Honeywell CC-PWRR01 Redundant Power Supply Module

The Honeywell CC-PWRR01, also cataloged as the CC-PWRR01 Redundant Power Supply Module, operates as a dedicated hardware component for regulated 24 VDC bus power generation and load-sharing delivery within Honeywell Experion PKS platforms.

Hardware Specifications

Channel-to-Channel Isolation & Regulated Loop Power Infrastructure

The CC-PWRR01 converts incoming wide-range AC utility power into a stabilized 24 VDC output rail designed to energize controller backplanes, IOTA carriers, and field instrument loops. Integrated decoupling diodes enable parallel connection across dual-supply configurations without risk of back-feeding during a primary source failure. The internal power conversion stages incorporate galvanically isolated transformer barriers to isolate central system logic from mains voltage spikes, common-mode noise, and ground loops across distributed process I/O channels.

Frequently Asked Questions

Q: Can a failed CC-PWRR01 module be replaced while the system backplane is fully energized?

A: Yes, the CC-PWRR01 features hot-swappable architecture, allowing online removal and replacement under active power without interrupting the 24 VDC rail to connected I/O modules.

Q: How is thermal dissipation managed within the CC-PWRR01 enclosure during high-load conditions?

A: Thermal management relies entirely on natural convection cooling across internal heat sinks, eliminating mechanical fan failure points within sealed control cabinets.

Q: What input AC line variations can the CC-PWRR01 power supply tolerate without output voltage degradation?

A: The module accepts input voltages ranging from 85 to 264 VAC across line frequencies of 47 to 63 Hz while maintaining tight output regulation at 24 VDC up to a 5 A load.

Field Installation Guidelines

1. Mount the CC-PWRR01 module vertically onto the DIN rail or backplane carrier to optimize vertical airflow across the convection cooling vents.
2. Connect primary AC line power using recommended conductor gauges, verifying tight terminal screw engagement to prevent localized thermal hot spots.
3. Establish a low-impedance earth ground conductor to the cabinet ground stud to enable proper surge suppression and filter noise dissipation.
4. Verify parallel load distribution across both units in a dual-redundant configuration prior to fully loading downstream field channels.
