UPS IMPULSE series SLIM 5004200 VA is a series of highly efficient, reliable and affordable UPS lineinteractive topology with sinusoidal output signal. Thanks to the builtin AVR voltage stabilizer, all models of the SLIM series maintain the output voltage within the normal range at undervoltage or overvoltage of the mains, optimally using the battery resource. This allows not only to provide guaranteed stable backup power in case of voltage loss in the incoming network, but also to protect critical equipment from damage that may result from voltage surges. Following the high requirements of fire safety, the enclosures of the IMPULSE UPS of the SLIM series are made of impactresistant ABS plastic with fireresistant properties. This inherently ensures the shock resistance and fire safety of the electrical protection equipment.

Zinc(II) chloride is used as a catalyst, as a dehydrating and condensing agent, soldering flux and metal etchant. It is also employed in preserving anatomical specimens, wood preservatives, deodorant, disinfecting and embalming materials. It is employed as a mordant in printing and dyeing materials, and in the vulcanizing processes of fiber and rubber. It is useful as an electrolyte in dry cell batteries, in metal industry, in galvanizing iron and as an electrolyte for electroplating. It is useful in an organic synthesis, for example in the Friedel-crafts acylation, Fisher indole synthesis, Lucas reagent (zinc chloride with HCl), activation of allylic/benzylic halides towards reaction with olefins or with sodium cyanoborohydride catalyzed reduction of halides, organozinc reagents for use in Negishi coupling, and aldol condensation reactions.
