[ PRODUCT ]

The ABB DSSR170 48990001-PC is a high-reliability DC-to-DC voltage regulator module serving as a crucial power management component within the ABB MasterPiece 200 Series. The unit is engineered to accept a standard industrial 24V DC input and down-step it into a tightly regulated, stable 5V DC output supplying up to 10A of continuous load current. It incorporates plug-and-play hotline swapping capabilities, built-in diagnostic safety loops, and distinct green/red LED diagnostic lights to immediately alert technicians of undervoltage states or operational circuit faults.

[ Application ]

(1) MasterPiece 200 I/O Subracks: Plugs directly into specialized power bus backplanes to distribute a steady logic voltage layer to adjacent processing modules.

(2) Redundant Power Converter Topologies: Configured within localized power architectures alongside multiple DSSR 170 units and a DSSS 171 module to achieve an high-availability system redundancy.

(3) Live-System Hot Swapping: Deployed in critical manufacturing environments where faulty voltage units must be swapped mid-operation without cutting main cabinet line power or interrupting system operations.

(4) Low-Voltage Industrial Logic Infrastructure: Acts as a central 5V DC step-down regulator across machine control grids, building automation lines, and legacy chemical process control units requiring filtered, low-ripple logic rails.

What Happens After You Order?

Step 1 Email confirmation

After checking out or requesting a quote, you will receive an email confirming that we have received your order. Your quote will be accepted or your web order will be placed.

Step 2 Dedicated customer service rep

One of our customer service reps will be in touch to verify your part(s) and confirm your shipping details.

There's also a principle running through everything amikon does that doesn't show up on a spec sheet: if a customer can't find their part anywhere else, the team will track it down. No dead ends. That's a promise, not a marketing line.

If your line is down or you're trying to source a part that everyone else has given up on, the story continues. So does the search.
