Functional Features:

  • Dual independent AC input channels, seamless switch‑over upon one mains source failure
  • Support N+1 parallel redundant operation, realize active current sharing among multiple T8223 modules
  • Hot‑swap support for online module replacement without interrupting rack power output
  • Full‑range internal hardware diagnostics, monitor input status, output load level and thermal condition
  • Front‑panel LED array indicates AC input health, DC output status and fault alarm events
  • Timestamped fault‑message upload to system fault historian
  • Built‑in inrush‑current suppression circuit, reduce impact to upstream power distribution equipment
  • Thermal derating mechanism activates automatically under high‑ambient‑temperature condition

Working Principle: Two independent AC input loops receive mains power supply. Each AC path flows through EMI filtering, rectification and power‑factor correction circuit. High‑frequency switching power conversion circuits generate stable 24 VDC output. Multiple parallel T8223 modules distribute total load current evenly via active current‑sharing control logic. Internal monitoring circuit continuously captures electrical and thermal operating parameters. Fault condition triggers hardware protection and fault flag output. Single AC input branch or single power‑module failure under N+1 configuration will not cut off rack power‑supply output.

Material Composition & Structural Characteristics:

  • Housing: Reinforced die‑cast aluminum alloy shell, enhance heat‑dissipation and electromagnetic‑shielding performance
  • Circuit substrate: Multi‑layer FR‑4 power‑grade printed circuit board, adopt high‑power industrial switching components
  • Backplane connector: Gold‑plated high‑density vibration‑resistant industrial connector
  • Front panel: Flame‑retardant PC engineering plastic with LED indicator window, IP20 protection grade
  • Plug‑in card‑type structure for Trusted chassis dedicated power‑supply‑slot installation

Installation Requirements:

  • Insert T8223 into dedicated power‑supply slot of Trusted main or expander rack, tighten front‑panel locking screws
  • Dual‑AC input connect to two physically separated upstream power distribution circuits
  • For N+1 redundant setup, calculate total rack load accurately to confirm required module quantity
  • AC power wiring follow local industrial electrical specification, install external upstream fuse protection
  • Cabinet protective ground resistance ≤4 Ω
  • Maintain sufficient air‑flow clearance around modules for heat dissipation
  • Keep installation location away from corrosive gas and continuous mechanical shock environment

Application Scenarios:

  • Large‑scale high‑density Trusted I/O expander rack power supply
  • Petrochemical large‑scale ESD safety‑instrumented‑system redundant power infrastructure
  • Chemical complex multi‑loop safety‑interlock cabinet power conversion unit
  • Power‑plant safety‑critical control system heavy‑load power supply
  • Off‑shore oil‑gas platform large‑capacity safety‑system rack power source

Usage Notes:

  • Hot‑swap operation only allowed when remaining redundant modules can bear full rack load
  • Module shell disassembly is forbidden, internal high‑voltage circuits exist
  • Strictly implement load calculation before deploying N+1 parallel configuration
  • After module replacement, verify dual‑input switching, current‑sharing performance and all diagnostic functions
  • Operate strictly within rated operating temperature range
  • Periodically inspect AC wiring terminals and cabinet internal ventilation condition
