a variety of testing to introduce the sweep of voltage, frequencies, transients, and DC bias; and 14 built-in custom waveforms
to simulate abnormal testing conditions.
"We've also seen a shift towards more automated transient
and waveform synthesis testing," Piotrowski said. "With automation, giving flexibility to customize programming is key.
We've moved toward not only offering out-of-the-box software
(PowerTRAC), but also offering LabVIEW drivers and implementing SCPI protocol on the APT 8500 Series."
Piotrowski said the company "...implemented a unique modular switching-supply approach..." for its APT 8500 Series. "This
allows us to not only offer the advanced features we've discussed,
but also reduce the size and weight of the sources." He added
that the sources can serve in MIL/aerospace, LED, appliance,
motor, and medical-test applications and help perform EMC
test in accordance with IEC 61000.

Versatile Power has recently released
its new 1,500-W RACK programmable
power supply, according to Mark C.
Brown, manager of sales and marketing. "All Versatile Power supplies come
standard with LXI," he said, adding that
other standard features include analog, USB, and Ethernet inputs
and wireless remote sense.
Brown continued, "Versatile Power's BENCH and RACK Series
both offer extended range,1 which allows the end user to use
one power supply to cover a larger range of voltages and currents, thus reducing the number of units that are need to be
purchased for their applications or testing and can be used on
cross platform projects that our customers are working on currently or that are in the pipeline."
He also noted that BENCH and RACK Series products use
the 1U footprint while delivering high power, adding that the
products' digital design contributes to the small formfactor. He
also commented, "ATE, burn-in, and avionics are a few of the
markets Versatile Power serves."

New 5,000-W and 3-kVA products
"Despite unprecedented challenges faced this year, B&K
Precision released the new MR Series programmable DC power
supplies and 9830B Series programmable AC sources," said Aaron
Fernando, product marketing engineer. Both products target
system integrators.
"The MR Series features an LXI-compliant LAN interface
and delivers 5,000 W in a compact 2U form factor," he said.
"Furthermore, these power supplies are B&K Precision's first
cTUVus approved instruments, fulfilling equivalent CSA and
UL safety standards."
Fernando described the 9830B Series as a high-performance
single-phase AC source delivering output power up to 3,000 VA
with low harmonic distortion. The frequency range is 45 to 1200
Hz. "In addition to AC, these models can output DC or AC+DC
signals," he said. Other features include a power meter with
12 measurement functions, built-in and user-defended THD
waveforms, and an amplifier mode with a 1.2-kHz bandwidth.
"The 9830B Series programmable AC sources represent our
first 3-phase-capable products, Fernando continued. "3-phase
is accomplished by using three AC sources connected to small
synchronization adapters. The adapters and connecting cables
are included in a convenient kit. The synchronized AC signals
