The D-180, a diesel-powered, trailer-mounted, 180kVA ground power unit from JBT AeroTech can continuously supply the 180 kiloWatt service. 400 Hz power is produced from a diesel engine-generator combination available in either Tier 3 or Tier 4 configurations that meet the most stringent environmental requirements. The unit is designed for ease of access for all preventive and intermediate maintenance operations. The frame and shell are made of heavy duty materials, and controls feature a HMI console able to provide critical operational and diagnostic information to operators and maintenance personnel. HMI digital displays record engine performance data, relevant maintenance and diagnostic data, as well as key operational metrics such as fuel status, voltages, amperages, frequencies, kiloWatts, run times, and unit status
