    1.1 - GENERAL 1.1.1 - PRESENTATION The “JET-POWER FILTER II” is a static GPU designed to provide ground power for maintenance and startup of aircraft having 28 VDC electrical systems. The “JET-POWER FILTER II” changes alternating current at its input to a continuous current of 28V (adjustable on panel) by using its trans- former and six-phase rectification.

  • Page 5: Technical Information

     220V (Brazil);  208V (USA);  Three-phase, no phase sequence. NOTE: The neutral of “JET-POWER FILTER II” is the BLUE cable. 1.1.2.2 - 1 OUTPUT (Plug for Output Source) It is located on the left front side, coming directly from inside the source, providing 24 to 33 VDC, depending on how the seven position switch (front panel) is set.
  • Page 6  The current can be limited to 30, 50, 100, 200, 300, 400, 500, 750, 1000, 1500 e 2000A. NOTE: The “JET-POWER FILTER II” is equipped with an electronic circuit adjustable up to 11 positions. It turns off the source when the current set at knob is reached.
