Description
Product Overview
The Honeywell CC-PWRB01 is a redundant power system designed for compatible Experion Series C process-control installations. Its configuration combines two 24 VDC power supplies with a rechargeable battery-backup assembly, supporting continued DC power delivery during a qualifying AC input failure. The assembly is identified by part number 51199940-100 and is intended for applications where power continuity is important to controller operation and process monitoring. Its battery-backed configuration distinguishes it from the CC-PWRR01, which provides redundant supplies without the integrated 24 V battery backup.
The Honeywell CC-PWRB01 supplies 24 VDC nominal power, with published specifications reporting approximately 25–26 VDC while AC input is available and 24–25 VDC during battery operation. The documented system supports output current up to 20 A and battery backup for up to 30 minutes at the specified load. The assembly includes six DC distribution connections, an interface for C300 controller memory-backup assemblies, and a connector for power-system alarm contacts. Each supply may be fed from a separate AC source when the installation is designed for that arrangement. Actual backup duration depends on battery age, charge state, environmental conditions, and connected load.
When sourcing the Honeywell CC-PWRB01, verify the complete assembly number, installed revision, and battery configuration. The power supplies and rechargeable batteries have different service-life expectations, so a unit that passes a basic power-on check may still require battery replacement or a load test. Honeywell maintenance guidance identifies an approximate service life of 3–5 years for the 24 V battery backup, with actual life affected by operating conditions. Before commissioning a replacement, confirm the AC input arrangement, DC load, redundancy status, alarm contacts, and battery-backup response against the applicable Series C documentation.
Product Introduction
A loss of AC power can interrupt control-system operation if the cabinet power arrangement lacks sufficient redundancy and backup capacity. The Honeywell CC-PWRB01 combines two 20 A power supplies with a 24 V battery-backup assembly for compatible Series C installations.
Its documented backup target is up to 30 minutes at the specified load. Verify battery health, output voltage, alarm operation, and cabinet loading before returning the system to service.

Frequently Asked Questions
What is the Honeywell CC- used for?
It provides redundant 24 VDC power and battery backup for compatible Experion Series C control hardware. Its configuration is intended to help maintain DC power during a qualifying AC input failure.
Can I hot-swap a power supply in the CC-?
The Series C design documentation describes removable power-supply components, but maintenance must follow the applicable Honeywell procedure. Confirm the redundancy state, supply condition, and required electrical precautions before removing any component. Do not assume that the entire assembly or battery pack can be replaced live.
Does the CC- support firmware v3.1?
The CC- is a power-system assembly rather than a conventional programmable controller. Check the hardware revision, compatible power-supply components, battery assembly, and any related monitoring or controller software requirements in the applicable system documentation.
Is CC- interchangeable with CC-PWRR01?
Not as a complete like-for-like replacement when battery backup is required. CC- includes the 24 V battery-backup assembly, while CC-PWRR01 provides redundant supplies without that integrated backup. Replacing CC- with CC-PWRR01 changes the system’s response to AC input failure.
How long does the battery backup last?
The documented target is up to 30 minutes at 20 A under specified conditions. Actual duration depends on battery condition, charge state, temperature, and connected load. Test the battery-backed output under the approved procedure rather than relying on the nominal duration alone.
How can I verify that a replacement is in good condition?
Check the model and assembly number, inspect the power supplies and battery assembly, and request condition details and test records. Testing should cover DC output under load, redundancy behavior, battery charging and backup operation, and alarm contacts. A basic power-on test alone does not establish battery health.
What should be checked before commissioning?
Confirm the AC input, DC load, supply redundancy, battery condition, distribution connections, and alarm wiring. Verify the output voltage and backup response in accordance with the applicable Series C maintenance procedure before relying on the assembly for process control.
Procurement recommendation: Specify Honeywell CC-, part number 51199940-100. Confirm that the offered unit includes the required battery-backup assembly and that its batteries have been inspected and tested. A matching model number alone does not establish the remaining battery capacity or the condition of the power supplies.
