ITW GSE 1400

The ITW GSE 1400 is a solid-state 28 VDC GPU designed for aircraft and helicopters whose onboard electrical systems operate at 28 volts direct current. With no rotating parts, the unit eliminates the mechanical wear associated with conventional motor-generator sets, resulting in low noise output and minimal routine maintenance. Continuous current output is available in 400 A and 600 A ratings; each variant provides peak cranking capacity of 1,600 A (400 A model) or 2,400 A (600 A model) to support engine start without drawing down the aircraft's own battery.

The 1400 is available in both mobile and fixed configurations. The mobile variant is lightweight and towable, making it practical for FBO ramps, MRO hangars, and remote stand operations where a powered pit connection is not available. The fixed version suits hangar bays and dedicated parking positions. It powers up and delivers output immediately on connection with a single button press — no warm-up cycle. This class of GPU is the standard choice for turboprop commuters, business jets up to the light-large category, piston twins, and rotary-wing operations that rely on external DC supply during line maintenance, avionics testing, or cold-start engine start procedures. In the GCC context, where many FBO and VIP terminal operations handle Gulfstream, Bombardier, and Dassault fleets, a reliable 28 V supply is a ground-handling baseline requirement.
