ABB 086388-001
Product Name: ABB 086388-001 rack-mount power supply.
Product Introduction: Converts wide-range AC mains into stabilized 24 V DC for PLC/DCS I/O, sensors and communication hardware inside control cabinets.
Technical Specifications: Input 85–264 V AC; output 24 V DC; rated output 5 A; operating temperature -20°C to +60°C; storage -40°C to +85°C; transient response less than 20 ms; IP20 rack unit; natural convection cooling; weight about 0.82 kg.
Detailed content
Functional Features: Regulated 24 V output; overvoltage, overcurrent, short-circuit and overtemperature protection; DC-OK LED; DCS/PLC rack auxiliary power compatibility.
Application Scenarios: Power plants, petrochemical control cabinets, manufacturing automation racks, spare-power stocking for ABB control systems.
Performance Parameters: 120 W output class at 24 V/5 A; wide AC input for global supply systems; industrial regulation grade.
Material And Structure: Euro-card/rack-mount industrial enclosure; PCB with switched-mode power section; status indicator and terminal block.
Working Principle: Rectifies and filters AC input, switches/regulates to 24 V DC, monitors load and temperature, and disconnects or limits output under fault conditions while indicating DC-OK.
Installation Requirements: Mount in the designated rack/cabinet position with ventilation clearance; connect AC input through protective isolation; verify output before connecting field loads.
Usage Notes: Do not exceed 5 A continuous. Maintain convection space, check DC-OK status regularly and replace if protection trips repeatedly.
