering isolated 24 VDC to T8100 controllers with redundancy to meet regulatory requirements for fault tolerance.
4. Marine & Offshore Platforms: Powers T8100 SIS on offshore rigs, withstanding extreme temperatures and vibration while providing redundant power for vessel control and safety systems.
5. Pharmaceutical Manufacturing: Supports T8100 batch control SIS, maintaining precise 24 VDC regulation for critical process monitoring and compliance logging.
6. Mining & Heavy Industry: Supplies power to remote T8100 systems in underground mines, with hot‑swap capability enabling maintenance without disrupting ventilation or conveyor safety controls.

Additional Information
