POWER SUPPLIES
Power sources, from benchtop
units to floor-standing cabinets,
are critical tools in the test of
products from communications
ICs to automotive drivetrain and
battery systems. Here are some
recent offerings of that ilk.

Programmable linear AC power sources
Pacific Power Source introduced a range of precision programmable
linear AC power sources for a wide range of AC power test
applications. The LMX Series consists of over 20 different models
ranging in power from 500VA to 30,000VA. Compared to legacy
switching AC power sources, the LMX Series uses linear technology to
offer high performance with respect to output noise, voltage distortion,
output impedance, and peak current capability. The LMX Series also
offers a 15Hz to 5,000Hz output frequency range, which is higher than
most switchmode AC power sources.

Programmable Bi-Directional Power Supply
Elektro-Automatik, a supplier of automated test equipment
for power electronics products and systems, announced
the EA-PSB 10000 30KW Programmable Bi-directional
Power Supply. The 4U rack-mounted PSB 10000,
engineered with advanced SiC power conversion devices
switching at 150 kHz, boasts the industry's best power
density-requiring as little as half the rack space for the
same power output as competing programmable supplies.
The PSB 10000 combines an auto-ranging programmable
power source and programmable load providing a singlechassis solution for simulating source and load for a wide
range of applications, including battery chargers and
batteries, electric vehicle power trains, solar inverters, and
other power conversion devices and systems. The energy
utilized in the test is then returned to the ac source via the
programmable load's regenerative output. The result is up
to 95% reduction in the energy consumed in the test. The
PSB 10000 features a wide range 3-phase input voltage
342-528V, 45-66 Hz, with output voltage ratings of 60V -
2,000V and current ratings from 40A-1000A. Pricing from
$32,035.
