28VDC Power Supplies

MCM Engineering offers 28VDC Power Supply’s designed for use with parked aircraft requiring 28VDC ground power. The Power Supply is used in conjunction with a 400Hz power source, transforming 400Hz, 115VAC power to 28VDC.

MCM 28VDC Power Supply’s can be fixed or moved (portable configuration) from gate to gate allowing the unit to be placed in close proximity to the aircraft position insuring a minimal DC voltage drop ultimately improving the quality of power delivered.

28VDC Power Supply’s come complete with a voltmeter, ammeter and protective circuits.

The MCM 28VDC Power Supply is the perfect piece of equipment for supporting your commercial and military traffic requiring 28VDC ground power.
