LCOS current monitoring system - hard as steel In case of expensive or dangerous system Full control when it is really failures, a low-voltage network (Isolé Terre) important! provides the best solution for load monitoring. This could be very important in the steel, shipbuilding and mining industries, or in hospitals, airports, computer centers or control centers. The ground in these systems is separated galvanically from the active conductors which means that the power supply is not switched off immediRead the entire article about the harsh ately in the event of an error.

Power Supplies · Basics 2. Safety A power supply has a decisive influence on the availability and operational reliability of electrical systems. The safety of people and equipment is always the priority. Accordingly, power supplies must comply with unified regulations and standards. Consequently, the selection of the right power supply should be just as critically and carefully undertaken as that of the other system components. 1. General structure Regardless of the technology employed, power supplies are devices with an input side and an isolated output side. Galvanic isolation generally...

2.5 SELV SELV according to IEC/EN 60950 is a safety extra low voltage which thanks to its low level and insulation offers better protection against electric shock than higher-tension circuits. Power supplies generating SELV, for example, must be designed to prevent shorting between the primary and secondary windings and their connections. The windings can only be overlaid if double or reinforced insulation is placed between them. This isolation is termed galvanic isolation. Grounding of the secondary side is not required but permitted. The peak value must not exceed 42.4 V in case of AC...

Power Supplies · Basics up to a degree where safe operation is no longer guaranteed. There are a number of techniques for protecting the power supply against destruction due to overheating. • The maximum output power is reduced, allowing the power supply to cool down. U/I characteristic Lütze power supplies with a U/I characteristic perform current limiting to typically 1.2 times the nominal current at constant output voltage. This current is still available in case of an overload or a short circuit. The voltage is slowly lowered, while the output current may rise further (triangular...

Parallel selectivity Based on the self-protection, the output voltage is switched off or reduced in the event of a fault. If multiple loads are carried on one power supply, a voltage drop will occur throughout the entire application. To prevent this, protective devices are installed in the individual lines to the consumers. If a fault occurs, the protective device concerned must trip fast enough so as to disconnect the faulty consumer reliably from the rest of the system and such that the other consumers remain available. 8.4 Connection cross-sections The line cross-sections are selected...

Reliable protection of DC 24V circuits Intelligent safeguarding of selectivity Primary switching controllers and automatic power units nowadays form the basis of the DC 24V supply level. Due to the operating behaviour of those devices, the specified selective protection of individual circuits, especially in case of overcurrent, is virtually unfeasible. A complete system shutdown is inevitable. Operating behaviour of primary switching controllers Switched-mode power supplies and their components are rated for a specific nominal value and run hot under higher load. To protect against...

LUTZE Ethernet Connectivity - Solutions from a single source The requirements placed on efficient manufacturing systems are becoming more and more complex. Increased networking between production and management means that more and more automation systems are requiring the use of PC-based controllers and Ethernet communication networks. Ethernet is the name of a widely used, standardised communication infrastructure with various communication media. Together with higher-level communication software, Ethernet is today the basis for a large number of industrial local networks. In contrast to...

Ethernet Connectivity · Basics Cables - A lot depends on them The classical Ethernet began with the coaxial cable. Today, new installations use only symmetric cables, so-called balanced cables, or fibre-optic cables. CAT 2 - Class B CAT 2 cables are suitable for maximum frequencies up to 1 or 1.5 MHz; they are used, for example, for cabling in buildings with an ISDN primary multiplex connection. Copper cables Various types of copper cable are used. The term "symmetric cable" does not refer to the structure of the cable, but rather exclusively to its electrical characteristics and the signal...
