Phoenix UNO Series: Industrial Power Supplies, UPS & Redundancy Modules - Selection Guide 

Product Overview

The Phoenix UNO Series comprises high-reliability industrial power supplies, UPS uninterruptible power modules, and diode redundancy modules, designed for stable power delivery in automation systems. Covering AC-DC (1AC/2AC input) and DC-DC (350-900DC input) power conversion, UPS backup, and dual-input redundancy functions, these modules offer output voltages of 24V DC/48V DC and power ratings from 60W to 960W. With industrial-grade durability, wide input voltage ranges, and built-in protection features, they’re ideal for distributed automation, control systems, and critical equipment—ensuring uninterrupted power against outages, voltage fluctuations, and transient interruptions.

Application Scenarios & Recommended Models

1. High-Power 24V DC Load Supply

• Requirement: 24V DC 40A heavy-load power (large motors, dense I/O)

• Recommended Model: 1110043 (UNO2-PS/1AC/24DC/960W)

• Key Reason: Ultra-high 960W power output; single AC input simplifies wiring

• Requirement: 24V DC 20A mid-range load (automation control systems)

• Recommended Model: 2910105 (UNO2-PS/1AC/24DC/480W)

• Key Reason: Balanced power and size; reliable for 24/7 industrial operation

2. DC-DC High-Voltage Conversion

• Requirement: 350~900V DC high-voltage to 24V DC power
• Recommended Model: 2906300 (UNO-PS/350-900DC/24DC/60W)
• Key Reason: Wide high-voltage input range; 60W stable output for sensitive devices

3. Uninterrupted Power Supply (UPS)

• Requirement: 24V DC critical equipment (PLCs) backup power
• Recommended Model: 2905907 (UNO-UPS/24DC/24DC/60W)
• Key Reason: UPS function ensures no power interruption during outages

4. Low-Voltage DC Redundancy

• Requirement: 5~24V DC dual-input redundancy (prevent single power failure)
• Recommended Model: 2905489 (UNO-DIODE/5-24DC/2X10/1X20)
• Key Reason: Diode-based redundancy; 2×10A input → 20A output for load protection

5. 48V DC Equipment Power

• Requirement: 48V DC communication modules/drives power supply
• Recommended Model: 1110155 (UNO2-PS/1AC/48DC/240W)
• Key Reason: 48V DC fixed output; 240W power fits mid-range 48V devices

Core Advantages

• Wide Power Range: 60W~960W covers light to heavy industrial loads
• Dual Input Types: Supports AC (100~240V) and DC (5~900V) input for diverse systems
• Reliability Functions: UPS backup and diode redundancy eliminate single points of failure
• High Efficiency: Up to 90% efficiency reduces energy consumption and heat generation
• Industrial-Grade Durability: -25℃~70℃ operating temperature, IP20 protection, and robust components
• Compact Design: DIN rail mounting saves cabinet space, even for high-power (960W) models
• Global Compliance: CE/UL/CSA certifications enable international deployment

Installation & Usage Notes

• Voltage Matching: Ensure input voltage aligns with module ratings (e.g., AC models avoid DC input; high-voltage DC models match 350~900V range)
• Load Limitation: Do not exceed maximum output current (e.g., 40A for 960W model); use parallel modules for higher current needs
• Heat Dissipation: Reserve ≥10mm space between modules, especially for high-power (480W~960W) variants
• Wiring Specifications: Use 1.5~6mm² conductors based on current (larger gauge for high-power models); tighten terminals to prevent voltage drop
• Redundancy Setup: For UNO-DIODE, use identical power supplies for dual inputs to ensure compatibility
• UPS Maintenance: For UNO-UPS, connect to backup battery (if required) and test backup function regularly
• Polarity Attention: DC input/output models require correct polarity; reverse polarity protection is built-in but avoid forced miswiring
