The DS1200 series is Advanced Energy's highest power, highest density bulk front end AC-DC power supply in the industry standard 1U x 2U form factor. It accepts a wide range 90 to 264 VAC input and provides a main 12 V output plus a 3.3 V or optional 5.5 V standby output. Rated at 1100 W, it has a high half-load efficiency of 91%. Housed in an industry standard 1U x 2U rack-mounting package, the power supply is designed for servers and similar space-constrained applications. This series comes in two airflow versions – dc-connector to ac-connector and vice versa.
The main 12 V output can deliver up to 100 A and stays within regulation down to zero load, making it perfect for feeding downstream DC-DC converters in systems that use distributed power architectures (DPA). Standard features include active current sharing, internal ORing FETs and an EEPROM for storing service data to facilitate efficient field replacement. The DS1200 power supply is hot pluggable and ideal for fault tolerant and N+1 redundant applications.
This digitally-controlled power supply is PMBus® compliant. A built-in I2C serial interface allows set-up, monitoring and control to be performed using Advanced Energy's universal PMBus graphical user interface.
