Siemens 6EP3344-7SB00-3AX0 SITOP PSU6200 48V/5A Power Supply

The Siemens 6EP3344-7SB00-3AX0 is a SITOP PSU6200 power supply that converts a 120-240 V AC (or 110-240 V DC) input into a stabilized 48 V DC output rated 5 A, 6 A up to 45 degrees C. It provides a diagnostic contact for DC O.K. status and reaches 93.9% efficiency at 240 W typical supplied power.

Selection Notes

At 48 V this PSU6200 variant serves telecom-style or motor-brake circuits that standardize on a 48 V rail instead of 24 V, and the 5 A rating (6 A up to 45 degrees C) with 150% overload capability for up to 5 s/min covers brief inrush from relays or brake coils. The diagnostic contact reports DC O.K. status the same way the 12 V and 24 V PSU6200 models do, so panel monitoring wiring stays consistent across voltage variants; use a 24 V PSU6200 model instead when the downstream I/O and PLC hardware is standard 24 V DC.

Applications

Fits 48 V DC circuits such as electromechanical brake coils, telecom-derived control loops, or legacy equipment standardized on a 48 V bus, with a wired DC O.K. signal for panel monitoring.
