QUESTIONS & ANSWERS
The Mid-Continent 1394T101-3B operates on 11–32 VDC, making it compatible with both 14V and 28V aircraft electrical systems without modification.
Yes. The 1394T101-3B is FAA TSO-C3e certified and qualified to RTCA DO-160G environmental standards, making it approved for installation in type-certificated general aviation aircraft.
The primary difference is the bezel lighting. The 1394T101-3B includes an illuminated lighted bezel for night operations; the 1394T101-7B is the non-lighted variant. Both share the same brushless motor, 3-pin connector, and 11–32 VDC input range.
It uses a 3-pin connector. The compatible mating connector is the MS3106A10SL-3S, which is available separately.
