Product Overview

6EP1337-3BA00 is a Siemens SITOP PSU100M stabilized power supply for converting a selectable 120 V or 230 V AC input into an isolated industrial DC control supply.

The output can be adjusted from 24 to 28.8 V DC and supplies 40 A continuously, with short-term power boost and selectable short-circuit behavior for demanding startup and fault conditions.

Natural-convection cooling, DIN-rail mounting, visual status indication and compatibility with SITOP buffer and signaling modules support integration into control cabinets.

Ordering focus: confirm the complete article number, line-voltage jumper setting, load current, protective device, rail size and required cabinet clearances.

Key Functions

High-Current Stabilized Output

The supply delivers a regulated 40 A output with an adjustable voltage range from 24 to 28.8 V DC.

Power Boost and Fault Response

A 120 A boost is available for 25 ms, and the short-circuit response can use an approximately 46 A constant-current characteristic or latching shutdown.

Control-Cabinet Integration

The 240 mm-wide enclosure snaps onto an EN 60715 rail and provides LED indication for normal output, overload and latching shutdown.

Frequently Asked Questions

How do I select the input range on 6EP1337-3BA00?

Set the device wire jumper for the available 120 V or 230 V AC supply before energizing the unit.

Can 6EP1337-3BA00 ride through a brief mains interruption?

The power supply provides at least 20 ms of buffering at a 230 V AC input while delivering the rated output current.

What overload capability is available from 6EP1337-3BA00?

The unit can deliver 120 A for 25 ms and can sustain an approximately 46 A short-circuit current under its selectable protection characteristic.

Can I connect two 6EP1337-3BA00 units in parallel?

Up to two power supplies may be connected in parallel when additional output power is required and the installation follows the documented parallel-operation arrangement.

Which mounting space should I reserve for 6EP1337-3BA00?

Install the unit on a 35 × 15 mm DIN rail and keep 50 mm of free space above and below for natural convection.

How can I read the operating state of 6EP1337-3BA00?

A green LED indicates the 24 V output is present, while yellow and red indications identify overload and latching shutdown conditions.

When does temperature derating begin for 6EP1337-3BA00?

Full rated output is available up to 60 °C, after which the current is reduced by 2.5% per kelvin through 70 °C.

Compatibility & Ordering Notes

Before ordering 6EP1337-3BA00: verify the 120/230 V AC network, required 40 A load capacity, branch protection, DIN-rail dimensions and cabinet ventilation.

Input and Protection Coordination

• Set the line-voltage jumper for the installed network before energizing the supply.
• Coordinate the upstream protective device with the documented input current and inrush-energy values.

Mounting and Cooling

• Use an EN 60715 35 × 15 mm DIN rail and maintain 50 mm clear space above and below the enclosure.
• Apply the specified output derating when the ambient temperature exceeds 60 °C.

System Expansion

• Select SITOP buffer or signaling accessories only when their electrical function matches the required control-power architecture.
• Use matched wiring and protection when operating up to two supplies in parallel for increased output power.
