DDP400-US24-SC-2

The Enedo DDP400-US24-SC-2 is a sealed, full potted, compact, high efficiency, IEC class II, AC-DC power supplies.

It provides a steady 400 W of regulated DC power and can be operated over the full 90 to 264 VAC input voltage range in a (4 x 9 x 2)” form factor.

By converting energy at a typical 94% efficiency, the DDP400-US24-SC-2 generates less heat facilitating thermal management in space constrained environments, resulting in very high reliability.

It comes in a 24 VDC, standard output voltage.

The sealed and full potted package allows an IP66/67 ingress protection index and can be installed in contact with thermo-conductive part of the system so to transfer heat by conduction, therefore, enhancing performances.

Input and output cables, in addition to meeting the specific isolation requirements of the IEC Class II, are UV resistant for outdoor installation.

When conduction cooled, or convection cooled with its optional heat sink assembled, the SC series can deliver full output power from -20 to 50 °C. It can operate up to 70 °C with derating and is capable to start up from – 30 °C and from – 40 °C with reduced start up load.

Protection features do include fuse on each AC lines, input under-voltage lockout (IUV), output over-current (OC), output short-circuit (SC), output over-voltage (OV) and over-temperature (OT).

The DDP400-US24-SC-2 complies with UL/IEC 60950-1 and 62368-1 standards, meets the EN55032 EMC limits of Class B for conducted and radiated emissions as well as the IEC/EN 61000-3 and IEC/EN 55024 EMC standards.
