Gener
al Description and Application
This manual is applicable to both the M1435 and M2827 models. Model specific references in this
manual will be separated by a slash.
The M1435/M2827 Mini-GPUs are specialized switching-mode power supplies 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. Depending upon the model, its
rated output is either 14-volts DC up to 35-amps maximum continuous current (approximately 500
watts), or 28-volts up to 27-amps (approximately 750 watts). The GPU’s intended purpose is to energize
aircraft’s main electrical bus without using the battery or engine. It will safely provide continuous power
for the most delicate electronics and airframe systems up to its full rated output.

Operating Conditions and Limitations
The M1435/2827 is internally fan-cooled and relies on unobstructed ventilation access for proper
operation. The GPU should operate on a clean, hard surface so that debris cannot be ingested. Its
design assumes a dry operating environment. If used outdoors, it is the operator’s responsibility to
ensure that the unit is not exposed to moisture.
The M1435/2827 is designed to provide
airframe
power only
. It is not a battery charger. It does not
monitor the state-of-charge of the aircraft battery. It is not suitable for engine starting.
