The Power King 3-Phase 28.5 Volt DC aircraft rectifier/ground power unit (GPU) is designed for in-hangar use or aircraft starting.

The Power King series of ground power units are intended to provide nominal 28 volts DC to power aircraft systems during maintenance and standby conditions. It also relieves the aircraft batteries from the stresses involved in providing high-current engine starting.

You Ask. We Help. Your FAQs on the Power King GPU

Have a question? Just ask us! We would be glad to help.

Do the cables come with hangar and aircraft plugs?
As with all electrical ground power units, this GPU does not come standard with a plug to connect to your hanger. Every hangar or facility is wired differently with lots of different plug choices that could have been installed when the hangar was built. You will need to consult an electrician to determine your 3 phase input voltage and the plug type that is needed. If you know the model number of the plug you need, we can install the plug on the cable for you before it leaves the factory for this unit.

The DC output cable does come with the standard aircraft connector.

Will this unit work on both 50 HZ and 60 HZ 3 phase input voltage?
Yes, this unit can re-wired in your hangar to use any 3 phase input voltage from 208V up to 480V. If you are in Canada and need 575V, please advise at time of requesting a quote. To re-wire the input voltage on the unit, please consult your operating manual.

After talking with our electrician, I only have single phase input voltage? Do you have a unit and what is the difference?
Power King manufacturers a single phase input voltage ground power unit. The single phase unit produces 600 amps continuous and 1200 amps max while the Power King 3 phase input voltage unit produces 1000 amps continuous and 2400 amps max.

What is the warranty?
The manufacturer guarantees the Power King to be free from defective material and workmanship for three (3) years from delivery to customer, with the exception of paint, wheels and power cords.

The warranty does not apply to deficiencies caused by improper use, handling, operation or maintenance. Modifications or unauthorized repairs are considered improper use. Warranty does not apply to any damage due to operation in which the manufacturer instructions are not followed.

NOTE: Warranty terms subject to change. Consult the operating manual for up to date warranty information.

Can I get a 14V switch installed on the unit?
This is an option for the Power King units. We can install a 14V/28V switch on the units as an add on. We caution you that this option uses one cable output so you will need to double check if 14V or 28V is selected prior operating the unit with your aircraft. Operating this unit with an incorrect voltage selected for your aircraft can damage components on your aircraft.

What is soft start on this ground power unit and do I need it?
This is a limiter that can be either added into the power cart during manufacturing or at a later date. It limits the output current of the unit and will allow the voltage to automatically decrease as more current is drawn from the unit. Its purpose is to “soften” the inrush of current when the starter of a turbine engine is first engaged to protect the starter from being over torqued and the solenoid contacts from arcing. Starting current will be limited to approximately 1000 amps when using the “soft start”.

On inrush, the “soft start” drops the voltage as needed to limit the current to around 1000 amps in order to stay connected. As the engine spools up, the voltage will return to 28 volts. On some aircraft, the battery must be turned on in order to be able to inject external power into the start system. In this type of arrangement the aircraft batteries and power cart are in parallel. On a start, the engine draws power from both the batteries and the power cart. If the “soft start” is switched on the batteries will furnish about 80% of the power and the power cart about 20%. With the “soft start” switched in “normal” position, or out of the circuit, the reverse is true, 80% will come from the power cart and 20% from the aircraft batteries as it should. On aircraft where the start can be supplied from external, the power cart will supply 100% of the power.

If I purchase this unit, can I get a PDF manual?
Yes, just email us and we would be glad to send you one.

It was nothing but a pleasure dealing with CGSE. I received my product in a timely manner and the unit was as advertised. I would recommend to anyone in the business of aviation looking for GSE equipment, look no further than CGSE.
4/5
by
Communication from CGSE was great. They were there to answer any questions I had before, during, and after receiving the GPU. The GPU was a little slow due to parts issues. It did take a little over a month to receive it. But once we got it, it has worked great and AMG has been great to work with on questions also.
