Schneider Electric Rectified & Filtered Power Supply DIN Rail Power Supply, 207 → 253 V ac, 360 → 440 V

Filtered, rectified power supplies are built using a security transformer equipped with a bridge rectifier and filter capacitors.
With no regulation, rectified power supplies provide a non-regulated voltage sensitive to variations in line supply and load. They can only be used on good quality line supplies where fluctuations are limited to -10 %… + 10 % of the nominal value.
These supplies are connected between phase and neutral or between two phases, filtered and rectified. They are designed for direct mounting on a DIN rail.
