It accepts a wide DC input range of 300 to 900 VDC, making it suitable for intermediate DC bus or high-voltage DC rail applications in industrial control panels. Efficiency hits 95%, which keeps heat dissipation low in a 125 mm deep enclosure that snaps onto standard DIN rail EN 60715 35x7.5/15. The IP20 rating means it's for clean, indoor cabinet mounting only. The 20 A rating holds across a 0 to 20 A range, but above +60 °C ambient you derate 5.5% per Kelvin up to +70 °C. That's a hard rule for panel builders: if your cabinet runs hot, you lose over half an amp per degree past 60. Startup requires at least 340 VDC, with derating needed between 300-400 VDC and 824-900 VDC — so don't assume full output at the low end of the input range. The unit includes built-in fuse protection with a 20 kA cut-off capacity and an I²t maximum of 0.02 A²·s, which simplifies branch circuit coordination. Galvanic isolation provides protective extra-low voltage (PELV) output per EN 60950-1 and EN 50178, so it's safe for direct connection to PLC I/O and field sensors. Snaps onto DIN rail EN 60715 35x7.5/15. Clearance requirements: 50 mm top and bottom, zero on left and right — so you can butt multiple units side-by-side. Input connections are single screw terminals per pole (+, -, PE) accepting 0.2-6 mm² single-core or 0.2-4 mm² finely stranded. Output uses dual screw terminals per pole for easy daisy-chaining. Alarm signal terminals take 0.14-1.5 mm².","metaTitle":"Siemens 6EP1536-3AA00 DC Power Supply, 20 A, 95% Efficiency","metaDescription":"Siemens 6EP1536-3AA00 DC power supply, 20 A rated, 95% efficiency, 300-900 VDC input, UL/cUL listed, DNV GL approved, IP20, DIN rail mount.
