Technical Specifications

Key Features and Benefits

• High Output Capacity for Demanding Loads: The 8U-PWSP01-CN delivers 20 amps continuously, powering multiple controllers and field devices from a single supply. This capacity reduces the need for multiple smaller supplies, simplifying panel layout and reducing installation costs.

• Wide-Range Universal Input: You can connect this module to any standard industrial AC source without manual switching. It automatically accepts 100-240VAC, 50/60Hz, making it suitable for global installations and facilities with mixed power systems.

• Exceptional Energy Efficiency: With >90% efficiency, this power supply generates less heat than conventional designs. Consequently, you can mount it in sealed enclosures without excessive thermal buildup, extending the life of nearby components.

• Comprehensive Protection Features: The module safeguards both itself and connected equipment against common electrical faults. Built-in overload, overvoltage, overtemperature, and short circuit protection ensure reliable operation under adverse conditions.

• Compact Space-Saving Design: Despite its 20A output capacity, the 8U-PWSP01-CN maintains a compact 125mm x 100mm x 75mm footprint. This small size allows dense packing in control cabinets where space comes at a premium.

Detailed Functional Description

The primary function of the Honeywell 8U-PWSP01-CN involves converting incoming AC mains power into stable, regulated 24VDC for industrial control systems. Specifically, it employs switch-mode technology with power factor correction to achieve high efficiency while minimizing harmonic distortion on the AC line. The module maintains output voltage within ±2% across all line and load conditions, ensuring sensitive electronics receive clean, consistent power. Furthermore, the built-in hold-up time provides >20 ms of ride-through capability during brief AC power interruptions, preventing nuisance system resets.

Output Characteristics and Performance

We designed the 8U-PWSP01-CN to deliver clean DC power suitable for all types of industrial loads. The output exhibits less than 100 mVp-p ripple and noise, meeting the requirements of analog circuits and communication interfaces. For motor starting and other high-inrush applications, the module handles momentary overloads up to 150% for several seconds without shutdown. Additionally, the green LED indicator provides immediate visual confirmation of normal operation, while a red LED signals overload conditions for quick troubleshooting.

Protection and Safety Features

The 8U-PWSP01-CN incorporates multiple protection mechanisms to ensure system integrity:

• Overload Protection: Automatic current limiting with hiccup mode recovery protects against excessive loads

• Overvoltage Protection: Crowbar circuit activates at 28-32VDC, requiring a power cycle to reset

• Overtemperature Protection: Thermal shutdown with automatic recovery when temperature normalizes

• Short Circuit Protection: Continuous protection with no damage to the module under any output short condition

• Input Transient Protection: Internal varistors and filters suppress line surges and spikes

Mechanical and Installation Details

The Honeywell 8U-PWSP01-CN features a rugged metal housing designed for industrial environments. Its DIN rail mounting clip allows tool-less installation on standard TS35 rails, significantly reducing mounting time compared to panel-mount supplies. The front-facing terminals accept wires from 12 to 22 AWG, with clear labeling for input, output, and ground connections. A protective cover over the terminals prevents accidental contact with live connections, enhancing safety during maintenance.

Integration with Control Systems

You can integrate the 8U-PWSP01-CN seamlessly into any 24VDC control system architecture. Its regulated output directly powers Honeywell controllers, I/O modules, and field devices without additional conditioning. The module’s DC OK relay contact provides a remote status signal to monitoring systems, enabling automated alerts for power supply faults. For redundant power configurations, you can connect two 8U-PWSP01-CN units in parallel using external decoupling diodes, creating a fault-tolerant power architecture.
