- Material Composition: FR‑4 high‑power printed circuit board; industrial‑grade isolated power‑conversion components; over‑current and over‑temperature protection circuit components; gold‑plated backplane edge connector; metal front‑panel with multi‑color LED indicators; metal heat‑dissipation housing structure.
- Structural Features: Full‑height plug‑in rack‑module mechanical structure; front‑panel LED indicators for input power status, output status and fault alarm; rear‑side gold‑plated edge connector delivers multi‑group DC power to rack backplane bus; internal metal heat‑dissipation structure; mechanical locking latch for rack‑slot fixing.
- Working Principle: Module receives external DC input power. Internal isolated switching‑power circuit converts input voltage into multiple groups of stable isolated DC power supplies required by monitor, communication and relay modules inside rack. When dual redundant power‑supply modules are installed inside rack, two modules work in parallel current‑sharing mode. If one power‑supply module fails, another module automatically bears full‑load power supply without system power interruption. Built‑in protection circuit cuts off output under over‑voltage, over‑current or over‑temperature fault condition.
- Application Scenarios: Power source for complete 3500 machinery‑protection rack; redundant power‑supply backup for turbine‑compressor unit TSI system; power‑supply for petrochemical and power‑plant rotating‑machinery protection racks.
- Installation Requirements: Insert power‑supply module into dedicated power‑supply slot at left‑most position of 3500 rack; lock mechanical latch firmly; complete external DC power input wiring on corresponding I/O termination module; verify input voltage value matches module rated input range; confirm front‑panel normal‑power‑on LED illuminates. For redundant configuration, install two power‑supply modules and connect two independent external DC power sources.
- Usage Notes: Do not exceed rated input‑voltage range; observe heat‑dissipation ventilation requirement for rack cabinet; hot‑swap operation is allowed only under normal redundant power‑supply running condition; inspect LED status in daily inspection work; avoid conductive dust accumulation on power‑supply module surface during long‑term operation.
