Description
Bently 3500/15‑01‑01‑00 (127610‑01)
- Key Features: Half‑height plug‑in rack‑module form factor; low‑voltage AC input range 85‑132 Vac rms; integrated EMI line‑noise filter; dual‑unit redundant parallel‑operation architecture; each single power‑supply unit can support full‑rack load independently; hot‑swap maintainable under redundant‑operation condition; front‑panel OK LED health‑status indicator; internal multi‑rail output‑voltage self‑diagnosis; built‑in over‑voltage and short‑circuit protection functions.
- Technical Specifications & Performance Parameters
- Input voltage range: 85 Vac ~ 132 Vac rms low‑voltage AC
- Form factor: Half‑height rack‑module
- Operating temperature: 0 ℃ ~ +60 ℃
- Storage temperature: ‑40 ℃ ~ +85 ℃
- Weight: 0.80 kg
- Material Composition: FR‑4 multilayer power‑supply printed‑circuit board; switch‑mode power‑supply transformer; EMI filter components; over‑current and over‑voltage protection circuit devices; gold‑plated back‑plane edge connector; metal front‑panel with OK status LED indicator; reinforced plastic mechanical locking latch assembly.
- Structural Features: Half‑height plug‑in rack‑module mechanical construction; front‑panel green OK LED indicates normal power‑supply working status; rear‑side gold‑plated edge connector mates with rack back‑plane bus; field AC‑mains wiring connects to rear‑side dedicated power‑input termination hardware; mechanical locking latch fastens module inside rack far‑left power‑supply slot.
- Working Principle: Low‑voltage AC mains input passes through EMI noise‑filter circuit and enters switch‑mode power‑supply conversion circuit. Module converts AC input to multiple stable DC output voltage rails required by every 3500 monitor, communication and relay module. Two power‑supply modules installed in two left‑side slots work in parallel redundant mode. Lower‑slot unit acts as primary power‑supply, upper‑slot unit serves as automatic backup. When primary unit fails, backup unit instantly bears full rack‑load without power‑supply interruption for whole rack system. Internal self‑diagnosis circuit continuously monitors every DC output voltage level and triggers fault indication when output deviates from allowable tolerance range.
- Application Scenarios: Redundant power‑supply for 3500 TSI racks powered by 110 Vac industrial mains power supply; overseas industrial project sites adopting low‑voltage AC power grid; petrochemical and power‑plant rotating‑machinery‑protection systems requiring power‑supply redundancy; spare‑part replacement for existing low‑voltage‑AC 3500 rack installations.
- Installation Requirements: Insert two half‑height power‑supply modules into dedicated far‑left two power‑supply slots of rack; lower‑slot unit works as primary power‑supply, upper‑slot unit works as backup power‑supply; fully lock mechanical latch for each power‑supply module; complete low‑voltage AC mains wiring to matched power‑input termination assembly; confirm front‑panel OK LED keeps steady illumination after power‑on; execute manual power‑supply switch‑over test to verify redundant backup‑function performance.
- Usage Notes: Adopt ESD anti‑static protection during module handling and replacement; hot‑swap operation can only be performed when redundant partner power‑supply remains normal working; strictly follow rated input‑voltage range, prohibit high‑voltage AC input beyond specification; observe front‑panel OK LED status during daily inspection rounds; prevent oil‑mist and corrosive‑substance contamination to power‑supply module circuit components.
