14.05.1989. Zagreb, Yugoslavia (later Croatia) Marko Štetić founded crafts for development and production of power electronics devices. The first products are: - AC/DC power supply with constant output current, - rectifier 220 VAC / 48 VDC-4 A, - DC / DC converter 48 VDC / 24 VDC - 200 W, - multi-output DC / DC converter 48 VDC / 5VDC, 24 VDC, +/- 15 VDC, - voltage stabilized 140 – 260 VAC / 220 VAC +/-5 %. Switching technology is being used (30 up to 100 kHz) by using MOSFET
