Siemens Sitop UPS1600 UPS with Ethernet/ Profinet, 24VDC, 20A Part number 6EP4136-3AB00-2AY0

Product Overview

The Siemens 6EP4136-3AB00-2AY0 is the Siemens SITOP UPS1600 24 V DC / 20 A uninterruptible power supply (DC-UPS) with Ethernet/PROFINET interface. It is designed to provide buffered 24 V DC power to automation systems — maintaining stable supply during voltage drops or mains failure — and offers enhanced integration and monitoring capabilities through its network interface.

Key Features

• DC-UPS module delivering 24 V DC output at up to 20 A continuous current
• Input voltage range: 21 … 29 V DC — suitable for standard 24 V DC industrial power systems
• Supports battery-backed buffering when paired with compatible battery modules — protecting against power interruptions
• Built-in short-circuit and overload protection; output is short-circuit proof under specified conditions
• Output remains 24 V DC in buffering mode; maintains reliable supply for connected loads
• Compact, DIN-rail mountable housing — suitable for control cabinets and automation panels
• Integrated Ethernet/PROFINET interface — allows remote monitoring, diagnostics and system integration (e.g. via OPC UA or network management) when configured accordingly
• Automatic battery charge management and status indication (mains OK, battery, alarm) when battery module is connected
• High efficiency design — minimal power loss when operating near rated current

Technical Specifications

• Article Number: 6EP4136-3AB00-2AY0
• Product Type: SITOP UPS1600 DC-UPS, 24 V DC / 20 A
• Input Supply (DC): 24 V DC nominal
• Input Voltage Range: 21 … 29 V DC
• Rated Output Voltage: 24 V DC (in normal and buffering modes)
• Rated Output Current: 20 A continuous
• Peak / Overload Capacity: Temporary overloads supported (as per module design limits)
• Buffered Output Behaviour: Output remains 24 V DC when input fails and a battery module is connected
• Short-Circuit / Overload Protection: Output is short-circuit proof under defined conditions; electronic current limiting applies
• Mounting: DIN-rail (standard 35 mm) — for easy integration in control cabinets
• Interface: Ethernet / PROFINET (for remote monitoring and integration)
• Battery Support: Compatible with SITOP battery modules (e.g. UPS1100 / BAT1600 series) for buffering supply during outages
• Power Capacity: 480 W (24 V × 20 A)
• Operating Conditions: Industrial-grade — designed for typical control-cabinet environments

Compliance & Certifications

• Built as part of the SITOP UPS1600 series — meeting Siemens industrial power-supply standards
• Designed for use in DIN-rail mounted control panels, switchgear and automation enclosures
• Suitable for global industrial installations requiring DC power buffering and reliability under supply faults
• Supports integration via Ethernet/PROFINET for monitoring, diagnostics and networked automation control

Applications

The 6EP4136-3AB00-2AY0 UPS module is ideal for industrial automation systems, control cabinets, PLC setups, remote I/O racks, and any 24 V DC equipment that requires continuous, reliable power despite mains instability. When paired with a compatible battery module, it ensures continuous operation during power interruptions — suitable for critical control systems, process automation, safety circuits, data logging, communication devices and remote equipment in factories, infrastructure or process plants.
