Unitron LP
“A Powerful Team in Aviation Support.”
Unitron's aviation footprint is split between three distinct GCC buyer profiles: (1) airline ground handlers at hub airports needing 400Hz/28VDC mobile and fixed GPUs that survive 50°C+ ambient temperatures, (2) defence operators specifying MIL-spec ground power for fighter and rotary fleets — including the 270VDC supply that newer F-35-class platforms require, and (3) corporate aviation FBOs running FoxCart® 28VDC carts for business jets. The single Dallas facility manufactures all converter classes from 20 kVA portable to 180 kVA fixed-line, ships globally with 24-hour service-call turnaround, and is one of a small number of suppliers manufacturing the full 400Hz/28VDC/270VDC stack under one roof.
تنقسم بصمة Unitron في الطيران إلى ثلاث شرائح مشترين متمايزة في الخليج: (1) مشغّلو الخدمات الأرضية في مطارات المحاور الذين يحتاجون وحدات GPU بقدرة 400 هرتز و28 فولت مستمر متنقّلة وثابتة تتحمّل درجات حرارة تتجاوز 50 درجة مئوية، (2) المشغّلون الدفاعيون الذين يطلبون طاقة أرضية بمواصفات عسكرية للطائرات المقاتلة والمروحية، بما في ذلك إمدادات 270 فولت مستمر التي تتطلّبها منصّات الجيل الجديد من فئة F-35، (3) شركات الطيران الخاص (FBO) التي تشغّل عربات FoxCart® بقدرة 28 فولت مستمر للطائرات النفاثة. تُصنّع المنشأة الوحيدة في دالاس جميع فئات المحوّلات من 20 كيلو فولت أمبير محمولة إلى 180 كيلو فولت أمبير ثابتة، وتشحن عالميًا مع استجابة خدمية خلال 24 ساعة، وهي واحدة من قلّة من المورّدين الذين يصنّعون كامل منظومة 400 هرتز / 28 فولت مستمر / 270 فولت مستمر تحت سقف واحد.

Where Unitron wins for aviation buyers.
400Hz GPU for narrow-body turnaround
Solid-state 90-180 kVA fixed-line 400Hz converters serve the gate-power requirement for A320/737-class fleets at GCC hubs. No rotating machinery means lower maintenance overhead vs legacy motor-generator GPUs and stable frequency under heavy resistive load — important when a single hub powers 20+ simultaneous turnarounds.
Mobile 28VDC for corporate aviation
FoxCart® 28VDC carts have powered corporate aviation since 1970 and remain the de-facto reference for FBO ground power on Gulfstream, Falcon, Bombardier and Embraer platforms. Built for high-ambient operation — the cart will start a soaked airframe in 50°C apron heat without thermal derating.
270VDC ground power for F-35-class platforms
Newer combat aircraft (F-35, advanced rotary platforms) specify 270VDC bus voltage. Unitron is one of a small number of US suppliers manufacturing both 28VDC and 270VDC converters under one roof — useful for mixed fleets and for GCC defence operators standardising on a single ground-power vendor across aircraft generations.
Combo 400Hz / 28VDC / 270VDC unit — fleet flex
Single combo unit handles 400Hz frequency conversion plus 28VDC and 270VDC outputs. Reduces ground-equipment count on operators running narrow-body, wide-body, and military rotary all from the same ramp — common at GCC operators with mixed civil/defence portfolios.
