Input accepts 85–264 VAC (47–63 Hz) or 99–275 VDC. The single output is SELV per EN 60950-1. Snaps onto DIN rail EN 60715 35x7.5/15 — standard 35 mm profile — and occupies a 45 mm top clearance plus 45 mm below for airflow and wiring. No side clearance needed (0 mm left and right), so it packs tight against adjacent devices on the rail. Push-in terminals at input (0.5–4 mm²) and output (0.5–2.5 mm²) speed wiring; no screwdriver needed for the power connections. ## Thermal Reality and Derating Rated full output up to +60 °C ambient. Above that, derate 1.5 % per Kelvin up to +70 °C. ## Protection and Approvals UL 508 listed (cULus, file E197259) and CSA C22.2 No. 107.1, plus cCSAus to UL 60950-1 / CSA 60950-1. CE marked and EAC approved. The output qualifies as NEC Class 2 per UL 1310, which simplifies wiring in plenum or raceway runs. Input protection calls for a 4 A C-curve or 6 A B/C breaker, or a Siemens 3RV2011-1EA10 set to 4 A. Current production — no end-of-life notice. No official successor exists; the part is active.","metaTitle":"Siemens 6EP3333-7LB00-0AX0 Power Supply, 3.7 A, 24 VDC","metaDescription":"Siemens 6EP3333-7LB00-0AX0 SITOP power supply, 3.7 A rated output, 24 VDC, 85-264 VAC / 99-275 VDC input, IP20, DIN rail mount, UL/CSA/CE approved, current production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["DIN Rail Power Supplies"],"specifications":{"Top":"45 mm","ATEX":"No","Left":"0 mm","IECEx":"No","Right":"0 mm","at DC":"99 ... 275 V","title":"6EP3333-7LB00-0AX0","Bottom":"45 mm","C-Tick":"No","DNV GL":"No","Maximum":"3.5 mA","Typical":"3.7 A","At Input":"L1/+, L2/N/-, PE:PushIn for 0.5 ... 4 mm² single-core/finely stranded","At Output":"+1, +2, -1, -2, -3: PushIn for 0.5 ... 2.5 mm²","CE marking":"Yes","NEC Class 2":"Yes; acc. to UL 60950-1/UL 1310, File E151273","Rated Range":"0 ... 3.7 A; +60 ... +70 °C: Derating 1.5%/K","Rated Value":"3.7 A","UL approval":"Yes; cULus-Listed (UL 508, CSA C22.2 No. 107.1), File E197259; cCSAus (CSA C22.2 No. 60950-1, UL 60950-1)","description":"SITOP PSU6200 3.7 A NEC class II Stabilized power supply Input: 120 - 230 V AC, (120 - 240 V DC) Output: 24 V DC/3.7 A","CSA approval":"Yes; cULus-Listed (UL 508, CSA C22.2 No. 107.1), File E197259; cCSAus (CSA C22.2 No. 60950-1, UL 60950-1)","EAC approval":"Yes","1 Rated Value":"50 Hz","2 Rated Value":"60 Hz","In The Feeder":"Circuit breaker 4 A characteristic C or 6 A characteristic B/C or circuit breaker 3RV2011-1EA10 (setting 4 A) or 3RV2711-1ED10 (UL 489)","Initial Value":"85 V","During Storage":"-40 ... +85 °C","Line Frequency":"47 ... 63 Hz","FM registration":"No","lifecycle_stage":"current","During Operation":"-30 ... +70 °C; with natural convection a monotonically increasing start-up from -25 °C, safe start-up from -40 °C","During Transport":"-40 ... +85 °C","Fastening Method":"Snaps onto DIN rail EN 60715 35x7.5/15","Full-Scale Value":"264 V","Number Of Outputs":"1","Other Information":"Specifications at rated input voltage and ambient temperature +25 °C (unless otherwise specified)","ULhazloc approval":"No","Galvanic Isolation":"Safety extra low output voltage Vout according to EN 60950-1","Maximum Rated Value":"240 V","Minimum Rated Value":"120 V","protection class IP":"IP20","Fuse Protection Type":"3.15 A","Bridging Of Equipment":"No","Efficiency In Percent":"89.3 %","Shipbuilding Approval":"ABS; in process: DNV","Depth Of The Enclosure":"125 mm","Electrical Accessories":"Buffer module, redundancy module","For Auxiliary Contacts":"13, 14 (alarm signal): 1 push-in terminal each for 0.2 ... 1.5 mm²","Mechanical Accessories":"Identification labels SIMATIC ET 200SP 6ES7193-6LF30-0AW0","Response Delay Maximum":"0.5 s","Width Of The Enclosure":"35 mm","Height Of The Enclosure":"135 mm","Voltage Curve At Output":"Controlled, isolated DC voltage","For Emitted Interference":"EN 55022 Class B","Nippon Kaiji Kyokai (NK)":"No","Type Of Signal At Output":"Electronic contact (NO contact, contact rating 30 V DC/0.1 A) for DC O.K.","Adjustable Output Voltage":"24 ... 28 V","For Interference Immunity":"EN 61000-6-2","Load Step 10 To 90% Typical":"2 ms","Load Step 90 To 10% Typical":"2 ms","cCSAus, Class 1, Division 2":"No","at rated input voltage 120 V":"1.5 A","at rated input voltage 240 V":"0.9 A","Supplied Active Power Typical":"89 W","Type Of Electrical Connection":"Push-in terminals","at output 1 at DC rated value":"24 V","For Mains Harmonics Limitation":"EN 61000-3-2","Type Of Output Voltage Setting":"via potentiometer; max. 89 W (106 W up to 45°C)","Overvoltage Overload Capability":"300 V AC for 30 s","Design Of Input Wide Range Input":"Yes","During NO-Load Operation Maximum":"2.2 W","Regulatory Compliance Mark (RCM)":"No","Type Of The Power Supply Network":"1-phase AC or DC","output voltage at DC rated value":"24 V","Lloyds Register of Shipping (LRS)":"No","Design Of Short-Circuit Protection":"Shutdown and periodic restart attempts","On Slow Fluctuation Of Ohm Loading":"0.3 %","Operating Resource Protection Class":"Class I","Design Of The Overvoltage Protection":"< 32 V","Display Version For Normal Operation":"Green LED for 24 V OK","On Slow Fluctuation Of Input Voltage":"0.2 %","At Short-Circuit During Operation Typical":"3.7 A","French marine classification society (BV)":"No","Relative Overall Tolerance Of The Voltage":"3 %","Operating Condition Of The Mains Buffering":"at Vin = 240 V","Product Function Output Voltage Adjustable":"Yes","Property Of The Output Short-Circuit Proof":"Yes","Galvanic Isolation Between Input And Output":"Yes","American Bureau of Shipping Europe Ltd.
