DURAmax DC Uninterruptible Power Supplies

Introduction

Weidmuller’s DURAmax DC Uninterruptible Power Supplies are compact control units designed to maintain 24 V DC backup power for industrial automation systems. The DURAmax line automatically changes to battery operation when a mains interruption occurs, helping support continuity for equipment installed in control cabinets.

What it does

DURAmax DC UPS units provide a backup-power layer for 24 V industrial control systems, including PLCs, sensors, and related automation equipment. They are intended to operate alongside compatible Weidmuller power and battery products: 24 V DC PRO ECO II, PRO MAX, and PRO TOP power supplies, plus DURA ECO battery modules.

The units include temperature-compensated battery charging and battery cold-start capability. LED status diagnostics provide local indication of operating status, while USB Type-C supports configuration with DURAmax DC UPS Manager software.

PUSH IN connection technology is used for wiring, supporting straightforward installation in control-cabinet assemblies.

Applications

• Backup power for PLC-based industrial automation systems
• Maintaining 24 V DC supply during mains interruptions
• Control cabinets containing sensors and other control equipment
• Systems built around compatible PRO ECO II, PRO MAX, or PRO TOP power supplies
• Installations using DURA ECO battery modules for stored backup energy

Design considerations

DURAmax DC UPS units are designed around a 24 V backup-power architecture, so the associated DC power supply and battery module should be selected from the stated compatible product ranges. The battery-related functions include temperature-compensated charging and cold-start capability, making the battery module an important part of the overall system design.

For installation and commissioning, the units use PUSH IN connections and provide a USB-C configuration interface. Integrators can use the USB-C interface with DURAmax DC UPS Manager software when configuration access is required, while the onboard LEDs provide local status diagnostics.
