ABB article 3BSE088189R1 identifies SD854, a G3-compliant 20 A power supply with 100–240 V AC or 110–150 V DC input and adjustable 24–28 V DC output. Use it for the documented 24 V DC control load where the required current and redundancy arrangement fit SD854. Confirm the exact article, 20 A load requirement, input source, output setting, DIN-rail orientation, upstream protection, wiring and cabinet thermal design.
SD854 3BSE088189R1 is selected from the complete manufacturer identity and receiving-system evidence. Isolate the source, set the output as required, preserve polarity/earth and maintain horizontal DIN-rail mounting and ventilation clearances. Measure output voltage and load current, confirm regulation and alarms, then test the intended redundancy or supply-failure response.
Verify the AC or DC source, upstream fuse and earthing before wiring SD854.
Calculate continuous load, inrush and redundancy sharing before setting the output voltage.
Measure voltage, current, regulation and alarm behavior under the intended cabinet load.
SD854 is the 20 A member of the documented supply family. Its adjustable 24–28 V DC output must be set for the actual control system, while conductor size, protection and total steady/inrush load remain part of the cabinet design.
ABB specifies horizontal DIN-rail mounting and G3 compliance. Maintain airflow and spacing, verify any redundancy/decoupling arrangement, and test load sharing or transfer behavior without exceeding either supply path.
Availability and lifecycle status are confirmed for the exact SD854 3BSE088189R1 article at quotation.
Moore Automated verifies the supplied condition, included items and installed-system match against the complete manufacturer identity.
The replacement must be commissioned with the checks listed in the technical sections.
