Page 5: Section 1 General Description
SECTION 1 GENERAL DESCRIPTION INTRODUCTION The model TC280 Series Static Electrical Power Converter is a lightweight power converter that translates an alternating current (AC) input of 115 volts at 350-800 Hertz to a 28 volt direct current (DC) output. The wide input operating voltage and frequency make the TC280 suitable for nearly any common business or commercial aircraft which provides 100-125 VAC between 350-800 Hertz. -

Input Current (full load): 2.8 Amps nominal; 4.4 Amps max Input Current (unit off): 400 milliamps Recommended Input Circuit Breaker: 5 Amps Output Voltage: 28VDC ± 0.5 VDC Output Power: 280 watts (28VDC @ 10 Amps rated) Efficiency: 88% nominal... -
Page 7: Section 2 Pre-Installation Considerations
SECTION 2 PRE-INSTALLATION CONSIDERATIONS COOLING The TC280 Series 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). -
Page 8: Section 3 Installation Procedures
This section contains interconnect diagrams, mounting dimensions and other information pertaining to the installation of the TC280 Series Static Converter. After installation of cabling and before installation of the equipment, ensure that power is applied only to the pins specified in the interconnect diagram. - Page 9 Examples are shown in Figures 3.4 and 3.5. Harness Verification With the TC280 Series Static Converter disconnected, activate the aircraft power bus that supplies the unit and use a multi-meter to verify that aircraft power and ground with appropriate voltage is on the pins within the mating harness.

SECTION 4 OPERATION ELECTRICAL PERFORMANCE The TC280 Series Static Converter converts an alternating current (AC) voltage input to a regulated VDC output. See Table 4.1 specific output and input frequency. Model Input Frequency Output TC280 115 VAC 350-800 Hz 28 VDC Table 4.1... - Page 13 Short Circuit and Over-Current The TC280 Series Static Converter is capable of surviving a short circuit or over-current event without permanent damage or effect to long-term reliability. The unit can provide over its rated power output up to 308 watts for over 30 minutes (until over-temperature shutdown occurs).
