CARLSBAD, Calif. - Emerson Network Powe has announced the introduction of a new generation of switching power supplies featuring sophisticated digital management capabilities from Astec Power ( Along with digital control, the new iMP Series offers a range of hardware modules that will give designers the ability to tailor solutions precisely to their individual needs with single, dual, and triple output modules in power ratings from 600W to 1500W. Modules can be configured in a selection of four customizable MP cases accepting input voltages from 85VAC to 264VAC or 120VDC to 350VDC. Cases can accommodate up to seven individual modules with a choice of outputs ranging from 2VDC to 60VDC.

“In addition to having 50 percent higher power density than previous generation products, this new breed of switching power supplies uses integrated digital capabilities to provide smart communication and programmable control features that will enable designers to precisely fine tune power for their needs throughout the development process,” explained Astec product marketing director Chris Jones. “The easy-to-use microprocessor interface allows designers to make adjustments to a host of parameters including: voltage, current, fan speed, sequencing, power factor correction, inrush and more. In spite of the advanced feature set, designers should find that this new digital generation of intelligent switching power supplies be price competitive with existing technology,” according to Jones.

Using the iMP Series intelligent I2C control, designers can program key features on each output, including:

* Output Voltage
* Output Enable/Sequencing
* Module Inhibit/Enable Polarity
* DC OK Thresholds
* Output Current Limit Set-Point and Type
* Overtemperature Threshold

With the increasingly popular I2C communication protocol, these systems will also be able to capture configuration and use information as well as parametric data for each output.

Backed by a two-year warranty, the iMP Series products meet worldwide safety and performance standards including listings from UL and CE as well as full medical compliance with EN60601. Samples will be available in the fourth quarter of 2005 with prices starting at $320 for a single-output 600W configuration. Because the modular design enables more than 200 million combinations, pricing will vary based on configuration.
