Power Electronics Systems – SEMISTACK
1) Currents are calculated for a forced air configuration without thermal stacking, heat sink for SKiiP 3 is PX16, with SKF16B fan.
First value: Maximal permanent current without overload; Second value: nominal current, with 150 % overload at 2 Hz (U/f constant)
Ratings are: Vdc = 350, 540 or 950 Vdc, switching frequency = 3 kHz, ambient temperature = 35 °C, Vac = 230, 400 or 690 VRMS sinus output current
2) Power rating is for a cos ϕ = 0,85 and constant nominal conditions
