- Converts a 24 VDC input to a regulated 5 VDC output rated at 10 A
- Uses ABB spare-fuse reference 56722011-21 with a documented 5 A rating
- Documented for ABB controller and S100 I/O power-supply installations
DSSR 170 48990001-PC is an ABB DC input and output power-supply unit that converts a 24 VDC input into a regulated 5 VDC output for supported control-system loads.
ABB specifies a regulated output capacity of 10 A and identifies 56722011-21 as the associated 5 A spare fuse. The input, output, fuse arrangement and connected load must all be confirmed before a replacement is selected.
ABB product data places the supply in documented Advant Controller, MasterPiece and S100 I/O environments, including AC410, AC450 and AC460-related configurations. Before replacement, verify the complete 48990001-PC identity and preserve the existing input, output and fuse wiring records.
