Overview Manuals Applications Efficiency Safety & Compliance Installation

Features:

  • Accepts the documented 400–500 V AC three-phase supply range.
  • Provides a regulated 24 V DC output rated at 10 A and 240 W.
  • Mounts on a standard DIN rail within an industrial control enclosure.
This order code identifies the 10 A PSU300S configuration rather than another current class in the SITOP family. The input, output and mechanical details must therefore be checked against the complete article number.

Its role is to establish a stable control-voltage bus for automation equipment that cannot be supplied directly from the three-phase feeder. The unit is suitable for machines and process panels with a centralized 24 V distribution scheme.

Before installation, calculate continuous demand and simultaneous inrush, then coordinate upstream protection with the conductor rating. Leave the prescribed cooling space so heat from drives or contactors does not reduce the available power margin.

  • Create a regulated DC bus for controller racks and remote interface stations.
  • Power cabinet relays, sensors and signaling circuits from a three-phase plant feed.
  • Standardize 24 V auxiliary distribution in machinery with a documented 240 W demand.
  • The 240 W rating corresponds to the full 24 V DC output at the specified 10 A load.
  • A centralized supply avoids multiple small AC/DC converters scattered through the enclosure.
  • Load planning should preserve reserve capacity for simultaneous switching events.
  • Coordinate the three-phase branch device with the supply input and local electrical code.
  • Protect downstream distribution branches according to their conductor and connected-load limits.
  • A bonded protective-earth path must be present before the mains terminals are made live.
  • Use the specified rail orientation so natural convection passes through the housing correctly.
  • Keep ventilation openings clear of wire duct, covers and adjacent heat-producing equipment.
  • Terminate the 24 V distribution only after polarity and cable sizing have been checked.
Description
6EP1434-2BA20 is built around a three-phase input stage for industrial mains systems between 400 and 500 V AC. The regulated 24 V DC output delivers 10 A continuously, giving machine builders a clearly defined 240 W source for control electronics, interface devices and auxiliary circuits.

Within a cabinet, this SITOP PSU300S can consolidate the DC demand of PLC hardware, signaling equipment and field interfaces while keeping the control rail independent from line-side fluctuations. DIN-rail construction and a compact enclosure allow the supply to sit close to the loads it serves without requiring a separate mounting plate.

Engineering the installation calls for more than matching the nominal wattage. The designer must account for start-up peaks, feeder protection, conductor cross-section, protective-earth continuity, heat from neighboring devices and the airflow available at full load, because those factors determine whether the 24 V rail remains dependable in service.

Technical notes
6EP1434-2BA20 must not be energized until all three input phases, the protective-earth conductor and the upstream isolating device have been verified; loss of PE or obstructed convection creates a serious cabinet hazard.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why does Siemens 6EP1434-2BA20 require a three-phase cabinet feeder?
Its input stage is specified for 400–500 V AC across a three-phase system, so it is not a single-phase substitute.
How is the 240 W figure for Siemens 6EP1434-2BA20 obtained?
The rating follows from the regulated 24 V output operating at the stated 10 A continuous current.
What cabinet role is best suited to Siemens 6EP1434-2BA20?
It is intended to establish a shared 24 V DC control rail for automation electronics and auxiliary loads.
Which transient loads should be included when sizing Siemens 6EP1434-2BA20?
Include PLC start-up, relay and solenoid pickup, interface inrush and any loads that can switch on at the same time.
Can Siemens 6EP1434-2BA20 be mounted directly beside a drive?
Only when the documented spacing and cabinet temperature remain acceptable; drive heat must not obstruct PSU convection.
What information allows an accurate Siemens 6EP1434-2BA20 supply review?
State the three-phase line voltage, calculated 24 V demand, peak-load profile, enclosure conditions, quantity and destination.
