DS500SDC Series

The DS500SDC-3 series of 500 W bulk front-end DC-DC power supply accepts an input of -36 to -72 VDC and provides a main 12 V output plus a 12 V standby output. Housed in a 1U high rack-mounting enclosure with a short form factor that frees up system space, the DS500SDC-3 has a power density of 10.9 W per cubic inch. This series comes in two airflow versions – dc-connector to ac-connector and vice versa. The series is also in the same form factor and has the same output configuration as the DS500SPE-3. With a main 12 V output delivering up to 41.67 A and staying regulated down to zero load, they're perfect for feeding downstream DC-DC converters in distributed power architectures (DPA). This digitally-controlled power supply is PMBus^® compliant with a built-in I2C serial interface that allows set-up, monitoring and control via PMBus GUI.
