1100W Front Ends for Wider Range of AC and DC Inputs

Artesyn Embedded Technologies today announced the extension of its 1100W DS1100 bulk front end power supply family with two new series that accept a wide range of 90- to 264-Vac and -40- to -72-Vdc inputs. The DS1100SL series is designed for system designers looking to minimize space requirements in network switches, routers, enterprise servers and similar space-constrained application.

The new DS1100SLPE-3 ac-dc and DS1100TDC dc-dc power supplies are housed in industry standard 1U x 2.1-inch rack-mounting packages, with the same output connector. This makes it suited for data center applications where both ac and dc power are needed.

The DS1100SLPE series bulk front end provides a main 12Vdc output plus a 3.3Vdc standby output. It is an 80 Plus Platinum supply with a high peak efficiency of 94 percent and the main 12V output can deliver up to 90A. The DS1100TDC series is a dc-in version of the bulk front end and provides a main 12Vdc output that can deliver up to 91.7A, plus a 3.3Vdc standby output.

Both new power supply series’ stay within regulation down to zero load, making them suited for feeding downstream dc-dc converters in systems that use distributed power architectures (DPA). Active current sharing enables multiple supplies to be paralleled for very high current applications without need of additional components. The power supplies are hot pluggable and ideal for fault tolerant, N+1 and N+N redundant applications. They are available in two airflow versions – dc-connector to ac-connector and vice versa.

These digitally-controlled power supplies are PMBusâ„¢ compliant. A built-in I2C serial interface in each solution allows set-up, monitoring and control to be performed using Artesyn's universal PMBus graphical user interface.
