White Lightning GPU 12/14V (2 Pin, Piper Plug)

Safe, Affordable, Airframe Power

The White Lightning Mini-GPU achieves a remarkable 88% efficiency to provide up to 35A of power at 14.25 volts DC, perfectly replicating the in-flight electrical environment. Its cool running, switching-mode power modules provide massive amounts of stable, noise-free power, compatible with input voltages from all over the world. It will continuously power the most delicate avionics and airframe systems without risk of depleting the ship’s battery or causing costly damage.

This Model M1435P comes with a 8’ airframe output cable with yellow SB50 connector that protect from damage due to accidental voltage mismatch. The 2-pin “Piper” circular plug connects to the aircraft.

Frequently Asked Questions

Q: Can I use the M1435P to start an aircraft engine?

A: The M1435P GPU is inadequate for piston and turbine engine starting and should be used for airframe systems power only.

Q: How does the M1435P connect to my aircraft?

A: The Model M1435P Mini-GPU includes a 8’ output cable with yellow SB50 plug on the GPU end, and a 2-pin “Piper” oval plug that connects the GPU to the aircraft.

Q: What if I need a longer output cable for my situation?

A: The 8’ output cable, with yellow SB50 plug, can be extended/doubled by adding an extra output cable with yellow SB50 plugs on both ends. These are available as a replacement part. Contact Audio Authority tech support for assistance.

Q: Can the M1435P be used with certified aircraft?

A: Yes, the Model M1435P Mini-GPU is compatible with certified aircraft that have a 12V battery and a 14V electrical/charging system. However, its output cable is incompatible with the external power receptacle on certified aircraft. You must purchase a different output cable with the appropriate plug.

Q: Can I use the M1435 to charge my battery?

A: The Model M1435P Mini-GPU is not designed for long-term battery charging. It has no circuitry for monitoring the battery’s state of charge or determining the precise charging voltage for various battery conditions and ambient temperature. So, the general answer is no. However, for short periods of time (an hour or two), the GPU’s output can be used to “top-off” the charge of a battery that is NOT severely discharged. This is particularly useful during a powered preflight, allowing the pilot to take his/her time to check every airframe system and lights for proper operation without depleting the starting battery.

To optimize battery capacity and reliability, we highly recommend full-time, maintenance charging desulfation, and recovery. Our preference is the aviation specific BatteryMINDer products by VDC Electronics. The BatteryMINDer is designed to remain connected for long periods of time and will never overcharge or damage your battery.

Q: Does the GPU work outside North America?

A: Yes, the input voltage and frequency ranges are very wide and universal for worldwide operation: 85-264 VAC, 47-63 Hz. The AC cord supplied is a North American grounded 5-15, which can be adapted, or replaced with an appropriate cord, sourced locally.
