Features

Three-phase wide-range input

The 340 to 550 V AC range supports industrial 400 to 500 V three-phase systems.

Adjustable DC output

The regulated output can be set from 24 to 28 V DC for control-system requirements.

Dynamic overload capacity

Extra Power provides 150 percent rated current for five seconds per minute.

Compact rail mounting

The 50 mm wide housing mounts on standard 35 mm DIN rail with natural convection cooling.

Interfaces

AC input	Screw terminals L1, L2, L3 and PE accept 0.05 to 2.5 square mm conductors.
DC output	Two positive and two negative screw terminals accept 0.2 to 2.5 square mm conductors.
Signaling	Terminals 13 and 14 provide the published signaling contact.
Protective earth	Protection class I requires the specified PE connection.
Mounting rail	Install on a 35 mm DIN rail according to EN 60715.

Installation

01 - Verify the complete article number

Match 6EP1433-2BA20 on the Siemens label, quotation and packaging.

02 - Check the input system

Confirm a three-phase source within 340 to 550 V AC and 47 to 63 Hz, with correct upstream protection and PE.

03 - Mount with clearance

Install on 35 mm DIN rail and maintain at least 40 mm clearance above and below for natural convection.

04 - Wire input and output

Use conductor sizes within the published terminal ranges and observe polarity on the 24 V DC output.

05 - Set and test the output

Adjust only within 24 to 28 V DC and verify load, signaling and overload behavior before connecting the control system.

FAQ

Q1. How can the exact quoted 6EP1433-2BA20 be verified?

Match the full Siemens order number on the nameplate, quotation and packaging. Confirm SITOP PSU300S, three-phase 400 to 500 V AC input and 24 V DC 5 A output.

Q2. How can New, Used or Refurbished condition be distinguished?

Request current photos of the label, L1/L2/L3/PE terminals, DC output terminals, signaling contact, adjustment control, DIN-rail latch and packaging. Check screw marks, heat discoloration and changed labels.

Q3. How should supplier legality and reliability be checked?

Verify the legal entity, registered address, payment beneficiary and traceable contact. The offer should state Siemens, SITOP PSU300S, 6EP1433-2BA20, condition and quantity.

Q4. Which specifications must engineering confirm before purchase?

Confirm 340 to 550 V AC three-phase input, 24 to 28 V DC adjustment, 5 A rated output, 150 percent Extra Power, 50 x 125 x 120 mm dimensions, 0.5 kg weight, terminal sizes and -25 to +70 degrees C operation.

Q5. What physical evidence should be requested before payment?

Ask for date-marked photos showing the complete nameplate, article number, all input and output terminals, signaling contact, adjustment control, housing and sealed packaging.

Q6. Can another 6EP1433 suffix replace 6EP1433-2BA20?

Not automatically. Similar SITOP units can differ in input phases, voltage range, output current, signaling, approvals and dimensions. Match the complete suffix and application requirements before substitution.
