Product Overview
The Siemens 6EP1332-2BA20 is a stabilized power supply from the SITOP PSU100S series. It delivers 24 V DC output at 2.5 A from a 1-phase AC input (120/230 V AC with automatic range selection). This module provides a controlled, isolated DC voltage with adjustable output from 22.8 to 28 V. Its compact design (32.5 x 125 x 120 mm) snaps onto a DIN rail, making it ideal for control cabinets.

Industry Applications
The Siemens 6EP1332-2BA20 powers PLC systems, sensors, and actuators in industrial automation. Its 20 ms buffering time bridges short mains interruptions, preventing data loss. The relay contact signals "24 V OK" for remote monitoring. With marine approvals (BV, DNV) and EN 55022 Class B emission compliance, it suits both factory floors and marine control panels.
Reliability & Cost Benefits
With an MTBF exceeding 1.8 million hours and 85% efficiency, the Siemens 6EP1332-2BA20 reduces energy costs and unplanned downtime. Overvoltage protection (<33 V) and short-circuit proof output safeguard connected equipment. Its global warming potential (321.3 kg CO2 eq) demonstrates lifecycle transparency for sustainable procurement.
Installation & Mounting
Mount the Siemens 6EP1332-2BA20 on a DIN rail EN 60715 35x7.5/15. Use screw terminals: input L, N, PE (0.5–2.5 mm²), output +, - (two terminals each), and alarm contacts. Maintain 50 mm clearance above and below for natural convection. Operating temperature range: -25 to +70°C.
Selection Guide & Purchasing Advice
Verify input voltage and load current before ordering. The Siemens 6EP1332-2BA20 supports parallel operation of up to two units for higher power. For genuine parts and fast shipping, choose ubest101 as your reliable industrial automation supplier.
