- Material Composition: FR‑4 multilayer power‑supply printed‑circuit board; high‑efficiency switch‑mode power‑supply transformer; EMI line‑filter components; over‑voltage, short‑circuit protection circuit components; gold‑plated back‑plane edge connector; metal front‑panel with OK status LED; reinforced plastic mechanical locking latch.
- Structural Features: Half‑height plug‑in rack‑module mechanical structure; front‑panel green OK LED indicator for power‑supply health status; rear‑side gold‑plated edge connector mates with rack back‑plane bus; power‑input wiring connects to rear‑side dedicated power‑input termination assembly; mechanical locking latch secures module inside far‑left rack power‑supply slot.
- Working Principle: Alternating‑current mains input passes through built‑in EMI noise‑filter circuit, enters high‑efficiency switch‑mode power‑supply circuit. Power‑supply converts variable‑range AC input into multiple stable regulated DC voltage rails required by all 3500 functional modules. Output power distributes to every rack slot via rack internal back‑plane bus. Two power‑supply units run in parallel redundant mode; if primary unit fails, backup unit instantly takes over full rack‑load power‑supply without system power‑interruption. Internal self‑diagnosis circuit continuously monitors each DC output voltage level, triggers fault indication when output exceeds tolerance range.
- Application Scenarios: Redundant power‑supply for critical steam‑turbine and centrifugal‑compressor 3500 TSI racks; industrial sites with unstable AC mains voltage fluctuation; petrochemical and thermal‑power‑plant machinery‑protection system requiring zero power‑interruption redundancy; new‑project and retrofit spare‑part application for universal‑AC‑input 3500 racks.
- Installation Requirements: Insert half‑height power‑supply modules into the two dedicated far‑left power‑supply slots of rack; lower‑slot unit serves as primary power‑supply, upper‑slot unit serves as backup power‑supply; fully engage mechanical locking latch for each power‑supply module; complete AC mains input wiring to matched power‑input termination assembly; verify front‑panel OK LED illuminates steadily after power‑on; perform redundant‑switch‑over test to confirm backup‑power function validity.
- Usage Notes: Execute ESD static‑protection measures during module handling and replacement; hot‑swap operation is permitted only when redundant partner power‑supply module keeps normal working status; strictly comply with input‑voltage range specification, do not apply over‑voltage input; inspect front‑panel OK LED status during daily equipment‑inspection rounds; avoid exposing power‑supply module to oil‑mist and corrosive‑gas environment.
