Behlke® quality products are worldwide protected by trademark and
patent rights. Nevertheless from time to time we find dubious dealers in the
internet, which offer primitive plagiarisms of our products, of course
without the reliability and the performance of the original. They
often look exactly
like Behlke® products, but they are of
lousy quality and are in no way comparable with the originals. Those plagiarisms are of poor performance at best, but often they are
very dangerous too.
To ensure, that you get the original Behlke® product and that you
receive always a true value for your money, we suggest you to check the
Should you find a new and
unknown “competitive” product on the market and if you are not sure about its
quality, then please check these points:
- Has the
“competitor” the necessary production facilities to manufacture
ambitious industrial products at all? Helpful is often a simple view on
the competitors facility address by means of Google Maps, Google Street
View or Microsoft Bing. Be careful, if there is just a family home, a
garage or something similar.
a businessman in the internet, who
has used our
including a product
to sell his
"own" products. He even claims to be the inventor of those high
voltage switches! When we searched his industrial production facility in
we found this.
The plagiarism has been
by our engeneers and here is a brief laboratory report about the
(please click here).
“competitor” the expertise for MIL or HIREL qualified microelectronics
production processes including dry component storage, full component
screening, component tracking, visual inspection etc.?
“competitor” run a well documented and sufficient quality system? Is it
executed by an independent and certified quality inspector? Is there a real
serial production with quality improvement statistics?
long-term reliability of the products proven by continuous tests? Does
the “competitor” run extensive climatic and temperature cycling tests by
using sufficient test equipment? Is there any documented burn-in
solid-state products manufactured in a clean and ESD-save environment?
“competitor” use professional electronic manufacturing technologies and
machineries, such as part component desiccation, plasma treatment,
automated SMD placement, machined vacuum potting etc.?
How long is
the “competitor” on the market? Is there any significant
competence in high-voltage related materials and high-voltage circuit
design? Does he offer OEM products for medical,
military and other safety relevant applications? Are there references?
- Has the
“competitor” the expertise to manufacture reliable solid-state switches
in any configuration and in any semiconductor technology for voltages up
to 150 kV and above? Is he able to design reliable solid-state switches
with di/dt’s of 20 kA/us and above?
- Has the
“competitor” the expertise to built compact solid-state switches
with 200 kV isolation voltage?
“competitor” the expertise to manufacture high-voltage solid-state
switches for continuous high power dissipation, e.g. in the Kilowatt
range? Are all kinds of cooling methods available, such as cooling fins,
cooling flanges, water cooling and direct liquid cooling? Has the
competitor the expertise to make heat sinks with sophisticated materials
such as copper compound, graphite and ceramics?
“competitive” switching module equipped with an “intelligent” control
circuit? Does it provide advanced EMC filtering functions, control
signal conditioning, frequency monitoring, temperature protection,
auxiliary voltage monitoring, over voltage protection, fault flag
signal, inhibit function etc.?
- Is the
“competitive” switching module working over the whole temperature range
without any restriction? Has the control signal any influence on the
switching behavior? Is it possible to turn-off higher currents also at
shorter on-times safely and without damaging the semiconductor
Or becomes the switch unstable at short control pulses?
- Are all
the technical data of the “competitive” product comparable to Behlke®
products or is there just a similarity in a few specifications? Does the
competitor specify the exact test conditions for the purpose of
“competitor” grants at least two years warranty for his products?
In case of any doubt, please do not hesitate and contact us under firstname.lastname@example.org
Or simply buy the original directly
from Behlke®, the
inventor of fast high-voltage solid-state switches.
