The Meanwell DUPS40 is a DC-UPS DIN rail controller that manages transfer between a primary 24VDC power supply and a backup battery, maintaining uninterruptible 24V supply at up to 40A. It automatically switches to battery when mains power fails, and returns to mains supply when power is restored.

Technical specifications:

• Part number: DUPS40
• Manufacturer: Meanwell
• Series: DUPS
• Output voltage: 24V DC (adjustable)
• Output current: 40A (maximum)
• Output power: 960W
• Input voltage: 24V DC
• Efficiency: N/A
• Input source: 24VDC from external DIN rail PSU
• Battery type compatible: sealed lead-acid (SLA) or lithium 24V
• Transfer time to battery: less than 20ms
• Cooling: Fanless, free air convection
• Operating temperature: -20C to +70C (with derating above 50C)
• DIN rail: TS-35 (35mm standard)
• Dimensions: 100x85x90mm (L x W x H)
• Case material: Metal
• Certifications: CB, CE, cURus, TUV

Features and benefits:

• Universal 24V DC input accepts any mains voltage worldwide without input switching
• Fanless convection cooling – no moving parts, suitable for dusty or sealed enclosures
• N/A efficiency reduces heat dissipation in sealed enclosures
• Wide operating temperature range suitable for outdoor cabinets and harsh industrial environments
• TS-35 DIN rail mounting compatible with any standard industrial panel

Applications:

• Control panels requiring uninterruptible 24V at up to 40A
• Industrial automation panels with safe-shutdown battery backup
• Building management and SCADA systems requiring 24V supply continuity

Compliant with CB, CE, cURus, and TUV safety standards.
