Siemens 6EP13325BA20 DIN Rail Power Supply
Overview
Selection of any DIN rail-mounted power supply demands verification of mechanical envelope, thermal derating behavior, and hold-up time—parameters not fully resolved in the catalog fields for 6EP13325BA20. The data confirms a single-output 24 VDC unit with AC-or-DC input flexibility (85–264 VAC range), rated 3.7 A maximum output, and 87% efficiency. Safety certifications cover CB, cCSAus, CE, CSA, cUL, cULus, and UL for industrial and ITE environments. The "PSU100C" family name visible in alternate listings suggests this is a compact regulated unit; confirm against the Siemens datasheet for physical mounting dimensions and output ripple specification.

Verification required before selection
The following electrical and mechanical parameters are not present in the supplied catalog fields and must be confirmed against the official Siemens datasheet before finalizing a design or procurement decision:
- Physical dimensions (width, height, depth) and DIN rail mounting clip geometry
- Operating temperature range and derating curve above 25 °C
- Output ripple and noise (mVpp specification)
- Hold-up time at nominal input and rated load
- Inrush current limit and cold-start behavior
- Overload and short-circuit protection mode (constant current, foldback, latch)
- EMC / EMI class (conducted emissions level)
- Input fuse rating or required upstream protection
Integration / Installation Notes
The product carries IP20 rating, meaning it is protected against solid objects >12.5 mm and is not protected against water. Deployment in an enclosure or cabinet is implied for industrial environments. DIN rail mounting is standard per the category path; however, the specific rail profile (TH35 top-hat or G32) and required clearance for ventilation are not specified in the supplied fields and must be verified with the datasheet.
The universal AC/DC input range supports both mains operation and DC bus backup scenarios; however, no explicit DC current rating is listed in the provided data.
Selection / Substitution Guidance
The 6EP13325BA20 falls within a family of PSU100C units differentiated primarily by current rating. Substituting with a higher or lower current variant is feasible only if mechanical dimensions, thermal derating, and protection characteristics are verified in the target application's specific environment. The catalog similarity scores reflect shared spec keys and are not indicators of functional equivalence in a given circuit.

Why these are similar:
- 6EP13325BA10: Shares the same PSU100C family, identical input voltage ranges (AC 85–264 V, DC 110–300 V), same certifications and IP20/Adjustable feature set. Output current is higher at 4 A (96 W); the physical package may differ. Confirm dimensions before substitution.
- 6EP13325BA00: Same PSU100C family, identical input flexibility, same certifications. Output current is lower at 2.5 A (60 W). Drop-in substitution only if load does not exceed 60 W and thermal margins are acceptable.
- 6EP13322BA20: Identical approvals, features, and output specs (24 V, 2.5 A). However, input accepts only AC (170–264 V or 85–132 V) and lacks the DC input range present in the primary. Not suitable for DC bus or battery-backed applications.
FAQ
Q: Can 6EP13325BA20 operate from a 120 VDC supply? The DC input range listed is 110–300 VDC. A 120 VDC source falls within this window, but verify inrush current behavior and confirm that the input is rated for DC operation under the specific application's ambient conditions.
Q: What is the maximum ambient operating temperature? The catalog fields do not include an operating temperature range or derating specification. The Siemens datasheet must be consulted; comparable units in the PSU100C series commonly derate above 50–60 °C.
Q: Is 6EP13325BA10 a direct mechanical drop-in for 6EP13325BA20? Both share the same PSU100C family and identical input/certification parameters, but the 4 A rating of BA10 suggests a higher-power variant. Physical dimensions may differ. Verify enclosure fit and thermal output before substitution.
