TDK-Lambda's single-output ZWS-BAF
series are 100 and150W supplies accept a wide ac input
range, have a low profile of 1.3 to 1.45 inches and compact footprints of 2.44
x 6.1 inch or 3 x 6.3 inch, making them an option for
applications in light industrial, LED signage, test & measurement, gaming,
point-of-sale and IT equipment.
These new open-frame supplies feature a universal 85-264V
ac, 47-63Hz input, with PFC, enabling them to be used anywhere in the world and can operate from a 120-370V dc
input. The ZWS-BAF
is designed to withstand 3kV ac, input-to-output. The series are available with
an output voltage of 3.3, 5, 12, 15, 24V or 48V dc, all of which have a +/-10
percent adjustment range.
With convection cooling (no fans required) these
supplies provide up to 150W of output power.
The operating temperature range is from -10 to +70C with derating above
50C to 50 percent load. The output is floating so it can be used as either a
positive or negative polarity.
Optional remote On/Off connections
are provided to allow for remote control of the supply. The operating power-saving
efficiency is up to 90 percent. Other standard features include overvoltage and
overcurrent protections. The input and output connections mate with standard JST connectors.
series is an extension of the ZWS series.
The ZWS-BAF series feature
global ITE and general purpose safety agency certifications per UL/CSA/EN60950-1,
EN50178 (OV II), are CE Marked, meet the conducted and radiated EMI
requirements of EN55011/EN55022-B, VCCI-B and FCC Class B.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
Using Siemens NX software, a team of engineering students from the University of Michigan built an electric vehicle and raced in the 2013 Bridgestone World Solar Challenge. One of those students blogged for Design News throughout the race.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
