Info

Gate driver card A001 LED info A001 Gate driver card has several LEDs to show basic information of cards functions and states. LEDs H1, H4, H5 and H6 shows if IGBT can have control signals. LEDs H7 and H8 show if there is feeder unit connected and if data is available in CAN bus. LEDs H2 and H3 shows if there is needed control voltages from cards own PSU. H1 IGBT gate pulses H4 IGBT gate pulses H5 IGBT gate pulses H6 IGBT gate pulses H7 Remote control unit connected H8 Data communication H2 +5V H3 +15V
