It's built for industrial control panels where you need a stable DC bus from a single-phase AC line — think PLC racks, DC motor brakes, or sensor power rails. It provides safety extra-low voltage (SELV) output per EN 60950-1, so the DC side is touch-safe and can feed circuits that need galvanic separation from the mains. Efficiency sits at 86% at rated load, which keeps heat dissipation manageable in a sealed enclosure — you won't need to oversize the cabinet ventilation just for this unit. The 12.5 A rating is continuous at 25 °C ambient, but the unit derates 2.5% per Kelvin above 50 °C up to 70 °C. That means at 60 °C you're looking at about 9.4 A available — plan your load budget around the derated figure if the panel runs hot. Input accepts 85–264 V AC at 47–63 Hz, covering 100–240 V nominal ranges worldwide. The wide input tolerance means it handles brownouts down to 85 V without dropping the output. It's rated IP20, so it belongs inside a panel — not on a washdown line or outdoors. Mount it on a wall or DIN rail (fastening method is wall mounting; adapters for DIN rail are common in the family). Operating temperature range is -10 to +70 °C with forced convection (a fan). Without active airflow, the upper limit drops — so if your panel relies on natural convection, you'll need to derate further or add a fan. UL and CSA approvals are in place (cULus-Listed to UL 508 and CSA C22.2 No. 107.1, plus cURus to UL 60950-1 and CSA C22.2 No. 60950-1), so it's accepted for North American panels without a special inspection sticker. CE and EAC markings cover European and Eurasian Economic Union markets. No ATEX or IECEx certification — not rated for explosive atmospheres. ## What to watch when wiring Input terminals (L, N, PE) accept 0.5 to 1.3 mm² single-core or finely stranded wire — one screw terminal per connection. Output terminals (+, -) give you two screw terminals each for the same wire range, handy for daisy-chaining loads without a separate distribution block. Siemens recommends a 10 A characteristic C or 16 A characteristic B miniature circuit breaker in the feeder. Internal fuse protection is built in, but the upstream breaker is still needed for the wiring. The unit supports bridging of equipment (paralleling outputs) if you need more current — but watch the derating and total system limits.","metaTitle":"Siemens 6EP1334-1LD00 Power Supply, 12.5 A, 86% Efficiency","metaDescription":"Siemens 6EP1334-1LD00 power supply, 12.5 A rated output, 86% efficiency, SELV galvanic isolation, UL/CSA listed, IP20, current lifecycle stage.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Power Supplies"],"specifications":{"Top":"20 mm","ATEX":"No","Left":"20 mm","IECEx":"No","Right":"20 mm","title":"6EP1334-1LD00","Bottom":"0 mm","DNV GL":"No","Maximum":"3.5 mA","Typical":"1 mA","At Input":"L, N, PE: 1 screw terminal each for 0.5 ... 1.3 mm² single-core/finely stranded","At Output":"+, -: 2 screw terminals each for 0.5 ... 1.3 mm²","CE marking":"Yes","NEC Class 2":"No","Rated Range":"0 ... 12.5 A; +50 ... +70 °C: Derating 2.5%/K","Rated Value":"12.5 A","UL approval":"Yes; cULus-Listed (UL 508, CSA C22.2 No. 107.1), File E197259; cURus (UL 60950-1, CSA C22.2 No. 60950-1), File E151273","description":"********** spare part ********* PSU100D 24 V/12.5 A stabilized power supply input: 100-240 V AC output: 24 V DC/12.5 A","CSA approval":"Yes; cULus-Listed (UL 508, CSA C22.2 No. 107.1), File E197259; cURus (UL 60950-1, CSA C22.2 No. 60950-1), File E151273","EAC approval":"Yes","1 Rated Value":"50 Hz","2 Rated Value":"60 Hz","In The Feeder":"Recommended miniature circuit breaker: from 10 A characteristic C or from 16 A characteristic B","Initial Value":"85 V","During Storage":"-40 ... +85 °C","Line Frequency":"47 ... 63 Hz","FM registration":"No","lifecycle_stage":"current","During Operation":"-10 ... +70 °C; with forced convection (ventilator)","During Transport":"-40 ... +85 °C","Fastening Method":"Wall mounting","Full-Scale Value":"264 V","I2t value maximum":"1.1 A²·s","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":"100 V","protection class IP":"IP20","Fuse Protection Type":"internal","Bridging Of Equipment":"Yes","Efficiency In Percent":"86 %","Depth Of The Enclosure":"41 mm","Response Delay Maximum":"1 s","Width Of The Enclosure":"105 mm","Height Of The Enclosure":"199 mm","Voltage Curve At Output":"Controlled, isolated DC voltage","For Emitted Interference":"EN 55022 Class B","Nippon Kaiji Kyokai (NK)":"No","Adjustable Output Voltage":"22 ... 28 V","For Interference Immunity":"EN 61000-6-2","cCSAus, Class 1, Division 2":"No","at rated input voltage 100 V":"4 A","at rated input voltage 240 V":"2 A","Supplied Active Power Typical":"300 W","Type Of Electrical Connection":"screw-type 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","Design Of Input Wide Range Input":"Yes","Type Of The Power Supply Network":"1-phase AC","output voltage at DC rated value":"24 V","Lloyds Register of Shipping (LRS)":"No","Design Of Short-Circuit Protection":"Electronic shutdown, automatic restart","On Slow Fluctuation Of Ohm Loading":"0.5 %","Operating Resource Protection Class":"Class I","Design Of The Overvoltage Protection":"< 35 V","Display Version For Normal Operation":"Green LED for 24 V OK","On Slow Fluctuation Of Input Voltage":"0.5 %","French marine classification society (BV)":"No","Relative Overall Tolerance Of The Voltage":"2 %","Operating Condition Of The Mains Buffering":"at Vin = 115/230 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.
