Experience You Can Count On
Controlled Systems was founded in 1972 upon a commitment to provide the highest quality products and absolute excellence in service. Our goal was to build lasting customer relationships and ultimately, to be the number one choice for power conversion and aircraft support products in every market we serve. While times have changed, so has our business – but these principles remain as important now as they did more than 30 years ago. It is our passion and commitment to these principles that is the foundation of our business and it is the very reason we have been a leading aircraft and ground based power conversion systems provider throughout our history.

Controlled Systems’ 400Hz frequency converter utilizes the latest
state of the art power conversion control and power switching,
providing the ultimate in ground power support. The evolution of
true DSP digital control enables Controlled Systems to provide ultra
clean, precision 400Hz power as well as monitoring and diagnostics.
The frequency converters can be provided with a wide range of input
and output voltages, for global application requirements. Controlled
Systems has frequency converters sized to suit the customer’s
requirements, ranging from 1kVA to 1000kVA and above. Standard
industry sizes and configurations are offered, as well as custom sizes
and custom layouts for specialized ground power needs. The
frequency converter can be packaged to suit all environmental
conditions through NEMA standards 1, 12, 3R, 4, 4X and 3R/4X
enclosures. Our support team will assist in developing frequency
converter equipment to meet all your specific requirements.

Controlled Systems applies the same state of the art technology
found in the 400Hz equipment to its 50/60Hz power conversion
equipment. The robust design of the 50/60Hz frequency
converter provides our customers with reliable trouble free
power for the life of the application. The frequency converters
can supply converted power for either an individual application,
or system design utilizing multiple outputs. The latest
generation Controlled Systems frequency converter can be
paralleled for redundant power system operation, with
communication link capability for power monitoring. This
communication ability provides the customer with an
information base for today’s power monitoring software.
To keep pace with changing aircraft design and
increased regional airline growth, Controlled Systems
has met the demand with D/C Power Supplies,
designed with high performance power in mind.
The D/C Power Supply can be supplied as a stand-
alone unit or in combination with a 400Hz or other
power systems, to best serve the customer’s
requirements.
Controlled Systems’ D/C Power Supplies are available
in the following output configurations:
270 VDC Power Supplies
28 VDC Power Supplies
24 VDC Power Supplies
We have
a wide variety of input voltages for global applications. |

Controlled Systems utilizes single jacket, multi-
conductor, low inductance 400Hz aircraft ground power
cable. This offers significant advantages over
cumbersome cabling made up of numerous single
conductors banded together. The unique design has a
patented cable head, whereby the nose and the power
pins are separate, allowing replacement of the nose or
any of the six pins individually. Subsequently, this
provides lower repair and maintenance costs. The
Controlled Systems 400Hz aircraft service cable is the
optimum choice for use at commercial terminals, military
parking aprons, hangars and test labs & shops.
Controlled Systems’ Line Drop Compensators (LDC)
is designed to maintain unity power factor for 400Hz
ground power distribution systems. The LDC
maintains a stable line voltage between the
centralized power source, (Frequency Converter),
and the aircraft’s input receptacle. Controlled
Systems’ LDC automatically adjusts capacitive
reactance to the circuit in order to cancel inductive
reactance of the transmission system to prevent
“Line Drop” occurrences. Controlled Systems’ LDC
incorporates “Non-PCB”, oil filled tube capacitors and
are built with tap settings to fine tune each circuit.
The LDC is suitable for indoor or outdoor
applications and can be stacked or incorporated into
central distribution switchgear.
Controlled Systems utilizes many forms of aircraft cable
storage and deployment devices to fit all customer
applications. Our cable hoist is designed for ease of
installation and reduced maintenance. The hoist can be
mounted on the side of a boarding bridge cab or from the
ceiling of an aircraft maintenance hanger. Controlled
Systems also supplies cable reels, both spring and motor
driven for retraction and
deployment of aircraft cable.
These cable reels can be used
on floor applications as well
as suspended from aircraft
maintenance hangar ceilings.
Controlled Systems provides a
heavy-duty aircraft cable rack
in both floor and wall mount
designs. Controlled Systems can provide cable retrievers
for ease of deployment and proper storage. The cable
retrievers are motor driven and are designed to coil the
aircraft cable so that harmful twists and knots due not
occur during the retrieval process.

The Motor Generator (MG) equipment
distributed by Controlled Systems, has
been used in the aviation industry for
decades, and continues to be a reliable
choice throughout the generator-
orientated industry. The proven long-life
history from the rugged design of rotary
generators provides another power
conversion option.

Controlled Systems designs, and
manufacturers 50/60Hz, 400Hz and D/C
distribution equipment, to support the
wide range of power conversion
equipment offered. This equipment
utilizes latest technology in solid-state
protection devices, and proven
technology in 400Hz and D/C control
and distribution. The benefit of
designing and manufacturing both power conversion equipment, and related
distribution equipment, is to provide complete control over application
criteria, quality control and project management. Through the integration of
power supply and distribution, Controlled Systems provides the end user
with a system that is low cost, reliable, and innovative, meeting the stringent
applications of the aviation market

Controlled Systems chopper rectifier designs consist of high frequency switching technology in a modular design package that converts the secondary AC voltage to a regulated output DC voltage. Larger power systems are constructed of multiple chopper modules to obtain the specified current requirements. Each section of modules has a separate set of sensing and protection and receives directions from the main chopper controller. This chopper conversion process has minimal effect on the incoming power system and a high power factor is maintained at the level of a fixed diode converter. The transformer section is configured to optimize the harmonics. The total module count usually results in a 12 pulse configuration as seen by the utility. The load sees a very smooth low ripple DC over the total range due to compact high frequency output filtering. Controlled Systems designs and manufactures all the water-cooled IGBT power modules used in our chopper rectifiers. A full control metering, monitoring, and fast protection scheme is integral to all Controlled Systems chopper rectifiers |
