  • Page 7: Section 2 Pre-Installation Considerations

    SECTION 2 PRE-INSTALLATION CONSIDERATIONS COOLING The TI250 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 convective effects of the environment (exposure to free moving air).

    MODIFICATION This product has a nameplate that identifies the manufacturer, part number, description, certification(s) and technical specifications of the unit. It also includes the “MOD” or modification number representing notable changes in the hardware design of the unit. Modification (MOD) 0 is the initial release of the product and is identified on the nameplate by the lack of marking on the MOD numbers 1 through 9 (i.e.

  • Page 14: Mounting

    Refer to Section 2: Pre-Installation Considerations in regards to equipment location. The TI250 Series Static Inverter is designed for base mounting only. Four #10 mounting holes should be provided in the aircraft in accordance with Figure 3.5. Secure the unit with four #10 pan head Phillips screws, or equivalent.
  • Page 15: Installation Caution

    INSTALLATION CAUTION Do not connect the output of the TI250 Series Static Inverter to the output of any other inverter or damage will result. Under no circumstance allow the output of the inverter to be connected to ground utility AC power or damage will result. If more than 250 watts of power is required for an installation, a higher power inverter model such as the 500 watt Mid-Continent MD50 should be selected.
  • Page 16: Section 4 Operation

    SECTION 4 OPERATION ELECTRICAL PERFORMANCE The TI250 Series Static Inverter converts a direct current (DC) voltage input to a regulated VAC output; the output is controlled to an established frequency and represents a pure sine wave with minimal distortion. See Table 4.1 specific output and frequency.
  • Page 17 Short Circuit And Over-Current The TI250 Series Static Inverter 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 375 watts for over 30 minutes (until over-temperature shutdown occurs).
  • Page 18: Section 5 Conformance

    No periodic scheduled maintenance or calibration is necessary for continued airworthiness of the TI250 Series Static Inverter. If the unit fails to perform to specifications, the unit must be removed and serviced by Mid-Continent Instruments and Avionics or their authorized designee.
