The Artesyn Embedded Power DS450DC-3 is a distributed power bulk front-end DC DC converter rated at 450 watts. It provides a main +12 VDC output and a +3.3 VDC standby output for powering auxiliary circuitry. The unit accepts a DC input range of 36 to 75 VDC, making it suitable for Telco-style 48 VDC input applications.
Key electrical specifications include an efficiency of up to 87% and an inrush current of 21A maximum. The main output voltage is 12V with regulation of +5%/-5%, and the standby output is 3.3V with similar regulation. Overvoltage and undervoltage protection are included for both outputs.
Designed for rack mounting, this converter features a 1U x 2U form factor with dimensions of 305.6mm x 78.0mm x 40.0mm. The operating temperature range is -10°C to 50°C. It meets conducted and radiated EMI standards, including FCC Subpart J EN55032 Class A.
Additional features include active current sharing, internal ORing FETs, and an I2C communication interface for FRU data. Status indicators include amber for fan fail and green for power good.
