NGM200 power-supply series
Being part of the same power supply family, the R&S NGL200 and the new R&S NGM200
Series offer the same performance and specifications to supply stable outputs with a minimum
of residual ripple and noise. Devices that switch from a few microamps in sleep mode to
several amps in active mode benefit from the fast load recovery time of less than 30 µs. The
2-quadrant architecture provides both source and sink functions, to simulate the charging
and discharging of batteries as well as to operate as an electronic load. In addition, the R&S
NGM200 Series includes four new features: the FastLog function that captures spikes even in
the µs range, additional measurement ranges that increase the read-back accuracy in the lower
ranges, a battery-simulation option that supports the modelling of batteries to simulate real life
conditions, and a built-in digital voltmeter that measures voltage values at any point in circuits
of the device under test.

3-phase 4,080W 24-V industrial power supply
The TDK-Lambda brand TPS4000-24 power supply extends the existing 3,000-W
rated TPS series. Delivering up to 4,080-W output power (24 V at 170 A) in a 2U-high
package, the TPS Series operates from a delta or wye 350- to 528-VAC 3-phase input.
This industrial power supply is suitable for use in many applications including test and
measurement equipment, semiconductor fabrication, additive manufacturing, printers,
lasers, and RF power amplifiers. The high voltage, 3-phase input avoids the requirement
for costly step-down transformers and assists phase load current balancing. The
TPS4000-24 features isolated AC fail, DC good, and dropped phase signals, remote on/
off, remote sense, and a 12-V 0.3-A standby supply. TDK Corp.

TESTING FRONTIERS
Consider, if you will, an electronics industry
without test & measurement.
Of course, one cannot survive without the other. Test
engineers are indispensable team members dedicated to
the success and safety of electronics products and their
components. EE-Evaluation Engineering, a monthly magazine
dedicated solely to test & measurement, recognizes this
fact and follows the daily changing trends, products, and
developments that you can use, as a guardian of quality
and precision in an industry that is pivotal to the future.
