Working Principle Input AC voltage goes through EMI filter, rectification and switching conversion circuit, outputs stable 5VDC power. Power supplies each module via rack backplane bus. Protection circuit monitors output status; triggers protection when over‑current or short‑circuit occurs. LED shows normal power‑supply state.
Installation Requirements Install into dedicated power‑supply slot of Series 90‑30 main rack. Strictly implement protective ground for cabinet. Confirm input AC voltage matches nominal range. AC input wiring uses appropriate wire gauge. Cut off AC input power before module replacement, hot‑swap is forbidden. Keep ambient temperature and humidity within specification.
Usage Notes Do not overload total backplane power consumption. Avoid unstable AC input with heavy surge. Keep cabinet ventilation unobstructed. Check POWER‑OK LED regularly. Forbid on‑site disassembly of power supply unit. Stay away from dust accumulation, corrosive gas and liquid splash.
