DDP400 Series

The Endeo DDP400 series of IT rated AC-DC power supplies feature a compact form factor and a high conversion efficiency.

The series provides a steady 400 W of regulated DC power through the full 90 to 264 VAC input voltage range.

Based on an open frame, 3.00” x 6.50” x 1.46” form factor, the series is available in five different low-profile packages to enable designers to integrate into 1U applications.

By converting energy at 94% typical efficiency, the DDP400 series generate less heat facilitating thermal management in space constrained systems and offering high reliability.

The DDP400 series is available in five standard output voltages – 12, 24, 28, 36 or 48 VDC – offer an auxiliary 12 VDC and 5 VDC stand-by outputs. Available control signals include Power Good (P_OK), Remote On/Off (PS_ON) and remote sense compensation on the (+) load line.

Boxed and vented open frame models can deliver full output power up to 50 °C, can operate up to 70 °C with de-rating and are capable of start up from -30 °C. A built-in speed controlled fan, to ensure the required airflow while maintaining minimal operational noise, which ultimately enhances the power supply service life time.

The DDP400 range complies with the IEC/EN/UL/CSA 60950-1 and 62368-1 safety standards for Audio Video and IT equipment. It also complies with the Class B limits of the standards EN55011, EN55032 and FCC for conducted and radiated emissions, IEC/EN 61000-3 Class C for harmonic content and EN 55024 for EMC immunity.
