Mid-Continent True Blue Power Converter 24-32 VDC TC120 6430120-3

Part# 11-19519
MFR Model# 6430120-3


The model TC120 DC/DC Power Converter is a lightweight power converter that translates a direct current (DC) input of 28 volts to an adjustable 5 to 24 volt direct current (DC) output.

The input operating voltage (2432VDC) makes the TC120 suitable for nearly any common general, business, or commercial aviation application and provides an adjustable DC output voltage of 5 to 24 VDC. The unit is rated for a nominal output of 120 watts to power avionics, instrumentation, personal charging, lighting, and many other applications. The TC120 DC/DC Converter is FAA certified to TSO-C71 and tested to rigorous environmental standards and levels of RTCA DO-160G, MIL-STD-810, MIL-STD-704 and MIL-STD-461. 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.

Highlighted features include short circuit protection, overload capability, low input voltage shutdown, temperature monitoring, reverse polarity protection, a self-resettable over-temperature disable and an optional remote enable (on/off) feature.

The TC120 DC/DC converter has a robust Military-rated circular connector and a rugged aluminum case which dissipates heat and provides excellent mechanical strength. It is engineered to require no external cooling and contains no internal fans or cooling methods, which saves energy, reduces weight and allows more Flexible installation locations. At only 11 ounces (312 g), it is lighter and smaller than any other certified solution in the aviation market today.
