Artesyn Embedded Technologies, formerly Emerson Network Power's Embedded Computing & Power business, introduced the first Titanium efficiency bulk front-end power supply in its standard product range: the DS3000TE-3.
This new 3,000W power supply uses proprietary Artesyn power switching technology and high density component packaging techniques to provide servers, networking, telecom, and other redundant power applications with the highest efficiency solution. The DS3000TE-3 fully uses the current capacity of 208V to 264V AC distribution lines, allowing systems to draw the maximum amount of power at the least amount of losses.
It has been certified by 80 PLUS to greater than 96 per cent efficiency at 50 per cent load, defined as Titanium efficiency. A Platinum efficiency version, the DS3000PE-3, is also available in Artesyn's DS3000 series to provide customers with an alternative option for more cost-sensitive systems, while still offering a high power density of 24W/in3.
Artesyn DS3000 series power supplies generate a main payload output of 12V DC for feeding downstream DC-DC converters in systems using distributed power architectures, together with a 12V DC standby output rated at 4.5A for power management circuitry. The main DC output of the DS3000 series can deliver up to 250A, and stays within regulation down to zero load. Measuring just 4.15in x 2.78in x 11in (105.5mm x 61.5mm x 282.6mm), six units can fit in a standard 19in rack for a total of 16.2kW. Active current sharing helps maximise cost-effectiveness by eliminating the need for additional components when paralleling multiple power supplies for very high current applications.
Artesyn DS3000 series power supplies are digital and compatible with Artesyn's universal PMBus graphical user interface, allowing control via an integral I2C interface using the industry-standard PMBus communications protocol. Extensive performance monitoring facilities enable system integrators to implement sophisticated power management schemes—in addition to input and output voltage and current, real and reactive input power and power supply temperature values can be retrieved via the I2C bus interface.
