Description

The Honeywell CC-PWR401 is a 40 Ampere power system module engineered to supply 24 Vdc power within Honeywell control system enclosures. Constructed as a 40 Amp power rack populated with three 24 Vdc (20 A) output power supplies, the assembly delivers up to 40 Amperes of redundant system power.

Operating from standard 120/240 VAC line power across a 47 to 63 Hz frequency range, each individual 24 Vdc power supply unit can be powered by an independent AC source, such as separate mains feeds or an Uninterruptible Power Supply (UPS). The system maintains a regulated 25 to 26 Vdc output under normal AC input conditions, capped at a maximum of 20 Amperes from any single DC output connector.

The CC-PWR401 is designed specifically for direct AC-to-DC conversion and does not support battery backup integration. Its multi-supply modular structure provides continuous operation and power distribution for industrial process automation racks and cabinet control equipment.

Features

• 40 A Power Capacity: Houses three 20 A output power supply units inside a dedicated 40 A power rack chassis.
• Redundant Power Configuration: Delivers 40 Amperes total output with failure-tolerant multi-supply architecture.
• Independent Input Feeds: Allows each individual 24 Vdc power supply to connect to separate AC line or UPS power sources.
• Regulated DC Output: Provides steady 25 to 26 Vdc output voltage under normal operating conditions.
• Connector Current Limiting: Built-in output rating limits maximum current to 20 Amperes per individual DC output connector.
• Extended Temperature Rating: Built to operate across industrial ambient temperatures ranging from -40 degC to +70 degC.
• Wide Frequency Acceptance: Accommodates AC line input frequencies from 47 to 63 Hz.

Applications

• Process Control Cabinets: Delivers primary 24 Vdc power to Honeywell DCS control racks and field I/O systems.
• Redundant Power Infrastructure: Provides dual-feed power distribution for critical control loops requiring isolated AC power inputs.
• Control Panel Power Distribution: Functions as the central 24 Vdc system supply within industrial automation control panels.

Installation Guidelines

1. Pre-Installation Inspection: Unpack the CC-PWR401 power rack and verify that all three 24 Vdc supply units are properly seated in the chassis prior to mounting.
2. AC Source Allocation: To achieve true power redundancy, connect each internal power supply to an independent AC power circuit or UPS line feed.
3. DC Output Wiring: Route 24 Vdc distribution cables ensuring total current draw on any individual DC output connector does not exceed the 20 Ampere limit.
4. Thermal Clearance: Mount the module within the enclosure allowing adequate vertical airflow to maintain operating temperatures within the -40 degC to +70 degC envelope.
5. Grounding: Verify proper protective conductor grounding to the chassis frame before energizing AC input power.

Replacement Recommendations

• Load Verification: Prior to replacing an existing power rack unit, verify that the connected 24 Vdc field load does not exceed the 40 A total system rating.
• AC Feed Isolation: Disconnect incoming AC line power feeds before handling main power wiring during complete system replacement.
• Post-Replacement Checks: Measure output terminals post-installation to confirm DC voltage remains within the nominal 25 to 26 Vdc specification.
