Phoenix QUINT-DC-UPS/24DC/40 Uninterruptible power supply

The Phoenix QUINT-DC-UPS/24DC/40 is a high-performance uninterruptible power supply (UPS) designed for universal use, specifically engineered to buffer long-term power interruptions. Equipped with long-life lead-acid batteries, it delivers extended buffer times even at high currents, ensuring connected devices operate without interruption—even during prolonged supply voltage failures.
Ideal for space-constrained environments like DIN rail installations in control cabinets, its narrow and uniform design optimizes space usage. Short wiring paths further enhance order and clarity within control cabinets, simplifying maintenance and reducing the risk of wiring errors.

2. Key Features

2.1 Space-Saving & Cost-Effective Design

• Compact Form Factor: Fits seamlessly on 35mm horizontal DIN rails (per EN 60715) with dimensions of 66 x 130 x 125mm (2.598 x 5.118 x 4.921 in.) in default position, and 122 x 130 x 69mm (4.803 x 5.118 x 2.717 in.) when rotated 90°, saving valuable cabinet space.
• Integrated Diode: Isolates buffered and unbuffered loads, eliminating the need for additional isolation components and reducing costs. It also protects connected devices from internal network errors.
• Plug-and-Play Convenience: Ready-to-use plug-in bridges minimize installation time, while no extra hardware is required for system shutdown (configurable via device settings or external signals).

2.2 Maximum System Availability

• Professional Battery Management: Ensures long battery life and reliable performance through:
• Automatic presence check (every 60 seconds) to confirm battery connectivity.
• Weekly automatic quality tests to detect battery degradation early.
• Temperature-compensated charging to optimize charge cycles based on ambient conditions.
• Electronic overcurrent protection to prevent battery damage from excessive current.
• Reliable Signaling: 3 floating PDT contacts (30V AC/DC, max 1A) and 3 LEDs (green, yellow, red) provide clear real-time status updates, enabling quick decision-making in emergencies.
• Short-Circuit Resistant Signaling: A current-limited, short-circuit-resistant positive supply output protects relay contacts from welding due to wiring errors, ensuring trustworthy "OK" signals.

2.3 Flexible Load Management

• Isolated Input: Enables separation of buffered (critical) and unbuffered (non-critical) loads. This extends buffer time (dependent on output current) and allows use of smaller battery modules for cost and space savings.

• Parallel Battery Support: Battery modules can be connected in parallel to increase buffer time, adapting to varying power backup needs.
