JTL28R, solid state GPU provides a quiet, perfectly regulated 28.5 volts DC current for use in hangar or aircraft side on the ramp. These reliable GPUs were specifically developed in response to customer needs for fully regulated, dependable power required by today’s most modern aircraft.
     The JTL28R is available with “soft start” mode (option) for engine starting when the current limiting mode recommended for the aircraft type. JTL28R GPU will easily deliver 800 continuous amperes with capacity for up to 2,400 amperes peak starting current.
