Functional Features

  1. 750W High-Density Output: Delivers 24Vdc regulated power for Trusted backplanes and 28Vdc adjustable field power for I/O modules/FTAs.
  2. Universal 110/240Vac Input: Auto-switches between input voltages for global deployment without manual configuration.
  3. N+1 Redundancy Support: Enables redundant power configurations to eliminate single-point power failures.
  4. Hot-Swappable Design: Allows module replacement without system shutdown, minimizing maintenance downtime.
  5. Active Current Sharing: Balances load across redundant modules to ensure even power distribution and extended component life.
  6. Power Factor Correction (PFC): ≥0.95 power factor reduces harmonic distortion and improves energy efficiency.
  7. Multi-Layer Protection: Overvoltage, overcurrent, overtemperature, and short-circuit protection safeguard system components.
  8. Adjustable 28Vdc Field Power: Provides flexible power for field devices requiring higher voltage than standard 24Vdc.
  9. Real-Time Fault Diagnostics: Monitors input/output status, faults, and temperature; reports alerts via power shelf diagnostics bus.
  10. Low Ripple & Noise: ≤50mV peak-to-peak ripple ensures stable power for sensitive safety system electronics.
  11. IEC 61508 SIL 3 Compatibility: Certified for use in safety-critical SIS applications requiring fault-tolerant power.
  12. Plug-and-Play Integration: Seamlessly fits Trusted 19-inch power shelves; auto-detected by system diagnostics for easy setup.

Application Scenarios

  1. Oil & Gas Refinery ESD Systems: Powers Trusted T8100 chassis and T8400 digital output modules for emergency shutdown (ESD) valve control; N+1 redundancy prevents power-related spurious trips in high-risk refinery environments.
  2. Chemical Plant Reactor Safety Loops: Supplies 24Vdc to T8450 analog output modules and 28Vdc to field sensors/actuators; hot-swappable design allows power module maintenance during non-critical batch phases.
  3. Power Generation Turbine Protection: Delivers stable power to Trusted T8442 speed monitor modules and T8850C FTAs; current sharing and PFC ensure reliable operation during grid voltage fluctuations.
  4. Marine Offshore FPSO F&G Systems: Powers Trusted fire & gas (F&G) control systems; overvoltage/overcurrent protection shields electronics from saltwater-induced corrosion and transient voltage spikes.
  5. Mining Hoist Safety Control: Supplies 24Vdc to Trusted I/O modules controlling hoist brake solenoids; real-time diagnostics alert operators to power anomalies before critical failures.
  6. Pharmaceutical Batch Process Control: Provides regulated power to FDA-compliant Trusted systems; low ripple/noise ensures accurate analog signal transmission for validation-ready process data.
