White Lightning M2850 50-amp 28-volt GPU with 3-pin Oval Plug
MFR Model# M2850
Overview
| The M2850 Mini-GPU is a specialized switching-mode power supply designed to provide pilots and aviation maintenance professionals with a portable, affordable source of stable, high-current, noise-free DC power that replicates the in-flight electrical environment. Its rated output is 28-volts up to 50-amps (approximately 1500 watts). The GPU’s intended purpose is to energize an aircraft’s main electrical bus without using the ship’s battery or engine. It will safely provide continuous power for the most delicate electronics and airframe systems up to its full rated output. |
Features
- Color-coded, keyed SB-50 type output connection to prevent accidental voltage mismatch. RED designates 24/28 volt compatibility.
- Digital output meter shows voltage and amperage (load)
- Front panel status indicator LED
- Programmable auto-shutdown timer and dual USB power ports for mobile device charging
- QuietFiltered output for interference-free COM radio operation
- Auto protection/recovery from short circuit, reverse polarity, over voltage/load/temperature

No, this is used for maintenance and avionics/electrical testing. This GPU delivers power to the bus and bypasses the battery.
Per the manufacturer, "a gear swing would be okay, so long as there were not a number of other stacked functions going on (thereby requiring more amps)."
