More Information

Overview Manuals Input Stage DC Regulation Fault Response Thermal Fit

Features:

  • A wide-range single-phase input feeds a controlled and electrically isolated DC output.
  • The 24 V rail can be adjusted by potentiometer while a green LED confirms normal output status.
  • Electronic short-circuit shutdown restarts automatically after the fault condition clears.
Siemens 6EP1332-1LD00 provides the 3.1 A member of the wall-mounted SITOP PSU100D power-supply arrangement.

Input buffering bridges a brief mains interruption before the connected 24 V load loses the regulated source.

Output derating ties the available current to ambient temperature, while parallel operation permits two supplies to share an increased load.

The Siemens 6EP1332-1LD00 SITOP PSU100D 24 V DC 3.1 A Stabilized Power Supply may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Preparing the single-phase source before conversion

  • Wide-Range Entry: One AC input stage accepts the documented voltage span without manual range switching.
  • Internal Fuse: A built-in incoming fuse protects the supply's internal mains path.
  • External Breaker: The upstream circuit uses the documented breaker rating and characteristic.
  • Buffer Interval: Stored energy maintains the rated output briefly when the mains source drops out.

Holding the control rail within its set range

  • Isolated Output: The controlled DC rail is galvanically separated from the mains input.
  • Potentiometer Setpoint: The front adjustment changes the output within the documented 22–28 V range.
  • Load Response: Closed-loop regulation limits the voltage change when the connected current steps.
  • Green Indicator: The 24 V OK LED gives a direct visual check of output presence.

Managing overload and short-circuit conditions

  • Current Limit: The output control restricts current before a sustained overload escalates.
  • Electronic Shutdown: A short circuit causes the DC output stage to switch off electronically.
  • Automatic Restart: The supply attempts to restore the rail after the short-circuit condition is removed.
  • Parallel Pair: No more than two units are specified for increased output performance.

Maintaining output capacity with natural convection

  • Wall Mounting: The enclosure attaches to a flat mounting surface rather than a cap rail.
  • Air Cooling: Natural convection carries heat away without a built-in fan.
  • Full Current: The complete 3.1 A rating applies through the documented 50 °C boundary.
  • High-Temperature Derating: Available current is reduced for operation up to the 70 °C maximum.
Description
Siemens 6EP1332-1LD00 is a SITOP PSU100D stabilized power supply that converts a single-phase AC source into isolated 24 V DC control power. Its rated output supplies 3.1 A to connected DC loads.

On the mains side, 6EP1332-1LD00 accepts a wide input range around the 100–240 V AC rating. An internal input fuse and documented upstream breaker choices protect that path, while the supply retains the rated output briefly during a mains interruption.

The output of 6EP1332-1LD00 is adjustable by potentiometer and a green LED indicates the 24 V OK condition. Static regulation keeps source and load changes within the specified output tolerance rather than passing line variation directly to the DC rail.

During an output short circuit, 6EP1332-1LD00 uses electronic shutdown followed by automatic restart. Two units may be paralleled for increased output, and the normal load rating is reduced when the ambient temperature rises above the full-current range.

Screw terminals connect line, neutral, protective earth, positive output, and negative output on 6EP1332-1LD00. The IP20 enclosure is intended for wall mounting with natural-convection cooling rather than cap-rail or S7-300 rail installation.

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.
Can Siemens 6EP1332-1LD00 be installed on a DIN rail?
No. Siemens 6EP1332-1LD00 is documented for wall mounting, while cap-rail and S7-300 rail mounting are not specified.
What happens after an output short circuit on 6EP1332-1LD00?
Siemens 6EP1332-1LD00 shuts the output down electronically and restarts automatically after the short-circuit condition clears.
May two 6EP1332-1LD00 supplies be connected in parallel?
Yes. The documented enhanced-performance arrangement permits two 6EP1332-1LD00 units in parallel, not an unrestricted number of supplies.
Which upstream breaker is documented for 6EP1332-1LD00?
The mains input of 6EP1332-1LD00 is documented with a breaker from 10 A characteristic C or from 16 A characteristic B.
How much current remains available above 50 °C for 6EP1332-1LD00?
The full 3.1 A rating of 6EP1332-1LD00 applies through 50 °C; operation through 70 °C is limited to 1.5 A.
How can I confirm that 6EP1332-1LD00 is producing the DC rail?
A green 24 V OK LED on 6EP1332-1LD00 indicates the documented output-present condition; the connected load voltage should still be verified at the terminals.
