It delivers 91% efficiency at rated load, which keeps heat dissipation low in a crowded cabinet. The input accepts 14 to 32 V DC, so it works on nominal 24 V battery-backed or rectified DC buses without a separate input module. Mounting is standard DIN rail per EN 60715 (35×7.5/15). Clearance of 50 mm above and below the unit is required for natural convection cooling; the side gaps can be zero. The output is galvanically isolated and SELV-rated per EN 60950-1, so it is safe for powering PLCs, I/O racks, sensors, and other 24 V control loads in industrial and commercial panels. The unit is also approved for shipboard use (ABS, DNV GL), which extends its suitability to marine and offshore installations. ## Ratings That Drive the Selection Between +60 °C and +70 °C ambient, the output must be reduced by 2% per Kelvin. At +65 °C, for example, the usable current drops to about 13.5 A. If the panel runs hot, size up or add forced air. Startup is guaranteed from 18 V DC, with derated operation possible down to 14 V DC. This is useful for battery-backed systems where the bus voltage sags under load. The inrush current is limited to an I²t of 0.6 A²·s, which prevents nuisance tripping of upstream breakers. The recommended upstream protection is a 16 A miniature circuit breaker, characteristic B or C. The unit itself has an internal non-accessible 25 A fuse with a breaking capacity of 300 A, so it can handle a hard output short without cascading. Approvals include cULus (UL 508, CSA C22.2 No. 107.1), CE, EAC, and DNV GL. The UL file number is E197259. No ATEX or IECEx certification — this is not a hazardous-location power supply. For a standard control panel or marine installation, the existing approvals cover the regulatory scope. ## Terminal and Wiring Notes Output terminals (+, -) are also screw terminals, same wire range. A separate signaling contact terminal block is provided for remote monitoring. All terminals are sized for standard panel wiring; no special tools needed. The unit can be bridged with a buffer module if ride-through during line dips is required. That is an accessory, not included, but the capability is built into the design.","metaTitle":"Siemens 6EP3124-0TA00-0AY0 Power Supply, 15 A, 24 VDC, DIN R","metaDescription":"Siemens 6EP3124-0TA00-0AY0 power supply, 15 A rated at 24 VDC, 91% efficiency.
