Ground Power Unit Aircraft

– Stowage for input and output flexible cables Each aircraft GPU (ground power unit) delivers specified power through the use of a standard electrical system, battery pack and gasoline, diesel or small turbine engine. GPUs have helped to make ground support equipment smaller and increasingly more efficient over the years.

Get The Power You Need With The Help Of Tronair

A gas-powered ground power unit is extremely portable; however, you will have to provide fuel and engine maintenance. Solid state rectifiers or electrical ground power unit models, on the other hand, are much quieter than internal combustion units, producing less pollution overall.

The users of the familiar, traditional diesel engine driven GPU's will recognize the obvious benefits of using an SD 40M series all electric frequency converter GPU: no combustion smells, smoke, fumes toxic emissions or air pollution.

No fuel storage, spillage or bills, no engine start battery or engine maintenance costs. Power Systems International's new product goes one step further. We can now deliver a dual system built into a single enclosure with two 90kVA output circuits.

The new generation of wide-bodied aircraft can now pick up power with two cables from a single location. A direct current (DC) system is similar to that of a car. Typically a 12 or 24V system, a DC ground power unit is used for general aircraft, smaller jets and turboprop airplanes.

Opting For A Used Model

An alternating current (AC) system is more akin to the type of electricity that runs homes and buildings. The AC electrical system runs in the 400 Hz band and is necessary for larger business jets and commercial airliners.

A Transformer Rectifier Unit (TRU) combines the functions of a Transformer and a Rectifier into one unit. In aircraft applications, the TRU converts the 120V AC power generated by the engine or APU generators or provided by a Ground Power Unit (GPU) to 28V DC power for use by various electrical components.

– Analogue metering – 50Hz or 60Hz input frequency – 10 meters flexible input cable – Output contactor with interlock – 10 meters with 400Hz flexible cable aircraft connector - No break power transfer to aircraft

service – Remote monitoring by interface PCB – Fault event logging digital display – RS485 remote monitoring by computer – Second output contactor and interface - Ingress protection IP54 – Line drop compensation - Special paint colors and finishes

Mistakes To Avoid When Purchasing A Gpu

Ground power units require routine maintenance, which equates to occasionally sending them off to a reputable repair facility. This can often cost a pretty penny if your used model winds up having underlying problems — an issue you won't encounter if you go with a new model.

We can also provide a combination system in a single enclosure with a 3 phase 200V 400Hz output. Coupled alongside a secondary output of 28V DC 600Amps with a peak of 2000A for helicopter engine starting and battery charging.

Internal Combustion Vs Electrical Rectifier

Our SD Series product can be plugged into the normal 50Hz or 60Hz mains power source and produces a high stability 400Hz output suitable for most types of passenger aircraft. While it may be tempting to opt for a lower-priced used GPU, this could ultimately be a costly mistake.

Used or refurbished ground power units for aircraft may seem like a good idea, but due to inefficiencies and repairs, you could wind up paying more than you initially would have if you had purchased a new GPU to begin with.

When purchasing a new ground power unit for your aircraft, there are a few all-too-common mistakes that you should avoid. It can be tempting to save money by opting for a used or lower-priced GPU, but understand that there's a reason for that price and you'll most likely wind up losing any cost savings thanks to constant repairs and/or replacements.

Ground power units are designed to last for decades with proper care, thus purchasing a high-quality model will save you unnecessary costs in the long run. When parked on the ground an aircraft cannot use the normal 50Hz (or 60Hz in America) mains power as it needs 400Hz power.

Over-Purchasing Or Under-Purchasing

As a result, airports need specialized ground support equipment (GSE). Ground power units (GPUs) play a vital role in allowing the aircraft to function while on the ground. Our compact dimensioned frequency converters can be fixed to the gantry of a passenger loading bridge.

Alternatively, they can be hung underneath the walkway or simply fixed to a convenient place close to the aircraft. The SD 40M series of frequency converters will accept wide variation in input voltage and frequency and utilize the latest in IGBT power conversion PWM inverter switching technology to provide 400Hz power for all types of passenger aircraft, helicopters and military aircraft of all types with an extremely flexible

, cost effective, energy efficient "point of use" aircraft ground power system for indoor and outdoor applications. GPUs can be powered by internal combustion engines or all-electrical frequency converters (a converter that transforms standard electrical power to AC or DC).

The deciding factor rests with what you're looking to get out of your GPU. Operating internationally, with customers from Japan to the USA, we regularly work with customers who are leaders in their fields. Our focus is always to provide the right solution for our client's, meaning location is less of a concern for us.

Over-purchasing or under-purchasing your GPU can also be an incredibly expensive mistake. If you purchase a unit for a large aircraft when you only need one for a small to medium-sized aircraft, you are over-purchasing and underutilizing, and thus, wasting money.

If you purchase a GPU that isn't adequate for the larger aircraft you work with, you'll wind up not using it at all, another waste of money.
