Battery Maintenance
Features:
- Combines redundant 20 A DC supplies with a 24 V backup assembly.
- Specified battery support is up to 30 minutes at 20 A under the documented conditions.
- Battery condition and power-system alarms are part of the maintenance plan.
The Honeywell CC-PWRB01 addresses two different loss-of-power conditions in a Series C cabinet. Its two AC supplies provide redundancy during normal powered operation, while the separate 24 V backup subsystem supports the DC load for a limited period after mains power is unavailable. Honeywell identifies the complete configuration as assembly 51199940-100. The backup rating is conditional on load and battery condition, and must not be treated as unlimited operation or a substitute for the plant power-continuity design.
For a replacement order, distinguish the complete system from a supply module, battery rack or battery kit. Inspect the existing charging and alarm arrangements, record battery age and capacity-test results, and identify all components included in the shipment. Honeywell gives different maintenance intervals for supplies, main backup batteries and memory batteries. Qualified personnel should follow the approved service procedure and verify the DC output, supply alarms and battery alarm response after maintenance, with process effects assessed in advance.
The CC-PWRB01 Honeywell Battery-Backed Power System may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
Honeywell CC-PWRB01 documentation and reference links.
Important Notice: These selected original Honeywell pages retain both document covers. Electrical ratings, component scope and service-life advice must be read with their stated conditions; the service note is not an EOL announcement.
The backup assembly is specified for up to 30 minutes at a 20 A load under the manufacturer conditions. That is a design rating, not a guaranteed duration for an aged battery. Establish usable capacity by the approved test and account for actual cabinet load, temperature and battery history.
The battery subsystem includes charging and monitoring functions in addition to the two normal AC supply paths. Review the applicable wiring and alarm diagrams for the installed revision. Confirm that battery and supply faults reach the intended control-system alarms; a normal supply output does not prove battery readiness.
Honeywell lists a typical three-to-five-year interval for main 24 V backup batteries, affected by temperature, charging and discharge history. Its service guidance calls for capacity checks and replacement when performance is inadequate. This battery interval must not be confused with the separate power-supply service-life guidance or a product EOL date.
