Phoenix QUINT Series: Power Redundancy, UPS & Buffer Modules - Selection Guide 

Product Overview

The Phoenix QUINT Series includes high-reliability power redundancy modules, UPS systems, buffer modules, and diode rectifiers, designed to ensure uninterrupted power supply for industrial automation systems. Covering AC/DC UPS (120/230V AC input), DC redundancy (ORING/DIODE modules), DC-UPS (24/48V DC), and buffer modules, these products support high current ratings (up to 80A), redundant power configuration, and seamless switchover. With industrial-grade durability, wide temperature adaptation, and DIN rail mounting, they’re ideal for critical applications like PLCs, sensors, and control systems in manufacturing, process control, and power distribution—protecting against power outages, voltage fluctuations, and transient interruptions.

Application Scenarios & Recommended Models

1. Industrial Power Redundancy Systems

• Requirement: 24V DC high-current (≥40A) redundant power supply

• Recommended Model: 2902879 (QUINT-ORING/24DC/2X40/1X80)

• Key Reason: Dual 40A input → 80A output, ORING redundancy ensures continuous power if one input fails

• Requirement: 48V DC redundant power for medium loads

• Recommended Model: 2320160 (QUINT-DIODE/48DC/2X20/1X40)

• Key Reason: Diode-based redundancy, prevents reverse current, fits 48V DC systems

2. Critical AC Equipment Uninterrupted Power

• Requirement: 230V AC high-power (2.5KVA) UPS for servers/controllers

• Recommended Model: 1136815 (QUINT-HP-UPS/230AC/2.5KVA/PT)

• Key Reason: PT-compatible, online UPS design, stable output for sensitive AC equipment

• Requirement: 120V AC standard-load (1.5KVA) backup

• Recommended Model: 1136804 (QUINT-HP-UPS/120AC/1.5KVA/PT)

• Key Reason: 适配 North American 120V grid, reliable backup for office/industrial AC devices

3. DC Device Long-Term Backup

• Requirement: 24V DC heavy-load (40A) backup for motors/valves

• Recommended Model: 2866242 (QUINT-DC-UPS/24DC/40)

• Key Reason: 40A high output, supports long-term backup for power-hungry DC devices

• Requirement: 48V DC UPS battery backup

• Recommended Model: 1133819 (QUINT-HP-BAT/48DC/7.0AH/PT)

• Key Reason: 7.0AH capacity, lead-acid AGM technology, matches QUINT-HP-UPS 48V systems

4. Transient Power Interruption Protection

• Requirement: 24V DC buffer for short-term power cuts (e.g., PLCs)
• Recommended Models: 2320393 (40A), 2866213 (20A)
• Key Reason: ≤1ms response, buffers voltage dips/short outages to protect sensitive electronics

Core Advantages

• Redundancy & Backup: ORING/diode redundancy and UPS systems eliminate single points of failure
• High Current Capacity: Up to 80A output supports heavy industrial loads
• Seamless Switchover: ≤1ms switchover time ensures no power interruption for critical devices
• Wide Voltage Adaptation: Covers 12-48V DC and 120/230V AC, matching global power grids
• Industrial-Grade Durability: -25℃~70℃ operating temperature, robust protection against harsh conditions
• Easy Integration: DIN rail mounting and standard terminals simplify cabinet installation
• Battery Compatibility: Supports maintenance-free lead-acid batteries for long backup durations

Installation & Usage Notes

• Voltage Matching: Ensure input/output voltage matches the module’s rating (e.g., 24V DC modules for 24V systems)
• Redundancy Configuration: For ORING/diode modules, use identical power supplies for dual inputs to ensure compatibility
• Battery Maintenance: Charge UPS batteries every 3-6 months; store at 0-40℃ to extend lifespan
• Heat Dissipation: Reserve ≥10mm space between modules, especially for high-current (40A+) models
• Wiring Specifications: Use 0.5~4mm² conductors based on current; tighten terminals to prevent voltage drop
• UPS Setup: For AC UPS models, connect PT signals (if needed) for enhanced monitoring and control
• Buffer Module Placement: Install buffer modules close to sensitive devices (e.g., PLCs) to minimize wire length and voltage loss
