The Siemens 6EP1332-2BA20 is a SITOP PSU100C power supply delivering a rated output of 2.5 A at 24 V DC, with automatic range selection on the AC input side covering 85–132 V and 170–264 V at 47–63 Hz. The output is safety extra-low voltage (SELV) per EN 60950-1 and EN 50178, so it can directly power PLCs, sensors, and 24 V DC control circuits without additional isolation.
The rated current of 2.5 A holds up to +45 °C ambient; above that, derate 3 % per K up to +70 °C. At 40 °C the MTBF is over 1.8 million hours, which translates to low expected failure rates in continuous-duty applications like conveyor controls or pump stations. The recommended upstream protection is a miniature circuit breaker rated 3 A, characteristic C. The internal fuse is a T 3.15 A / 250 V type, not user-accessible, so the MCB is your primary overcurrent device. Input inrush is limited to 3.5 A maximum, typically 0.4 A, which avoids nuisance tripping of the feeder breaker during power-up.
This unit carries cULus listing under UL 508 and CSA C22.2 No. 107.1 (File E197259), plus cCSAus to CSA C22.2 No. 60950-1 and UL 60950-1. CE and EAC marks are present. It is not ATEX or IECEx rated, and not NEC Class 2. DNV GL marine approval is confirmed, so it suits shipboard or offshore installations where classification society certification is required.
