ABB 48980001AP

The ABB 48980001AP (48980001-AP) is an industrial DC/DC converter identified as the DSSB-146. It is designed to convert an incoming DC voltage into a regulated low-voltage DC output for compatible industrial electronic equipment.

This converter is used in industrial control and electronic power supply applications where stable DC power is required. It is particularly relevant to maintenance and replacement of compatible legacy ABB equipment.

2. Technical Parameters

The listed output voltage and current correspond to a nominal output capacity of 10 W. The 13 W figure is the rated power stated in the product listing; confirm the applicable rating and operating conditions against the original unit before installation.

3. Product Features

• DC/DC power conversion: Converts an 18–32 V DC input into a 5 V DC output for compatible electronic loads.

• Stable low-voltage supply: Supports electronic circuits that require a regulated 5 V power source.

• Industrial application: Intended for use in industrial control equipment and electronic assemblies.

• Compact converter design: Integrates power conversion circuitry into an equipment-specific module.

• Legacy spare-parts support: The part number helps identify replacement units for older installations.

4. Structural Composition

The converter typically incorporates the following functional sections:

1. Input power interface: Receives the incoming DC supply.

2. DC/DC conversion circuit: Converts the input voltage to the required lower DC voltage.

3. Voltage regulation circuitry: Maintains the output within its specified operating range.

4. Output interface: Delivers the converted DC power to the connected equipment.

5. Protection circuitry: May incorporate protection against electrical faults, depending on the specific hardware revision.

6. Enclosure and mounting structure: Supports installation within the designated industrial equipment.

5. Application Fields

The ABB DSSB-146 converter may be used in compatible applications such as:

• Industrial automation control cabinets.

• Electronic control and interface assemblies.

• Legacy ABB automation equipment maintenance.

• Low-voltage electronic power supply systems.

• Industrial equipment repair and restoration.

• Replacement of existing DC/DC converter modules.

Actual suitability depends on the host equipment's electrical requirements and connector configuration.

6. Conclusion

The ABB 48980001AP, also designated 48980001-AP / DSSB-146, is an industrial DC/DC converter with a listed input range of 18–32 V DC and a 5 V DC output rated at 2 A.
