Today’s modern aircraft has specific needs when it comes to electric power. For example, a large jet must have self contained power for the flight instruments, environmental control systems, galley, lighting, and passenger entertainment systems. These systems are complex and some of them run on high frequency, three phase, 400HZ power. It takes special equipment to service this kind of system, and Hobart Ground Power is leading the way.
Why 400 HZ AC Power?
Standard power operates at 60 hertz or cycles per second. If aircraft used 60 HZ power, they would require very large transformers for energy storage. Because high frequency power is more efficient, smaller transformers can be utilized and this saves a great deal of aircraft weight, which is highly important.
DC Current
Some parts of modern aircraft operate on direct current, and this is why Hobart Ground Power provides GPUs with the capability of producing both direct and alternating current.
The Important Role of the Ground Power Unit
The GPU is very important for aircraft maintenance crew. While a large air vessel is sitting, it has no way of generating the power it needs to operate the electrical system. Many times, maintenance crews must test these systems to make sure they are functioning. In addition, if repairs, upgrades, or replacements must be made, it is vital to ensure these systems are fully operational before the plane leaves the ground.
The GPU provides power to the aircraft and this is usually done with three phase alternating current of 115 volts at 400 hertz. In addition, the ground power unit must also be capable of providing the necessary DC current to the aircraft. GPU equipment is portable and attaches to the aircraft electrical system through a special port.
Why Choose Hobart Ground Power?
Hobart supplies 400 HZ systems that meet or exceed the current and future needs of the aircraft industry. Their ground power units are made to exact specifications and under the strictest of quality control conditions. In fact, they are a certified ISO 9001 manufacturer.
What is ISO 9001?
ISO 9001 is a quality control certification issued to manufacturers which have met very high stands of quality. Companies must use an efficient quality management system which oversees every aspect of production.
Are There GPUs Comparable to Hobart Ground Power?
Some companies are choosing high quality GPU equipment from TLD. They manufacturer very dependable units and are well respected within the industry.
