Weidmuller has introduced the DURAmax DC UPS, a compact 24 V uninterruptible power supply designed to keep PLCs, sensors and other industrial automation devices running during mains power interruptions. The unit automatically switches loads to battery power when the DC input voltage drops, helping prevent unexpected shutdowns and production downtime.

Key Characteristics

• Output voltage: 24 V DC
• Current ratings: 5 A, 10 A, 20 A and 40 A variants
• Order numbers: 2934940000 (5A), 2934950000 (10A), 2934960000 (20A), 2934970000 (40A)
• Automatic switchover to battery when DC input voltage drops
• Configuration: USB-C interface + Windows-based DURAmax DC UPS Manager software
• Front-panel LED indicators for operating status, battery condition and faults
• Remote control: 3 relay outputs + 3 transistor outputs
• Cyclic battery availability check by the UPS controller
• Battery operating temperature (charge/discharge): −15 °C to +50 °C
• Separate control input to lock battery operation
• Temperature-compensated battery charging
• Integrated deep-discharge protection
• Battery cold-start function
• PUSH-IN connections with clearly labelled terminals
• Compatible with Weidmuller PRO ECO II, PRO MAX and PRO TOP 24 V DC power supplies + DURA ECO battery modules
• Designed with cybersecurity readiness (including EU Cyber Resilience Act)

The compact form factor makes the DURAmax DC UPS suitable for space-constrained industrial control cabinets while providing comprehensive battery management, diagnostics and remote signalling.

Target Applications

• Machine building
• Process automation
• Plant control systems
• Industrial control cabinets requiring uninterrupted 24 V DC supply
