DRS Technologies 30KW Advanced Mobile Electric
Power Distribution System, (AMEPDIS) is a digitally
controlled highly ruggedized power distribution unit.
It provides a safe and reliable method of power
distribution with increased capability over standard
power distribution units. Designed for the USMC, it
is interoperable with currently fielded MEPDISR-R
power distribution systems to work as part of a larger
electrical grid. The 30KW AMEPDIS unit is a 120/208
VAC, 60 Hz, 3 phase system that accepts multiple AC
electrical inputs from larger power distribution units
(PDUs) as well as single or paralleled power generation
sources.
Through the digital interface, AMEPDIS is able to
display operational parameters, such as voltage,
frequency, current, and power for each input, output,
and for the overall system. All warnings and faults
are annunciated via text and by flashing the display
backlight. All advanced features such as circuit breaker
trip curves, current limits, and the enabling/disabling
of load shedding and phase balancing are accessed
via the HMI. To reduce setup time, the unit can be
operated in manual mode while being configured. When
configuration is complete, the operator can enable
these features
without shutting down the unit, allowing for seamless
transfer from manual to advanced operation.
The output breakers are operated by the control
system and have the ability to be turned on and off.
Trip curves and current limits of each output can be
individually adjusted via the HMI. System safety is built
in to prevent users from accidently exceeding hardware
limitations. In the event of a failure of the control
system, the circuit breakers will still trip according to
the connector rating.
The load shedding and prioritization feature will
ensure the most critical loads, as determined by the
user, remain powered in the event that overall load
demand exceeds power generation capacity and will
automatically reconnect them as the power becomes
available.
Phase balancing is handled automatically by the
30KW AMEPDIS unit. The three single phase outputs
are shifted accordingly to minimize or eliminate
imbalance. Phase balancing also helps to prevent the
input breakers from tripping due to a single phase
being overloaded. Fuel savings can also be realized as
balancing the phases leads to increased fuel efficiency
from the attached generators.
