30 kW AMEPDIS
HDT Global’s 30 kW Advanced Mobile Electric Power Distribution System (AMEPDIS) is a digitally controlled, highly ruggedized power distribution unit. 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 30 kW AMEPDIS unit is a 120/208VAC, 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 displays 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 control panel. 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 can be turned on and off. Trip curves and current limits of each output can be individually adjusted via the control panel. System safety is built in to prevent users from accidentally exceeding hardware limitations. In the event of a control system failure, 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 30 kW AMEPDIS unit. The three single phase outputs are shifted accordingly to minimize or eliminate imbalance. Phase balancing helps to prevent the input breakers from tripping due to a single phase being overloaded and increases fuel savings by running attached generators efficiently.
