More Information

Overview Manuals Source Changeover Characteristic Switches Status Interpretation Output Coordination

Features:

  • 6EP1333-3BA00 supplies a regulated 24 V DC rail at a 5 A rating.
  • A de-energized selector aligns the converter with the available AC source range.
  • Front switches choose single or parallel behavior and the overload response.
The 6EP1333-3BA00 links a one- or two-phase feeder to an isolated DC load circuit.

Its duplicated positive and negative terminals distribute one regulated output rather than independent channels.

Selector position, characteristic switches and LED state provide three separate checks before load troubleshooting begins.

The Siemens 6EP1333-3BA00 SITOP PSU200M Stabilized Power Supply may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Matching the selector to the incoming AC feed

  • Low range: The first path accepts 85–264 V AC.
  • High range: The second path accepts 176–550 V AC.
  • Switch state: The factory position is 230 V and the selector is moved only while de-energized.
  • Two-phase feed: Line conductors use L1 and N/L2 with the protective conductor on PE.

What switches A and B change

  • Switch A off: The hard characteristic holds voltage independently of output current in single operation.
  • Switch A on: The soft characteristic allows current sharing during parallel operation.
  • Switch B off: Constant-current mode reduces voltage as overload passes the current limit.
  • Switch B on: Latching mode shuts the supply down when overload pulls the output below 20 V.

Separating normal, overload and shutdown states

  • Green indication: Output voltage is above 20 V ±0.5 V in normal operation.
  • Yellow indication: Overload has reduced the output below the 20 V threshold in constant-current mode.
  • Red indication: Latching shutdown or remote switch-off is present with the signaling module.
  • No green LED: The unit has no supply voltage at its input.

Relating voltage adjustment to current and cooling

  • Factory setting: The output is supplied at 24 V DC.
  • Adjustment span: The potentiometer raises the setting as far as 28.8 V.
  • Current derating: Above 24 V, permitted output current falls by 4% for each additional volt.
  • Thermal alternative: The allowable ambient temperature may instead be reduced by 3 °C for each additional volt.
Description
Siemens 6EP1333-3BA00 is the 5 A member of the SITOP PSU200M modular power-supply family. It converts a one- or two-phase AC feed into a regulated, isolated 24 V DC output for the connected load, with two positive and two negative screw terminals distributing the DC rail.

The input selector on 6EP1333-3BA00 separates the 120 V and 230–500 V source ranges and is moved only while the unit is de-energized. Depending on the selected range, the supply accepts 85–264 V AC or 176–550 V AC at 47–63 Hz before producing its rated output.

Two front switches change how 6EP1333-3BA00 reacts to loading. Switch A chooses the hard single-unit characteristic or the soft characteristic for parallel operation, while switch B selects constant-current behavior or a latching shutdown when overload drives the output below 20 V.

Normal, overload and shutdown conditions are separated on 6EP1333-3BA00 through green, yellow and red LEDs. The colors therefore distinguish available output from a current-limit event and from the latched state.

The housing of 6EP1333-3BA00 snaps vertically onto an EN 60715 DIN rail. A 50 mm space above and below the unit maintains the cooling path for its -25 to +70 °C natural-convection range.

Technical notes
Siemens 6EP1333-3BA00 uses a de-energized input-range selector and separate switches for parallel and overload characteristics. Verify their positions before energizing the connected 24 V load.

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.
When may the input-range selector on 6EP1333-3BA00 be moved?
The selector on 6EP1333-3BA00 may be changed only while the power supply is de-energized; its factory position is 230 V.
Which switch settings identify normal single-unit operation on 6EP1333-3BA00?
The delivery state of 6EP1333-3BA00 has switch A off for the hard single-unit characteristic and switch B off for constant-current overload behavior.
What changes when the output of 6EP1333-3BA00 is adjusted above 24 V?
For 6EP1333-3BA00, output current must be reduced by 4% per additional volt, or allowable ambient temperature reduced by 3 °C per volt.
How do the three LEDs on 6EP1333-3BA00 separate fault conditions?
On 6EP1333-3BA00, green indicates normal output, yellow identifies overload in constant-current mode, and red identifies latching shutdown or remote switch-off.
What must be provided on the line side of 6EP1333-3BA00?
6EP1333-3BA00 requires the documented protective and disconnecting devices, with the protective conductor connected to its PE terminal.
Can two 6EP1333-3BA00 supplies be connected for more output power?
Yes. Two 6EP1333-3BA00 units may be connected in parallel when switch A selects the documented soft characteristic for current sharing.
