Siemens Sitop BAT1600 Battery module, lead acid, 24VDC, 12Ah Part number 6EP4135-0GE00-0AY0

Product Overview

The Siemens 6EP4135-0GE00-0AY0 is the Siemens SITOP BAT1600 24 V DC 12 Ah lead-acid battery module — a maintenance-free sealed battery unit designed to provide backup power for SITOP UPS1600 DC-UPS systems. It is used to ensure continuous 24 V DC supply for control systems, automation, and critical loads during mains voltage interruptions or disturbances.

Key Features

• 24 V DC, 12 Ah sealed lead-acid battery module for UPS backup
• Output current up to 40 A continuous in buffering mode
• Short-term peak current up to 120 A (e.g. for transient loads)
• Screw-terminal connections for battery and control wiring
• Includes 50 A/32 V maxi-fuse for safety and overload protection
• Three-colour status indicator (buffer ready / buffer endangered / no buffering possible)
• Wall-mountable housing — suitable for control cabinets and power panels
• Designed for industrial automation and control-system environments
