Goods description
Proizvod (tzv."inverterska jedinica"), "frekventni regulator" smešten u plasticnom kucištu približnih dimenzija 15 x 10 x 6 cm. Sastoji se od štampane ploce na kojoj se nalaze ugradeni aktivni i pasivni elementi. Indukcioni kalemovi, kao naponski filteri za ulazno (AC) napajanje 120 V, frekvencije 60 Hz, naizmenicni napon dovode do statickog konvertora koji ga pretvara u u jednosmerni napon (AC/DC). Takav napon se preko pasivnih elemenata (kondenzatora, otpornika...) dovodi do 3 para invertora u kojima se se jednosmerna struja pretvara u naizmenicnu struju napona 120 V (DC/AC) i frekvencije 0 - 200 Hz. Promena frekvencije se vrši preko upravljacke elektronike (elektronskih integralnih kola), koja imaju sopstveno napajanje ugradeno na ploci. Na kucištu proizvoda je izveden prikljucak kojim se direktno povezuje na pinove kompresora rashladnih uredaja ciji broj obrtaja zavisi od kontrolisane vrednosti frekvencije koju uredaj daje.
