Kakva je situacija sa snabdevanjem električne energije, sigurno da ne želite da ostavite svoj posao ili bilo kakvu aktivnost na milost i nemilost elektrodistribuciji. Ili, jednostavno Vam treba izvor naizmenične struje tako gde ga nema, na izletu ili van zgrade.

Jedno od zaštitnih rešenja su UPS uređaji. Oni sprečavaju da u slučaju nestanka električne energije Vaš rad na računaru propadne. Njihova jedina "mana" je što mogu da rade svega 5-10 minuta.

Drugo rešenje je pretvarač. Mi u "Radio klub"-u već skoro dvadeset godina, imamo sve ključne računare, telefax i telefonsku centralu kao i sistem rezervnog osvetljenja, vezane na pretvarač. Jednostavno, bilo bi ružno da dočekamo kupce u mraku sa izvinjenjem tipa "Izvin'te, nestalo struje, dođite sutra".

Od skoro, u našoj ponudi imamo pretvarače firme HQ snage 300W do 1700W. Ulazni napon im je 12V DC - iz akumulatora, a izlazni 230V AC, sa modifikovanom sinusoidom. Opremljeni su sa "E-mark" sertifikatom, neophodnim za ovakve uređaje u Evropskoj uniji od oktobra 2002. godine.

Pored ovih pretvarača, koji nemaju svoj punjač akumulatora, imamo i modele sa ugrađenim automatskim punjačem akumulatora.

Za kraj, pored ovih pretvarača sa modifikovanom sinusoidom, imamo i pretvarač sa PRAVOM sinusoidom, neophodan za rad mnogih uređaja. Trenutno imamo u ponudi samo model, izlazne snage 300W, ali u budućnosti očekujemo i jače modele.
