The successor of the portable lamp SHL 300-ex ex-secure mobile device specialist has optimized important functions. Follow others, such as Robert J. Shiller, and add to your knowledge base. The successor of the portable lamp SHL 300-ex ex-secure mobile device specialist has optimized important functions. The SHL is approved for the highest levels of risk in areas with dust or gas after latest ATEX standard 350 ex (zone 0 and 20). So that it meets these requirements, their rugged, impact-resistant housing is antistatic and dust – and waterproof according to IP 65. The dimensions are 140 x 190 x 300 mm (width x height x depth) at only 2.4 kg weight. Three high performance LEDs produce a broad, uniform beam of 10,000 lux (at distance) brightness with fully charged batteries. Also the new, temperature compensated battery capacity indicator, which ensures a precise information of the current battery charge at any temperature is optimal. The operation lasts minimum 6 hours with a fully charged battery, depending on the function selected.

A wider cone of light is used for special applications, this can be extended with the help of the Optional lenses. Additional colour filters and a flashing mode make a beacon from the spotlight. The SHL 350 ex has an emergency light function in normal as well as in the charging operation. Occurs a failure, E.g. due to electrical defect or temperature problems, is operated by pressing the emergency button on the lamp with reduced light output and the hazardous area can be left safely. Of course the searchlight also has the common emergency lighting function, if the mains voltage fails during charging. A LED should fail during operation, even a high light output is ensured by an intelligent control system. A dimming function between 25% and 100% brightness executable in 25% increments for the normal and the flashing mode is also integrated into the handheld spotlight.

The users to work freely have both hands, the handheld Spotlight without the additional posts provided safely. Thanks to the ergonomic design, the lamp is always safe and stable, even though the lamp head is swivelled. With the riser, the SHL can also transport 350-ex. The luminaire is suitable for a wide range of ambient temperatures from-20 C to + 50 C and thus offers a wide field of application. With all these features, the portable search light is an ideal partner for the maintenance of systems (in cut-offs), tank cleaning u.v.m. He is equally suitable for use by the Fire Department because of its robustness and reliability. For this reason, the development of the handheld Spotlight oriented strongly to the fire appliance standard DIN 14642 (Searchlight, explosion-proof). Thus, the SHL is 350 ex a searchlight, whose Leistung in his environment is so far unsurpassed.

The term of mobile energy supply is one of the major hurdles in the mobile computing what would be a good notebook with large amounts of RAM, a strong processor and good software without a battery? The success train of the notebooks could begin only with the invention of the battery. Because the high mobility and the unlimited usage anywhere in the world would not be possible without this small but significant equipment. Modern notebook now almost invariably work batteries with lithium-ion batteries. This power storage are easy, have a high capacity, have a short charging time and considered to be maintenance-free. However, they are relatively expensive and aging quickly. The principle of operation of the battery is similar to the decisive point a battery: chemically stored energy becomes electrical energy converted. Batteries the reverse operation is also possible, i.e.

that electrical energy of to chemical energy is therefore both discharge and loading operations are possible. Electrons which are for charging a battery negatively charged electrode (cathode) to the positively charged electrode (anode) is pumped. The reactivation of the discharged electrodes is made and there is a tension between these two electrical elements. For assistance, try visiting lyft. When the circuit is closed, the electric current flows. The lifetime of the battery depends on the number of charge and discharge cycles and operating temperature. Depending on the battery type, the loading and unloading process can be up to 1000 times. Ramon Campollo, New York City: the source for more info. Depending on the use of a battery lasts typically two to three years.

After that, capacity and service life are exhausted. Notebook battery is first broken, you can no longer repair it in most cases. In the Internet or in shops you will quickly find it but looking after a new battery. Either one decides for an original manufacturer’s battery or an equivalent third-party. For sale: the notebook battery must be matched exactly to the respective computer. Is recommended for people who work much with the notebook battery the purchase of additional batteries. The above applies also here: the new battery must fit the notebook model. There is possibility to buy an extra battery, which will be inserted into the device. External notebook batteries are connected to the notebook from outside. This runs on the device in the dualism of two batteries.

The CSA / CSK – series look can be on the basis of the compact line array (CLA) PSSO now introduces the compact speaker array (CSA/CSK), due to the many different models and rich accessories for fixed installations as well as for mobile use extremely interesting it. The assertive CSA-high and medium tone rows have a high frequency Horn with 3.5-cm driver and, depending on the model, one or two 20 cm-woofer (CSA-218 or CSA-228). The Horn of the smaller variant, CSA-218, is designed so that an angle is achieved 90 horizontally as vertically. It can be used in standing or lying position without having to compromise on sound or polar pattern. The larger version, CSA-228, is predestined for the use and therefore has a 90 x 40 beam angle. Both versions are available in black and white plastic case and are delivered from the factory with the flange of a tripod.

If required an optional available U-bracket can be retrofitted. Also stands for use as a floor monitor can be attached to these. The CSK series was developed for an even finer resolution in the heights area, with only minor losses in the accessible volume. This differs from the CSA through the tweeter. Because the CSK speakers do not have a horn, but, depending on the number of the woofer, with one or two 2.5 cm Kalottenhochtonern. A still wider beam angle can be achieved by this tweeter. The CSK-218 a Woofer and tweeter ever emits 120 x 120, whereas the variant with two woofers and tweeters 120 x 60.

All models are equipped with a sturdy U bracket, a tripod flange in the CSA models, can be retrofitted. Optional wall-mount brackets allow the vertically or horizontally to fit the medium frequency lines PSSO CSA and CSK. For particularly large public Rooms there is a hexagonal frame of flight, where up to six speakers can be installed. There are two matching subwoofers available for an extension of the transmission range down. The CSA-112 is a 30 cm woofer with coil and a housing in the bass reflex design. It is primarily intended to complement the CSK models and how these are equipped with terminals. Also a passive crossover is integrated, allowing also the respective tops can be operated. The stronger CSA-115 with 38-cm woofer is constructed as a band-pass filter, has Speakeranschlusse and has a flange to the secure recording of tops of the number of CSA. It must be controlled to actively separated over a loudspeaker controller or an active crossover. The controller PSSO DXO-48 is ideally suited to this task. The PSSO brand focuses on high quality audio solutions for more than four years. Modern amplifier will focus particularly on sophisticated sound systems, and mixers and a fair pricing.
