- Front‑panel LED indicators show input‑power status, output‑voltage status and module fault‑alarm
- Fault‑relay dry‑contact output for external remote power‑fault alarm linkage
- Low output‑ripple performance, suppress power‑supply noise interference to safety‑system I/O signals
- Automatic recovery mechanism after short‑circuit‑fault removal
- Wide universal AC‑input range, adapt to global industrial‑site power‑grid conditions
Working Principle: AC input power goes through EMI filter, rectifier‑circuit and power‑factor correction unit. High‑frequency switching conversion circuit generates stable regulated 24 V DC output. Multiple T3500 modules connected in parallel implement active current sharing to distribute total load evenly. Internal monitoring circuit continuously samples input voltage, output voltage, output current and internal component temperature. When over‑voltage, over‑current, over‑temperature or short‑circuit fault occurs, module activates protection action, triggers fault‑indicator and remote‑alarm relay output. After fault condition disappears, module can restore normal operation automatically. Single power‑supply‑module failure under N+1 configuration will not cause rack power‑supply interruption.
Material Composition & Structural Characteristics:
- Housing: Heavy‑duty die‑cast aluminum alloy shell, act as heat‑dissipation and electromagnetic‑shielding carrier
- Internal circuit board: Multi‑layer FR‑4 power‑grade printed circuit board, adopt industrial‑grade switching‑power semiconductor components
- Connectors: Gold‑plated backplane power‑transmission connector, AC‑input screw terminal block
- Front panel: Flame‑retardant engineering plastic with LED indicator window and fault‑relay terminal interface, IP20 protection grade
- Plug‑in card‑type structure for Regent‑Plus dedicated power‑supply‑rack slot installation
Installation Requirements:
- Insert T3500 into dedicated power‑supply slot of Regent‑Plus power rack, tighten front‑panel locking screws
- For redundant N+1 configuration, install quantity of modules according to total rack load calculation result
- AC input power wiring must use flame‑retardant power cables, match local power‑grid specification
- Cabinet protective ground connection must be reliable, ground resistance ≤4 Ω
- Maintain sufficient air‑flow clearance around power‑supply modules for heat dissipation
- Do not install in location with poor ventilation, high‑temperature ambient or direct‑heat‑radiation exposure
- AC‑input side configure external fuse protection complying with module rated‑input‑current
Application Scenarios:
- Regent‑Plus safety‑system main rack and expander‑rack power‑supply source
- Petrochemical ESD safety‑instrumented‑system redundant power‑supply configuration
- Off‑shore platform fire‑gas safety‑system fault‑tolerant power‑supply
- Chemical‑plant safety‑interlock control cabinet power‑supply unit
- Power‑plant safety‑instrumented‑system redundant power‑supply infrastructure
Usage Notes:
- Hot‑swap operation only permitted under remaining redundant power‑modules maintain full‑load‑capacity condition
- Module shell disassembly is forbidden; internal high‑voltage circuit exists, no user‑serviceable parts
- Strictly calculate total system load before redundant‑module quantity configuration
- Do not exceed maximum rated output‑current of single module
- After module replacement, verify output‑voltage accuracy and parallel current‑sharing performance
- Operate strictly within rated operating temperature range
- Periodically inspect AC‑input wiring‑terminal fastening torque and cabinet ventilation condition
