Front‑panel LED indicator shows power‑good and fault status. Delivers stable high‑current power output for chassis backplane.
Application Scenarios RX7i main rack power supply Industrial automation control cabinet Medium‑load RX7i control rack Legacy equipment spare‑part replacement
Performance Parameters High‑efficiency AC‑DC power conversion performance. Rapid trigger response for all fault protection actions. Shock and Vibration: Complies with IEC 60068 industrial environmental standard
Material Composition Module housing: Flame‑retardant metal‑reinforced industrial housing PCB substrate: High‑temperature resistant power‑supply printed‑circuit board Bus contact fingers: Gold‑plated copper alloy Internal components: Switching power conversion circuit and protection component group
Structural Characteristics Standard RX7i plug‑in power supply module form‑factor. Front‑panel LED indicators for power‑good and fault status. AC input screw terminal block. Gold‑plated backplane bus contact fingers. Internal switching AC‑DC conversion circuit assembly. Spring‑loaded mechanical locking latch.
Working Principle External AC power connects to module input terminal block. Internal switching power circuit completes AC‑DC conversion and voltage stabilization processing. Regulated 5VDC high‑current power transmits to RX7i chassis backplane for all plug‑in modules. Multi‑protection circuit cuts output automatically when overload, short‑circuit or over‑temperature conditions appear.
Installation Requirements Insert module into dedicated power supply slot of RX7i chassis. Complete reliable cabinet protective earthing connection. Confirm input AC voltage matches on‑site power grid specification. Calculate total power consumption of all rack modules.
Usage Notes Do not exceed maximum rated output power capacity. Inspect AC input power stability in regular maintenance work.
