The Siemens 6EP1436-3BA10 power supply is rated for a 400-500 VAC input at 47-63 Hz, delivering 20 A continuously with 93% efficiency. The unit carries UL/cULus listing under UL 508 and CSA C22.2 No. 107.1, plus EAC and CE marks.
Input and Output Ratings
Rated input voltage range is 400-500 VAC, line frequency 47-63 Hz, with a maximum rated value of 500 V and a full-scale value of 575 V. The output is rated at 20 A over a 0-20 A range; above +60 °C derate at 3%/K up to +70 °C. The I²t value is 0.8 A²·s maximum. At rated input and 25 °C ambient, typical no-load draw is 0.9 mA, maximum 3.5 mA. Feeder protection requires a 3-pole miniature circuit breaker 6-16 A characteristic C, or a Siemens 3RV2011-1DA10 (setting 3 A) or 3RV2711-1DD10 (UL 489).
Protection class is IP20. The unit mounts via snap-on to DIN rail EN 60715 35x7.5/15. Clearance required: top 50 mm, bottom 50 mm, left 0 mm, right 0 mm.
