It accepts 120 V or 230 V input (selectable via the two rated ranges: 85–132 V AC and 170–264 V AC) at 47–63 Hz. The output voltage is adjustable from 22.8 V to 28 V via a trim pot, which is useful for compensating line drops or matching a specific load voltage tolerance. The unit snaps onto a standard DIN rail per EN 60715 (35×7.5/15 mm profile) — no drilling, no backplate. Clearance requirements: 50 mm above and 50 mm below for natural convection cooling; zero clearance on the left and right sides, so it can be packed tight against adjacent modules. A green LED on the front panel indicates 24 V OK — useful for a quick visual check during commissioning or fault isolation. The startup delay is under 0.1 s, and the typical voltage rise time is 50 ms, so downstream loads see a clean power-up sequence. ## Sourcing and lifecycle — active, quoted to order Approvals include CE marking and marine type approvals from ABS and GL, so it is accepted in European and maritime installations. The unit is Class I (protective earth required) and carries CB certification. EMC compliance covers both emission (EN 55022 Class B) and immunity (EN 61000-6-2), making it suitable for residential and light-industrial environments without external filtering. ## Integration notes — wiring and thermal The 50 mm top and bottom clearance is mandatory for natural convection; if the panel has forced airflow, you may reduce it, but the datasheet ratings assume free air. Ambient operating range is 0–60 °C, storage/transport from –40 to +85 °C. MTBF at 40 °C is 1,443,606 hours — roughly 165 years, which is typical for a well-designed industrial supply and gives confidence for long-life installations. ## Protection and behavior under fault Current limitation is set at 12.5–13.5 A, meaning the supply will fold back rather than shut down on overload — it can start capacitive loads or drive short-duration inrush without nuisance tripping. The maximum I²t is 3.3 A²·s, which helps with fuse coordination downstream. On/off behavior shows a 4% overshoot on the output voltage, within acceptable limits for most 24 V loads. Mains buffering is specified at 93 V and 187 V input — the hold-up time is not given numerically, but the unit is designed to ride through brief line dips. Galvanic isolation provides SELV output per EN 60950-1 and EN 50178, so it is safe for direct connection to control circuits and touch-safe terminals.","metaTitle":"Siemens 6EP1334-2BA01 SITOP PSU100M 24V 2.5A, 1-phase AC","metaDescription":"Siemens 6EP1334-2BA01 SITOP PSU100M power supply, 24 V DC / 2.5 A, 1-phase AC input 120/230 V, DIN rail mount, CE, marine approved, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["DIN Rail Power Supplies"],"specifications":{"Top":"50 mm","Left":"0 mm","Note":"with natural convection","Input":"1-phase AC","Right":"0 mm","title":"6EP1334-2BA01","Bottom":"50 mm","Output":"L+, M: 2 screw terminals each for 0.5 ... 2.5 mm²","1 at AC":"85 ... 132 V","2 at AC":"170 ... 264 V","CE mark":"Yes","Maximum":"3.5 mA","Typical":"0.8 mA","I2t, max.":"3.3 A²·s","CB approval":"Yes","description":"SITOP smart 240 W Stabilized power supply input: 120/230 V AC, output: DC 24 V/10 A Version with PFC","Installation":"Snaps onto DIN rail EN 60715 35x7.5/15","Supply input":"L, N, PE: 1 screw terminal each for 0.5 ... 2.5 mm² single-core/finely stranded","Current range":"0 ... 12 A","During Storage":"-40 ... +85 °C","MTBF at 40 °C":"1 443 606 h","Noise immunity":"EN 61000-6-2","Status display":"Green LED for 24 V OK","Mains buffering":"at Vin = 93/187 V","Marine approval":"ABS, GL","On/off behavior":"Overshoot of Vout approx. 4 %","Weight, approx.":"0.8 kg","lifecycle_stage":"current","Adjustment range":"22.8 ... 28 V","During Operation":"0 ... 60 °C","During Transport":"-40 ... +85 °C","Protection class":"Class I","Rated line range":"47 ... 63 Hz","Wide-range input":"No","Other Information":"Specifications at rated input voltage and ambient temperature +25 °C (unless otherwise specified)","Current limitation":"12.5 ... 13.5 A","Galvanic Isolation":"Safety extra-low output voltage Uout acc. to EN 60950-1 and EN 50178","Voltage rise, typ.":"50 ms","1 at AC rated value":"120 V","2 at AC rated value":"230 V","Startup delay, max.":"0.1 s","Emitted interference":"EN 55022 Class B","Explosion protection":"ATEX (EX) II 3G Ex nA II T4; UL 1604 Class I, Div. 2, Group ABCD","Connection technology":"screw-type terminals","Rated voltage Vout DC":"24 V","UL/cUL (CSA) approval":"cULus-Listed (UL 508, CSA C22.2 No. 107.1), File E197259, cCSAus (CSA C22.2 No. 60950-1, UL 60950-1, UL 1604)","Built-in incoming fuse":"T 6.3 A/250 V (not accessible)","Depth Of The Enclosure":"125 mm","Output voltage setting":"via potentiometer","Overvoltage resistance":"2.3 × Vin rated, 1.3 ms","Rated line frequency 1":"50 Hz","Rated line frequency 2":"60 Hz","Width Of The Enclosure":"70 mm","Height Of The Enclosure":"125 mm","Short-circuit protection":"Constant current characteristic","Total tolerance, static ±":"3 %","Primary/secondary isolation":"Yes","Supply harmonics limitation":"EN 61000-3-2","at rated input voltage 120 V":"4.1 A","at rated input voltage 230 V":"2 A","Output overvoltage protection":"< 33 V","Supplied Active Power Typical":"288 W","Rated current value Iout rated":"10 A","Static load balancing, approx.":"0.5 %","Degree of protection (EN 60529)":"IP20","Residual ripple peak-peak, max.":"150 mV","Residual ripple peak-peak, typ.":"50 mV","At Short-Circuit During Operation":"200 ms","Static mains compensation, approx.":"0.1 %","Mains buffering at Iout rated, min.":"20 ms; at Vin = 93/187 V","Humidity class according to EN 60721":"Climate class 3K3, 5 … 95% no condensation","Load step setting time 100 to 50%, typ.":"0.2 ms","Load step setting time 50 to 100%, typ.":"0.2 ms","On Short-Circuiting During The Start-Up":"100 ms","At Short-Circuit During Operation Typical":"33 A","Product Function Output Voltage Adjustable":"Yes","Property Of The Output Short-Circuit Proof":"Yes","Spikes peak-peak, max.
