• Accurately measure power
storage and efficiency: In addition
to high-accuracy voltage and
current measurement capabilities,
APS power supplies offer built-in
power, peak power, amp-hour,
and watt-hour calculations. These
measurements help simplify your
power efficiency and storage
calculations.
• Additional measurement
capabilities:
• Adjustable measurement
intervals for both average and
digitized measurements
• External logging capability,
which simplifies data logging
in ATE software
• Pre-, post-, and level triggering
for pinpointing exactly where
and when to measure
• Accurately capture dynamic cur-
rent profiles: APS has two current
measurement ranges that allow it
to measure micro-amps to amps.
The APS uses seamless ranging
technology to transition from one
measurement range to the other
without discontinuities in the out-
put power or in measurement data.

Notes:
1
Current sinking up to 100% of rated current requires one power dissipator for 1 kW models, and two power
dissipators for 2 kW models. 2 kW models with one power dissipator can sink 50% of their rated current.
