Technical Specifications AC input voltage range 100‑240 V AC. Output rated 24 V DC, maximum output current 8 A. Back‑plane power distribution interface. Operating temperature 0 ℃ to +60 ℃, storage temperature ‑40 ℃ to +85 ℃, non‑condensing relative humidity 5%‑95%. Built‑in over‑voltage, over‑current and over‑temperature protection circuit.
Functional Features Converts alternating‑current input into stable DC output for rack‑based control hardware. Distributes DC power to back‑plane bus for all plug‑in modules. Front‑panel LED indicators display power input status, normal output and fault alarm. Built‑in hardware self‑diagnosis monitors internal circuit and protection trigger status.
Application Scenarios Power supply spare part for ABB legacy industrial control rack. Applied in renovation and maintenance of process‑industry automation control cabinets.
Performance Parameters Stable DC voltage output performance. Complete multi‑layer electrical protection mechanism. Fast fault response upon abnormal operating condition.
Material Composition Flame‑retardant plastic module housing. Multilayer glass‑fiber epoxy printed circuit board. High‑frequency switching conversion, rectifier and protection assemblies. Back‑plane plug‑in power connector and AC input terminals.
Structural Characteristics Standard rack plug‑in power module. Front side fitted with AC input terminals and status LED indicators. Rear side connects to rack back‑plane power bus. Weight approximately 0.52 kg.
Working Principle External AC power enters DPW01 through input terminals. Internal high‑frequency switching circuit completes voltage conversion, rectification and filtering. Regulated DC power is delivered to rack back‑plane to supply all plug‑in modules. Protection circuit activates and cuts off output when over‑voltage, over‑current or over‑temperature occurs.
Installation Requirements Insert DPW01 into target rack slot and lock fixing latch. Connect AC input wiring to front‑end terminals. Confirm back‑plane connector is fully engaged. Restore AC power supply, measure DC output voltage and verify power supply status indication.
Usage Notes Input AC voltage must conform to module rated range. Do not exceed maximum output load capacity.
