The Artesyn Embedded Power DS850-3-006 is an 850-watt AC-DC converter designed for rack-mount and embedded systems requiring a reliable +12V main output. It delivers up to 70A on the main +12V rail and includes a +3.3 Vsb standby output (6A) for auxiliary power.
The converter accepts a universal AC input from 90 to 264 VAC and also supports a -40 to -75 VDC input, making it suitable for both AC and redundant -48V telecom power architectures. Efficiency is rated at 82%.
Key protection features include overcurrent protection (77-105A), overvoltage protection (13.2-14.4V), and undervoltage lockout (9-10.8V). The unit includes hot-swappable capability, an I2C interface for monitoring, load sharing, remote sense, and PFC. Turn-on delay is 2 seconds max, and the +12V rise time is 10-300 ms monotonic.
Cooling is not specified but the operating temperature range is -10 to +50°C. The DS850-3-006 meets FCC Subpart J and EN55022 Class B for conducted and radiated EMI.
