Technical Specifications Input 100‑240 V AC wide range. Rated output 24 V DC, output power 120 W. Operating temperature 0 ℃ to +60 ℃, storage temperature ‑40 ℃ to +85 ℃, non‑condensing relative humidity 5%‑95%. Module surface IP20. Meets CE and IEC industrial power supply requirements.
Functional Features Provides high‑power stable DC power for DCS rack. Built‑in over‑voltage, over‑current, short‑circuit and over‑temperature protection. Front‑panel LED indicates power‑on and fault information. Supports hot‑swap and redundant parallel operation.
Application Scenarios Equipped in high‑load ABB DCS control cabinet. Suitable for chemical, petrochemical and power industry process control. Used for new project construction and spare‑part replacement.
Performance Parameters Output voltage fluctuation remains within allowable range. Multiple protection mechanisms respond rapidly. Hot‑swap replacement will not affect running system. Fault status can be uploaded to system diagnosis unit.
Material Composition Multi‑layer glass‑fiber epoxy printed circuit board. High‑power switch‑mode power components, filter and isolation components. Metal reinforced housing. Screw‑type power terminals. Copper‑alloy back‑plane contact pieces.
Structural Characteristics Rack‑mount plug‑in module structure. Front panel is equipped with multi‑group LED indicators. Rear side connects rack back‑plane bus. Module width 25 mm, height 130 mm, depth 130 mm.
Working Principle AC input passes EMI filter and rectifier circuit. High‑frequency switching circuit completes voltage conversion and stabilization. High‑power 24 V DC power is output to rack back‑plane bus. Internal monitoring circuit detects working status in real‑time and triggers protection and alarm when abnormality appears.
Installation Requirements Insert module into specified rack slot and tighten locking screw. Complete AC input wiring according to rated power parameter. Ensure cabinet protective grounding is reliable. Check LED indication after power‑on.
Usage Notes Anti‑static protection shall be adopted during handling. Disconnect input power before complete disassembly. Never exceed rated output power. Periodically check terminal tightening torque. Prevent dust accumulation inside module.
