Page 5: General Description
115VAC. The MD50 series Inverter is FAA certified to TSO C73 and tested to rigorous environmental standards and levels of RTCA DO-160. The small size and light weight in conjunction with its installation flexibility inside or outside the pressure vessel make it an ideal choice for aircraft power needs while reducing the challenges associated with other similar products. -
Page 6: Cooling
SECTION 2 PRE-INSTALLATION CONSIDERATIONS COOLING No external cooling is required. The unit is equipped with two internal brushless DC fans. Restriction to airflow can cause overheating of the unit and limit performance or reduce the expected life of the product. Make sure to provide adequate clearance on both ends of the unit with the hexagonal openings to allow for proper circulation. -
