A wide voltage range is acceptable, from 10.5 - 17VDC rated at 70-100mA (or more) with a miniature coaxial connector.

Actual measurements are 55mA @ 17.5VDC (approx 1 W) and 50mA@12VDC (approx 600mW)

Important: Make sure the center contact of the connector is positive. If you use the wrong polarity, a choke will burn out and need replacing, but the rest of the unit will be intact.
