Power supplies for ATE applications

Two high-power system power-supply families have been introduced by Agilent Technologies.The Advanced Power System (APS) family offers 1- and 2-kW power supplies for demanding ATE applications; and the N8900 Series provides programmable, 5-, 10- and 15-kW power supplies with autoranging outputs for basic ATE applications.

According to the company, the APS power supplies with VersaPower architecture offer industry-leading specifications for fast operation, advanced measurements to accurately capture power profiles and integrated features to reduce automated test system development time and support costs. The 1- and 2-kW models, expandable to 10 kW, are available in two performance classes to help test-system engineers meet their power testing needs. The APS N6900 Series DC power supplies are designed for ATE applications where high-performance is critical. The APS N7900 Series dynamic DC power supplies are designed for ATE applications where high-speed dynamic sourcing and measurement is needed.

Agilent APS power supplies help engineers overcome a variety of difficult test challenges related to power, including protecting high-value DUTs against power-related damage, maintaining output integrity under dynamic load conditions and characterizing dynamic current profiles.

The N8900 Series extends Agilent’s basic power supplies into a much higher power range at a competitive price. Engineers will be able to operate multiple units in parallel to achieve power greater than 100 kW. These new power supplies are designed to meet the testing needs of high-power applications such as electric and hybrid-electric vehicles, wind and photo-voltaic inverters, and high-voltage lithium battery packs.

The models also offer autoranging output capability. Autoranging provides test engineers more flexibility than is possible with traditional or rectangular output power supplies. Supplies with autoranging outputs can produce many more voltage and current combinations at maximum output than a rectangular output power supply, which generates just one.

“We are excited to be able to meet the needs of our customers who require high power,” said Kari Fauber, general manager of Agilent’s Power and Energy Division.  “With our entry into the high-power arena, engineers will be able to get the clean, dependable power and flexibility they count on from Agilent power supplies—but at much higher power levels.”
