Overcome your power test challenges with the Advanced Power System family

With the Keysight Technologies Advanced Power System (APS) 1 kW and 2 kW system power supplies, you get a new level of power supply performance. The Advanced Power System (APS) family was designed with VersaPower architecture to help you overcome your toughest power test challenges by delivering industry-leading specifications and innovative features in an integrated solution for today’s advanced ATE power testing needs.

VersaPower architecture delivers the fastest, most accurate, integrated power system.

• Accelerate test-system throughput with industry-leading speed

• Capture your DUT’s current profile with accurate measurements

• Reduce your ATE development time and cost with highly integrated capabilities

Get lots of power in a small test-system footprint

Two power ranges deliver a large amount of power in a small test-system footprint:

• 1 kW models have a 1U full-rack footprint

• 2 kW models have a 2U full-rack footprint

• Both power ranges have built-in paralleling capability of up to 10 kW

Accelerate test throughput with industry-leading specifications

Shaving seconds or even milliseconds off a test time can lead to significant savings for high-volume manufacturers, making throughput gains a never-ending quest for test system designers. The APS is a valuable tool for increasing throughput. It provides a number of industry-leading specifications and innovative features that can help you achieve significant throughput gains in your testing. Some examples:

• Industry-leading command processing time (<2 ms)

• Fast up and down programming speeds (up to 500 μs)

• Adjustable measurement times for optimum measurements in minimum time

• Seamless ranging capability for fast current measurements without sacrificing accuracy

• Output lists that allow you to step through timed or triggered voltage or current levels that can also generate triggers for tightly synchronized measurement

Continuously source and sink current for power storage test applications

When operated as standalone units, APS power supplies can continuously sink up to 10% of their rated output current for an indefinite time. With the addition of APS N7909A power dissipater units, APS power supplies can continuously sink up to 100% of their rated output current. This means you can sink the power supply’s full-rated output power for an indefinite time. Note that the two-quadrant sourcing and sinking capability of the DC power supply allows for continuous transitions between sourcing and sinking current without changing the power supply’s output characteristics or introducing any disruptive behavior. These capabilities make the APS an ideal solution for continuous source and sink testing needs in power storage applications. For more information on the APS N7909A, see page 12.

APS N7909A power dissipater unit

The optional N7909A power dissipater unit adds current sinking or two-quadrant operation to any N6900 or N7900 power supply. Each N7909A provides up to 1 kW of current sinking capability to an APS power supply, so you will need two N7909As to achieve the full two-quadrant operation of a 2 kW APS supply. You can use a single N7909A with a 2 kW APS power supply to achieve 50% current sinking capability. The N7909A form factor is 1U with full rack width. N7909A connects to an APS power supply via a twowire power connection and a communication connection to provide continuous two-quadrant operation. The connections are located on the rear panel of both the N7909A and the supply, as shown in Figure 7.
