Technical Specifications Input voltage 100‑240 V AC, wide range automatic adaptation. Output 24 V DC, rated output power 48 W. Operating temperature 0 ℃ to +60 ℃, storage temperature ‑40 ℃ to +85 ℃, non‑condensing relative humidity 5%‑95%. Protection grade IP20 for module surface. Complies with CE, IEC 61010 industrial control standards.
Functional Features Provides stable 24 V DC power for DCS rack internal units. Supports hot‑swap replacement without system power shutdown. Built‑in over‑voltage, over‑current and short‑circuit protection. Front‑panel LED indicators display power status and fault alarm. Supports redundant parallel operation mode.
Application Scenarios Deployed in Freelance DCS control cabinet. Applied for chemical, power, metallurgy industrial process control system. Used for new project construction and spare‑part replacement.
Performance Parameters Output voltage fluctuation keeps within ±1%. Protection circuit responds rapidly under abnormal condition. Hot‑swap function maintains uninterrupted power supply for rack. Fault signal can be uploaded to system diagnosis platform.
Material Composition Multilayer glass‑fiber epoxy printed circuit board. Switch power semiconductor components, filter and isolation components. Metal alloy module housing. Screw‑type power terminals. Copper alloy contact pieces for back‑plane connector.
Installation Requirements Insert module into designated rack slot and tighten locking screw. Connect AC input power according to rated specification. Ensure cabinet protective grounding is reliable. Verify LED normal indication after power‑on. Configure redundant parameter if parallel operation is required.
Usage Notes Anti‑static protection shall be adopted during handling. Disconnect input power when conducting complete disassembly. Periodically check terminal tightening torque. Prevent conductive dust and corrosive gas accumulation. Execute module replacement in accordance with DCS maintenance workflow.
