The DS1200DC series bulk front end power supplies is the DC-input version of its DS1200 AC-input counterpart. Mechanically identical to the AC-input version, this product allows system operation from a Telco style 48 VDC input. Rated at 1200 W, the power supply provides a main 12 V output and a 3.3 V or optional 5.5 V standby output. Active current sharing allows this power supply to be paralleled with the AC-input version, for use in battery back-up systems where both AC and DC input capabilities are required.
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 internal ORing FETs and an EEPROM for storing service data to facilitate efficient field replacement. The DS1200DC 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 communication interface allows set-up, monitoring and control to be performed using Advanced Energy's universal PMBus graphical user interface.
