1.5 Power Up Procedure

  1. Check that GaN card, C2000 control card and bias card are plugged in correctly and tightly.
  2. Use an external fan for cooling during test.
  3. Use current probe to monitor AC input current. Use voltage meter to measure DC output voltage.
  4. Connect a high voltage load to DC output. Set load to 0.1A. Turn on load.
  5. Connect AC source to AC input.
  6. Set AC output at 115V-60Hz, or 230V-50Hz. Turn on AC. DC output voltage is regulated at about 385V.
  7. Gradually increase load. Full load: 1.8kW at 115VAC, 3.6kW at 230VAC.
