ITW GSE 2400 Compact 400 Hz

The ITW GSE 2400 Compact is a solid-state 400 Hz frequency converter designed for point-of-use deployment on boarding bridges and apron positions. The range spans 30, 45, 60, 90, 120, and 140 kVA, allowing a single model family to cover regional jets through wide-body aircraft including the Airbus A380, A350, and Boeing 787. Output is 3 × 115/200 V at 400 Hz ± 0.1 %, and the ITW GSE Plug & Play voltage compensation system maintains regulated voltage at the aircraft plug regardless of cable length or load imbalance — a meaningful advantage over older transformer-rectifier designs where voltage quality degrades at the end of long cable runs.

With no rotating parts, the solid-state converter eliminates oil changes, brush replacement, and the mechanical failure modes that drive unscheduled maintenance on motor-generator GPUs. The 400% standard overload rating handles the transient current demand of aircraft avionics initialisation and galley loading spikes without tripping. The unit is tested to ISO 6858 sections 1–8, verified under 56 °C ambient conditions, and is EcoGate-enabled for integration with Intelligent Power Management infrastructure. Individual phase regulation provides true phase-by-phase voltage control, which matters for modern fly-by-wire aircraft with asymmetric phase loads. Its compact footprint makes it suited for both bridge-mounting and above-pit fixed positions at high-density gates. The 2400 Compact is ITW GSE's mainstream commercial GPU for new-build and retrofit gate programmes.
