D1U-H-2800-52 : High power density and high efficiency front-end power supply delivers 2800W output for mission critical distributed power architectures EN | FR | DE | CN | JP | DN The D1U-H-2800-52-Hx from Murata Power Solutions is a 2800W (220VAC), power-factor-corrected AC/DC front-end power supply that offers industry-leading power density of 27.7W per cubic inch. With 91.6% efficiency at full load (measured after the output Oring diodes and with fans running at full speed), and 92.0% efficiency at 2kW load, the D1U-H-2800-52-Hx also has amongst the best efficiency figures in the industry. The RoHS compliant design is packaged in a 1U low-profile housing and has a main output of -52V and a standby output of +12V. The new power supply is N+1 redundancy capable and suitable for hot-docking. It is ideal for use in mission critical 48V distributed power architecture systems in data communications equipment. If required, three units can be packaged into an optional 19in., 1U power shelf to provide up to 8.4kW of power. Design features include over-current and over-temperature protection with auto-recovery, over-voltage protection, and active current sharing or droop current sharing. Status information is provided via front panel LED indicators, logic signals and an I2C bus management interface. The D1U-H-2800-52-Hx has a highly efficient electrical and thermal design that incorporates internal cooling fans. The series comprises two models - one providing front-to-back airflow and the other back-to-front flow. Overall dimensions of the D1U-H-2800-52-Hx 1U enclosure are 11.5in. x 5.5in. x 1.6in. Operating temperature range is 0ºC to +50ºC. Ref. MPS248A
