Siemens 6EP1-337-3BA00 DC Power Supply Module

Siemens 6EP1-337-3BA00 SITOP PSU100M is a stabilized DC power supply module used in industrial automation to deliver reliable 24 V power for controllers, relays, sensors, and other 24 V loads, typically deployed in panel-mounted SITOP systems. It accepts a single-phase 120/230 V AC input at 50/60 Hz and provides 24 V DC output up to 40 A, equating to a maximum of 960 W of continuous power. This model is part of the SITOP PSU100M family, which Siemens positions as a modular, scalable solution for SIMATIC-based control architectures, enabling straightforward expansion and maintenance within standard control panels and distributed automation racks. Lifecycle information from Siemens identifies a successor, 6EP3337-8SB00-0AY0, highlighting ongoing product evolution and providing a reference point for spare parts, compatibility planning, and long-term availability in automation projects. The 6EP1-337-3BA00 designation identifies the 24 V DC, 40 A variant of PSU100M with the 120/230 V AC input configuration.
