Page 5: General Description
SECTION 1 GENERAL DESCRIPTION INTRODUCTION The model TC234 DC/DC Power Converter is a lightweight power converter that translates a direct current (DC) input of 14 volts to an output of 28 volts direct current (DC) output. The input operating voltage (11-18 VDC) makes the TC234 suitable for nearly any common general, business, or commercial aviation application. -
Page 6: Cooling
Table 1.3 SECTION 2 PRE-INSTALLATION CONSIDERATIONS COOLING The TC234 product does not require external cooling or contain internal active cooling. Cooling of the unit occurs exclusively through passive conduction through the base or radiated cooling across the metal case. Additional cooling can be realized through convection (exposure to free moving air) or conduction (mounting to a thermally conductive metal surface). -
