The Phoenix Contact TRIO3‑UPS/1AC/24DC/5 is a compact, all-in-one industrial-grade uninterruptible power supply (UPS) designed to deliver consistent 24 V DC power even during input power failures. With a robust 5A output capacity and integrated charger, it supports high system availability in control cabinets, automation systems, and critical infrastructure.

Unlike traditional UPS setups, the TRIO3 combines an AC/DC power supply and UPS controller in a single DIN-rail mounted unit, saving valuable panel space and simplifying installation. When paired with compatible external batteries, it provides seamless backup power during outages—ensuring your PLCs, sensors, and controllers remain online.

Key Features & Benefits:

• Integrated Power Supply + UPS Controller
  No need for separate devices—one unit handles both power supply and backup switching.

• Automatic Battery Backup Switching
  Ensures uninterrupted operation during AC input failure (buffer time depends on battery size).

• Input Voltage Range:
  100–240 V AC (85–264 V tolerance), suitable for global installations.

• Output:
  24 V DC / 5 A continuous load capacity.

• Battery Compatibility:
  Designed for use with 24V sealed lead-acid (AGM/VRLA) batteries, including:

  • MINI-BAT/24DC/1.3Ah

  • QUINT-BAT/24DC/3.4Ah

  • QUINT-BAT/24DC/7.2Ah

  • QUINT-BAT/24DC/12Ah

• Status Monitoring & Signaling:
  Front-panel LEDs for real-time power and battery status, along with relay outputs for remote alarms.

• Safety & Protections:
  Overvoltage, overload, short circuit, and deep discharge protection for enhanced durability.

• Mounting:
  Tool-free DIN rail installation with push-in connection technology.

• Operating Temp Range:
  -25 °C to +70 °C — ideal for harsh industrial environments.
