ABB Bailey 7760690157 SPS02-48V2VAA System Power Supply

ABB SPS02-48V2VAA 008279R001 Power Supply Module

Product Overview

The SPS02-48V2VAA (008279R001/7760690157) is a high-performance system power supply module within the ABB Symphony Plus / Harmony (Bailey INFI 90) control architecture. This module is specifically designed to convert a 48 VDC input source into the regulated DC voltages required by the system backplane to power processing units, communication modules, and I/O interfaces.

As a core power component, the SPS02-48V2VAA (008279R001) is engineered for high-availability industrial environments. It features advanced voltage regulation, filtering, and protection circuitry to ensure that mission-critical control logic remains unaffected by input power fluctuations. Its integration into the Symphony Plus system allows for comprehensive diagnostic monitoring, reporting health status directly to the control network.
