The Motorola LSAD-100 is a universal power supply adapter that converts multiple input power sources into stable 28 VDC output for LST series transceivers. This dual-input design accepts either 11–32 VDC or 110–230 VAC, making it suitable for both field and stationary installations. Power input connects via a circular MS3114E14-5P MS connector, while transceiver power delivery uses a 9-way D-sub connector. The adapter handles AC/DC to DC conversion internally, eliminating the need for separate conditioning modules.
