400 Hz AC + 28.5 V DC Ground Power, wherever fixed infrastructure is not available
The APA-110 series series is a trailer-mounted, diesel engine driven mobile GPU designed to provide stable aircraft electrical power at remote stands, operating bases, and sites with limited or no apron power. It is also available with plug-in function, enabling full aircraft servicing at remote stands and operating bases, as well as emissions-free use inside aircraft hangars. The platform is available in multiple configurations: 400Hz (EAC) and 28.5V DC (EACR), allowing you to match the unit to fleet requirements and operational profile.
APA-110 available configuration options
Choose the configuration that matches your AC or AC+DC requirements, including DC engine-start support where needed:
- APA-110 (EAC-60) – 400 Hz AC, 60 kVA
- APA-110 (EAC-90) – 400 Hz AC, 90 kVA
- APA-110 (EAR-800) – 28.5 V DC 800 A
- APA-110 (EACR-60/300) – 400 Hz AC 60 kVA + 28.5 V DC 300 A
- APA-110 (EACR-90/800) – 400 Hz AC 90 kVA + 28.5 V DC 800 A
All configurations share the same rugged diesel platform, IP55 protection, and advanced control & protection architecture.
Main specifications (APA-110 series)
🔹 Output (AC): 400 Hz, 3×115/200 VAC (PE) — available in 60 kVA or 90 kVA configurations

🔹 Mobile platform: towable trailer chassis/truck mounted, composite casing
Why choose APA-110?
🔹 Mobile 400 Hz power where fixed infrastructure doesn’t exist , — remote stands, bases, temporary locations
🔹 Configuration flexibility: pick 400Hz (EAC) or A400Hz+28.5 V DC (EACR) to match your aircraft and mission profile
🔹 Built-in protection & safety: overload, over/under voltage, over/under frequency, short-circuit, overheating + emergency stop
🔹 Designed for harsh conditions: IP55 enclosure + wide temperature/humidity range
🔹 Serviceability for long life: diesel-driven platform with strong after-sales logic (documentation, training, spares support)
🔹 Operational confidence: stable output and power quality to protect aircraft systems and standardize ground procedures
Use cases
🔹 Remote stands and aprons where fixed 400 Hz infrastructure is unavailable
🔹 Airfields with limited or no grid access (mobile power for day-to-day operations)
🔹MRO hangars and maintenance bays needing reliable ground power during checks and troubleshooting
🔹Military bases and deployment locations requiring rugged, towable support equipment
🔹Backup / contingency GPU for airports to maintain operations during outages or peak load periods
🔹Mixed fleet operations where both 400 Hz and 400 Hz + 28.5 VDC capability may be required (depending on configuration)
