Technical Specifications AC input, redundant DC output channel. Operating temperature 0 ℃ to +60 ℃, storage temperature ‑40 ℃ to +85 ℃, non‑condensing relative humidity 5%‑95%. Integrated over‑voltage, over‑current and short‑circuit hardware protection.
Functional Features Completes AC‑DC conversion and filtering processing. Supports dual‑channel redundant power output. Realizes seamless power switching when one power channel is abnormal. Front‑panel indicator lamps display each channel running status and fault alarm. Built‑in hardware self‑diagnosis monitors input and output working condition.
Application Scenarios Spare redundant power supply for high‑reliability ABB DCS control rack. Widely applied in power plant and chemical process control cabinet requiring uninterrupted power supply.
Performance Parameters Low‑ripple stable DC output. Non‑interrupt redundant switching performance. Continuous long‑time load‑bearing operation capability.
Material Composition Metal housing. Multilayer glass‑fiber epoxy printed circuit board. Power conversion rectifier, filter and redundant switching assemblies. Input‑output screw wiring terminals and rack fixing hardware.
Structural Characteristics Standard rack‑mount power unit. Front panel equipped with multi‑channel status indicators. Input and output terminals arranged on lower side of housing. Standard mounting holes for rack installation.
Working Principle AC power inputs to power unit, converted into stable DC voltage through rectifier and conversion circuit. Redundant switching circuit monitors two internal power channels in real‑time. When one channel breaks down, system automatically switches to another normal channel without interrupting load power supply.
Installation Requirements Cut off AC input power before replacement. Fasten PHARPS03000000 onto designated rack mounting position. Connect AC input wiring and DC output wiring strictly according to terminal definition. Restore input power, measure DC output voltage and verify rack modules normal power‑on condition.
Usage Notes Reserve sufficient ventilation space for heat dissipation. Hot‑plug under powered state is prohibited. Check redundant switching function simulation after installation.
