High-frequency, low-energy interference can be smoothed and eliminated using interference filters. Meanwhile lightning and surge protective devices provide protection against transient and high-energy voltage peaks.
The protective circuit principle:
An "effective protective circuit" helps to implement seamless surge protection.
And this is how it works:
Draw an imaginary circle around the object you want to protect.
Surge protective devices must be installed at all points where cables intersect this circle.
The area within the protective circuit is therefore protected in such a way that conducted surge voltages are prevented.
Consider the following areas during planning:
• Power supply
• Measurement and control technology
• Data processing, telecommunications
• Transceiver devices
It is generally recognized that residential buildings place different requirements on lightning and surge protection than industrial installations. Our complete concept for surge protection offers user-friendly, ready-to-install solutions for all applications.
Safe Energy Control Technology: Safe Energy Control, SEC for short, is synonymous with exceptional durability and the highest performance in the field of lightning current and surge protection. The revolutionary spark gap technology safely prevents any line follow current. This reduces the stress on the entire installation to a minimum. This at the same time means extraordinary durability for the surge protective devices. The protective devices operate inconspicuously and sparingly for the entire system. Solutions without backup fuse are available for all applications.
Protection for every application: Surge voltages are potential interference factors. Without effective protection, you can expect high costs for repairing or replacing the equipment affected.
The multi-stage concept from Phoenix Contact provides effective protection for your systems and devices.
Type 1 protection stage: powerful lightning arrester.
Type 2 protection stage: surge protection that is essential for any power supply unit
Type 3 protection stage: surge protection for sensitive devices
Combinations of lightning and surge arresters are also used.
Protection for US network types: Surge protection for US installation requirements according to UL 1449 3rd Edition and NEMA
Benefits
• Can be used in all standard power supply units, thanks to powerful components.
• Seamless protection across all protection stages, thanks to coordinated arrester.
• Space-saving and inexpensive installation, thanks to slim design
When a number of signal cables are installed in parallel, voltage peaks can have a disastrous effect. Our surge protective devices for measurement and control technology consist of powerful components with a low protection level which respond quickly. This means that your signals and measured values remain available and undistorted.
Phoenix Contact offers innovative surge protection components for all requirements in measurement and control technology with below features:
• Plug in.
• Status display
• Remote Signalling
• Latching
• IS Version
• Push in Connection Technology
• Screw Connection Technology
Typical fields of application for surge protective devices for measurement and control technology are:
• Process technology
• Water and waste water technology
• Power engineering
• Traffic engineering and building automation
Use our devices to protect all common signals: from 2-wire through to 6-wire technology, such as temperature measurement or current loops.
Choose between one-piece or multi-part protective devices for the DIN rail and screw-in devices.
Benefits
• More space in the control cabinet – thanks to compact design
• Protection for all common signals, thanks to the complete product portfolio.
• Service that can be planned thanks to self-monitoring protective devices (PLUGTRAB PT-IQ)
• Worldwide use in potentially explosive areas, thanks to ATEX and IEC Ex approvals
• Versatile use: designs and connection methods adapted to the application
• Easy testing thanks to plug-in design of arresters (PLUGTRAB PT)
Have you installed a photovoltaic system on your building? Perhaps you also operate a wind farm or solar power plant? Then it is essential that you protect your investments and yield against damage caused by lightning and surge voltages.
Protect your investment:
Renewable energy sources are becoming increasingly important. Wind power and photovoltaic have seen a significant increase in installations.
However, the systems are at particular risk from lightning currents and surge voltages. This is because most are situated in exposed locations or they are at particular risk of lightning strike due to their surface area.
Take preventive action: surge protection significantly increases the availability of your systems.
Protection for photovoltaic systems:
PV systems require special protective circuits. Depending on the system configuration and grounding conditions, we provide suitable arresters that can safely handle these high DC voltages.
Pre-assembled set solutions simplify the installation of surge protection in your PV system.
In addition, tracking and monitoring systems must also be protected against interference and data loss. Use appropriate arresters to protect the data and control cables.
