Applications
Advanced circuit protection devices for overvoltage
and overcurrent transient events.
Only One Name Means ProTek’Tion™
Today’s industrial applications are as diverse as ever.
They include point of sale (PoS) systems that have card
readers, modems and serial ports. They also include residential and commercial energy meters and smart meters;
industrial displays; appliances; general control systems;
instrumentation; photovoltaic systems; LED lighting and
many more. Industrial system failures in the field due
to improper circuit protection can be costly exercises in
terms of time and money. In addition, system downtime
can often result in damage to a company’s image or
quality reputation – both that of the user and the system
provider. Any of these industrial applications are at risk to
external threats that can include electrostatic discharges
(ESD), electrical fast transients (EFT), surges, lightning or
improper wiring.
“No matter
the industrial
application, ProTek
Devices provides
a comprehensive
family of overvoltage
and overcurrent
protection devices.”
Communications systems are at the heart of many
industrial applications, such as the use of RS-485, CAN
Bus, LIN Bus, USB2.0, ProfiNet or ProfiBus. To provide
circuit protection, traditionally, a high capacitor was used
to ensure overvoltage protection. However, due to the
high speed requirements in today’s communication ports,
the capacitance per line must be significantly reduced. If
not, transmission speed will be substantially negatively
impacted. And, capacitance reduction must be done while
still providing enough overvoltage protection against electrical threats. The capacitance of the protection device
becomes a particular issue for data lines where higher
baud rates are being designed. Here, what’s required are
circuit protection components where the load capacitance
creates a first order filter to slow the rise and falling
edge.
amplitudes under fast transients. While this traditional
solution often provides adequate protection, it does use
passive components that can strain other components.
Thus, energy can then be diverted into the system power
rail, causing electrical damage into other areas of the
system. For this reason, overvoltage protection solutions
with a fast response time that divert or shunt the energy
to ground should be considered.
In addition, it is important that industrial application
designers understand that their solutions are likely to be
exposed to external ESD, EFT, surges, lightning or improper wiring during installation. This includes ESD levels
per IEC 61000-4-2 and EFT levels per IEC 61000-6-4.
Critical systems and integrated circuits (IC) will be exposed to such elements and designers should remember
that devices may not be resettable and may be damaged
beyond repair.
For surge protection per IEC 61000-4-5, it is critical for
the design engineer to understand what installation classification is required for a system. They include:
•
•
•
•
•
•
Class 0: Well-protected electrical environment, often
within a special room.
Class 1: Partly protected environment.
Class 2: Electrical environment where the cables are
well separated, even at short runs.
Class 3: Electrical environment where cables run in
parallel.
Class 4: Electrical environment where the interconnections are running as outdoor cables along with
power cables and cables used for both electronic and
electric circuits.
Class 5: Electrical environment for electronic equipment connected to telecommunication cables and
overhead power lines in a non-densely populated
area.
Once the classification is known, the level of protection
required can be determined using the IEC 61000-4-5 test
levels, as shown in table 1.
No matter the industrial application, ProTek Devices provides a comprehensive family of overvoltage and overcurrent protection devices. They are designed to seamlessly
integrate within the various electronics design requirements for today’s modern industrial electronics system.
They are also designed for quality and cost-effectiveness.
They also not only help meet all relevant standards, they
provide real-world scenario circuit protection for mission
critical industrial systems.
Power supplies are also obviously critical to industrial
systems and they can be easily susceptible to various
electrical threats. But, power supplies are generally immune to ESD conditions. This is due to the use of passive
components such as capacitors and inductors that are
inherently robust. Ferrite beads are commonly used in
power supplies to add inductance that limits the impulse
