Features:
- The documented type designation is CPS01, and this value must match the supplied unit.
- The documented product type is Control power-supply unit, and this value must match the supplied unit.
- The documented control system is Bailey INFI 90 / Symphony, and this value must match the supplied unit.
ABB CPS01 is a Control power-supply unit documented for the applicable Bailey Infi 90 system configuration. Its recorded specification includes type designation CPS01, product type Control power-supply unit, control system Bailey INFI 90 / Symphony. Correct selection depends on the complete article identity, installed equipment, mechanical or electrical interfaces and the documented configuration rather than appearance alone. Using the exact model helps maintenance teams avoid incompatible revisions, connector arrangements and application variants.
Before installing CPS01, record the original nameplate, installed position, connected assemblies and every relevant configuration detail. Compare the supplied unit with the existing hardware and applicable ABB service documentation, isolate all affected energy sources and preserve required settings or calibration data. After installation, inspect each affected interface and complete controlled functional checks before returning the equipment to service.
The CPS01 ABB Control power-supply unit is listed as Active / Available from OEM. Current revision, availability and supplied scope are confirmed in the written quotation.

Important Notice: Every linked document must identify the listed model or its documented family. Confirm the complete order code, hardware revision and installed-system requirements before replacement.
Hardware Definition: Control rack power module/single-phase switching power supply.
Main Task: Primarily installed in a standard modular unit (MMU), responsible for converting externally input single-phase AC power into the high-precision, high-stability 24V DC power required by internal system components (e.g., main controller, security/general-purpose I/O modules, communication modules, and display terminals).
High Reliability Design: Features excellent electromagnetic interference (EMI) immunity, outstanding thermal stability, overload protection, and voltage fluctuation protection circuitry, effectively reducing control system crashes or shutdowns caused by power instability.
On the field spare parts warehouse or equipment nameplate, you will typically see the following two specific model numbers:
1.CPS01-A: Primarily used in the control layer within control cabinets, providing a clean system-level power input for the underlying control cards and communication buses.
2.CPS01-B: Typically used as a rack-mount switching power supply, designed to provide independent power support for process control cabinets and human-machine interface terminals (such as operator workstations, display units, panels, etc.).
CPS01 is selected as part of the Bailey modular control-power arrangement rather than as a generic supply. Verify the MPS chassis location, connector keying and the installed INFI 90 or Symphony hardware record.
