POWER SUPPLY SOLUTIONS
Digitally Controlled, Modular Power Supplies 
Modular design and onboard processing delivers programmable, application-specific AC/DC solutions

Astec Power has introduced a new generation of digitally controlled, configurable, medium power AC/DC switching power supplies that can provide application-specific solutions with more functionality than a conventional fixed output supply - without cost or time penalties.

Representing the industry’s first digitally controlled AC/DC switching power supplies, Astec’s iMP series combines modular design with an onboard microprocessor for programmability and smart communications.



In addition to delivering 50% higher power density than previous generation products, the new switching power supplies use integrated intelligent I²C capabilities to provide smart communication and programmable control features that enable designers to precisely fine tune power for their needs throughout the development process.

The easy-to-use microprocessor interface and built-in functionality allows designers to make adjustments to a host of parameters and program key features on each output, including voltage, output enable/sequencing, DC OK thresholds, output current limit and overtemperature threshold.

The modular design gives designers the ability to tailor solutions within a selection of three customisable cases in power ratings from 750W to 1500W, accepting input voltages from 85VAC to 264VAC or 120VDC to 350VDC. Modules can be selected as single-, dual- or triple- outputs in power ratings from 36W to 750W. Cases can accommodate up to seven individual modules allowing from one to 21 outputs with output options ranging from 2VDC to 60VDC.
