Reliable aviation equipment engineered for extreme reliability, energy efficiency, and low maintenance overheads.
Aircraft on the ground require a continuous, highly stable, and specific electrical supply to power environmental control systems (ECS), avionics suites, radar networks, and interior lighting without engaging their auxiliary power units (APUs). Operating an onboard APU on the apron is increasingly discouraged globally due to high jet fuel consumption, significant carbon emissions, noise pollution, and accelerated mechanical wear.
The 90 kVA 400 Hz Ground Power Unit (GPU) acts as the industry standard benchmark for narrowbody and regional commercial aircraft—such as the Boeing 737 series, Airbus A320 families, and various Embraer E-Jets. Delivering exactly 400 Hz AC power at a nominal 115/200V configuration, these units bridge the gap between municipal grid networks (typically 50/60 Hz) and the highly sensitive power demands of modern airframes.
Engineered to operate in demanding airfield environments, our 90 kVA units feature dual output pathways, low total harmonic distortion (THD < 2%), and rapid transient recovery rates. Standard solid-state conversions utilize state-of-the-art Double Conversion topology.
Pioneering the paradigm shift from mechanical rotary generators to digitalized, solid-state, and hybrid-battery systems.
Eliminating moving parts drastically lowers maintenance requirements. Employing insulated gate bipolar transistor (IGBT) technologies, modern static converters are quiet, zero-emission systems ideal for fixed bridge installations (under-bridge configurations) or towable carts.
The clean energy revolution has brought lithium iron phosphate (LFP) systems to the tarmac. Towable energy storage GPUs charge during off-peak hours from the grid and discharge silently on the apron, achieving 100% emission-free aircraft turnaround schedules.
Connecting GPUs to centralized airport databases (AODB) allows predictive startup, automatic power-off, and real-time remote diagnostics. Fleet managers track peak power draw, energy utilization indexes, and fault isolation logs in real time via Cloud dashboards.

Partnering with airport authorities and aviation logistics networks to support clean, reliable operations.
By coupling fixed-bridge solid-state 90 kVA converters with Pre-Conditioned Air (PCA) units, airport gates can bypass onboard APUs entirely. Research indicates a single gate electrification project reduces local nitrogen oxide (NOx) output by up to 90% and cuts annual operating carbon footprints by hundreds of tons per gate, helping airports meet international climate goals.
Utilizing our battery-based towable GPUs helps isolate local airport power grids from high peak demand cycles. During peak hours, ground crews can run equipment from battery units, drawing recharging current from the main grid only during off-peak times. This peak-shaving capability reduces energy costs and minimizes utility grid stress.

High-frequency AC power (400 Hz) allows aircraft transformers and alternators to be built significantly smaller and lighter than standard 50 Hz or 60 Hz commercial systems. This design saves weight, optimizing fuel efficiency and payload capacity during flight.
Solid-state GPUs convert utility power using digital switching technology without moving parts, which reduces mechanical wear, noise, and maintenance requirements. Rotary generators use a mechanical motor to turn a generator shaft, which requires regular maintenance but may be preferred in extreme electrical environments.
A 90 kVA GPU is generally designed to support narrowbody and regional aircraft (such as the Airbus A320 or Boeing 737). Widebody aircraft (like the Boeing 777 or Airbus A350) typically require dual-output systems or multiple units connected in parallel to provide 180 kVA or more.
Battery-powered GPUs draw zero fuel on the ramp and operate with very low noise. When charged with clean grid energy, they help eliminate ground-level emissions during aircraft turnarounds.
Our production lines support a wide range of input configurations—including 380V, 400V, 415V, and 480V AC at either 50Hz or 60Hz. We can customize input electrical parameters to match the utility standards of your region.
