The SITOP PSU100S 6EP1323-2BA00 is a 168W single-phase power supply that stands out for its output voltage: 12VDC rather than the far more common 24V. At 14A continuous, it serves automation panels with a 12V power bus — DC motor controls, solenoid valves, legacy relay logic, and specialized industrial lighting — without the cost and panel space of a separate 24V-to-12V converter stage.

Wide-Range Input and Extra Power

The auto-ranging input accepts any single-phase AC supply from 85 to 264V, 47-63Hz, covering every global mains standard without manual voltage selection. The Extra Power feature temporarily delivers 150% of rated current — up to 21A — for 5 seconds each minute, enough headroom to clear downstream fuses on a branch with a momentary fault or to ride through the inrush period when multiple DC motors start simultaneously. Continuous overload at 120% (16.8A) is supported up to 45°C ambient.

Protection and Monitoring

A green "12V OK" LED and a floating relay contact (NO, rated 60VDC/0.3A) provide local and remote output status. The output is galvanically isolated (SELV), short-circuit proof with constant-current limiting, and protected against overvoltage. Mains buffering holds the output for at least 20ms at nominal input — enough to ride through most grid transients. The module occupies 70mm of DIN rail width and operates from -25°C to +70°C with natural convection cooling.
