DDP400 Sealed AC/DC Power Supplies

The DDP400 sealed AC/DC power supplies are potted and offer IP67 ingress protection. They come in standard output voltages of 12, 24, 36 and 48 VDC, with auxiliary 12V fan and 5V stand-by outputs.

The series provide a steady 400 W of regulated DC power through the full 90 to 264 VAC input range. A 3.27” x 8.34” x 1.65” form factor, enable designers to integrate it into 1U applications.
