Power inverter that changes direct current (DC) to alternating current (AC) while providing voltage stability, low harmonic distortion, good performance in the event of vibration or temperature variation. This device facilitates the connection of equipment that requires the use of alternating current, ensuring its continuous operation so that it does not depend on batteries. The inverter can be attached safely and in an instant in a way that it may be properly located in the aircraft. The Velcro straps on its left and bottom side, allow it to be attached to the structure of the aircraft. In addition, the equipment may be anchored or fixed horizontally or vertically due to its supports on the underside and side faces. The external structure or chassis of the equipment is manufactured with a 14-gauge 7075 aluminum alloy that guarantees its high resistance.
