Siemens 6EP1 332-1SH31 Power Supply

Siemens SITOP Power 3.5 24 V DC power supply, model 6EP1332-1SH31 (also catalogued as 6EP1 332-1SH31), a compact DIN-rail mounted source designed to power 24 V DC loads in S7-200 automation systems. It provides a regulated 24 V DC output at up to 3.5 A for PLCs, encoders, and sensors, with input options for 120 V or 230 V single-phase AC and a selectable input voltage range of 93–132 V (120 V) or 187–264 V (230 V) at 50/60 Hz. The unit draws about 1.65 A at 120 V or 0.95 A at 230 V, and includes protective measures such as an integrated line-side fuse (T 2.5 A/250 V, not accessible) and an inrush current limiter rated at under 33 A with a response time under 3 ms at 230 V. It offers mains buffering of more than 20 ms at 187 V to help ride through short disturbances, and mounts by snapping onto a DIN EN 50022 35×15 mm profile. This SITOP Power 3.5 device is designed for simple, robust 24 V loads in industrial cabinets and is commonly used to supply the S7-200 controller family along with peripheral devices requiring a stable 24 V supply.
