The new standard in 400Hz Aircraft Ground Power

AERO Specialties, one of the leading providers in aircraft ground power, is proud to introduce the newest version of our 400Hz Solid State Frequency Converter (SSFC), one of the most advanced units in the industry. Tested to the highest standards, the PV90-4 provides the required 400Hz external ground power to support the most sophisticated aircraft electrical demands. The compact design allows for diverse installation applications, from a single output point of use, to a central system supporting multiple 400Hz service points. The rugged stainless-steel enclosure allows the PV90-4 to be configured for fixed applications and a variety of mobile applications for hanger use or outside on the ramp.

Compact, Powerful and Dependable

With hangar and ramp space at a premium, the compact design of the PV90-4 requires a very small footprint to deliver its high-performance output. The high efficiency, unity power factor, and incredible overload features of the PV90-4 ensure your aircraft is supported with the right power.

The large user friendly 5.7” LCD display and oversized control panel makes power selection and system monitoring easy whether indoors or outdoors in bright light.

Modular Design

From conception, the AERO Specialties PV90-4 was designed to be a zero downtime GPU requiring a minimum of planned maintenance. To address this requirement the PV90-4 incorporates a Pluggable Power Module.

This replaceable Power Module reduces the need for in- depth troubleshooting and extended down time by returning the GPU to operation within minutes. This modular design allow technicians without extensive knowledge of 400Hz power conversion to swap out this module as a one-fix solution for almost any fault.

User Interface

The large 5.7” display is designed for the operator.

Large pushbuttons and an intuitive navigation menu allow fast setup and operation. The bright display can be easily read indoors or in direct sunlight.

Complete Support

Maintenance and upgrades to the PV90-4 are simple.

Plug in any USB compatible device to upload software upgrades or download data to assist in remote troubleshooting.


No matter your application, the PV90-4 can be configured to meet your requirements and can also be supplied with an optional 270V DC or 28V DC output for all the below listed configurations.

As a manufacturer and exclusive provider of ground power at major air shows, AERO Specialties engineers have been uniquely placed to operate the company’s converters on all the world’s latest generation aircraft, gaining unrivaled data and experience while working alongside the airframe manufacturers’ test and field engineers. In this respect AERO Specialties is unique.

System operation

  • Input Isolator Switch
    • Fitted with terminal shrouds and mechanical door interlock, this ensures maximum user safety as the door cannot be opened until the switch is in the off position. Once this switch is in the on position, the system is in standby ready for use, no complicated start sequence required!
  • Rectifier
    • The rectifier supplies low ripple DC to the inverter section using rugged 12-pulse technology, the rectifier offers near unity input power factor (> 0.97) with low harmonic content (< 8%).
    • Near Unity Power Factor = Lower input current
    • Low Harmonic Content = Less strain on the electrical infrastructure
  • Inverter
    • The inverter converts the DC supplied from the rectifier into high quality 400Hz AC using the latest PWM technology, the PV90-3 inverter is highly efficient whilst providing a clean output (< 3% THD) suitable for all aircraft.
  • Output Transformer
    • Using high grade steel ensures a compact, lightweight and efficient transformer which acts as a filter and also provides the required galvanic isolation.
  • Output Contactor
    • Complete with interlock, the output contactor ensures power is isolated from the plug until the aircraft is ready to accept power.

Standard features

  • High Overload Capability
    • Modern aircraft demand high overload capability, the PV90-3 offers compatibility with all modern aircraft, in particular: 777/A380/787.
  • Auto Connect
    • After ground support press the on button, the system will run for up to 5 minutes, if during this time the pilot requests ground power, power is automatically connected without any further intervention from ground support.
  • Automatic Line-drop Compensation
    • The automatic line-drop compensation ensures each phase is individually adjusted to achieve the correct voltage at the aircraft plug. The compensation can be adjusted easily via the user interface panel (when in service mode).
  • Remote Control/Monitoring Connections
    • Remote on/off/monitoring allows the system to be controlled and monitored from a distance either from the aircraft plug or via remote switches at the end of a cable carrier system.
  • Filter maintenance
    • Removable polyurethane foam filter cartridge can be replaced whilst GPU running, minimising downtime during routine maintenance.

Modular design

  • Pluggable Power Module
    • One of the most outstanding features of the PV90-3 is the pluggable Power Module. In unlikely event of system failure, the “HEART” of the system can be easily replaced by first line maintenance staff in a matter of minutes.
    • The Power Module contains all power devices and control PCB’s which means there is a one-fix solution for almost any fault. So no matter where you are in the world, repairing the PV-90-3 is possible without the need for site attendance by factory trained engineers.
    • AERO Specialties guarantees turn-around times for warranty repairs of PV90-3 Power Modules and also operate a service exchange system for when your PV90-3’s warranty expires. AERO Specialties recommend one spare Power Module for every 5 systems in operation.
