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.
A Tokyo company, Miraisens Inc., has unveiled a device that allows users to move virtual 3D objects around and "feel" them via a vibration sensor. The device has many applications within the gaming, medical, and 3D-printing industries.
In the last few years, use of CFD in building design has increased manifolds. Computational
fluid dynamics is effective in analyzing the flow and thermal properties of air within spaces. It can be used in buildings to find the best measures for comfortable temperature at low energy use.
