HV300 - Inrush Current Limiter Controllers
The Supertex HV300, Hotswap Controller, Negative Supply controls the power supply connection during insertion of cards or modules into live backplanes.
It may be used in traditional ‘negative 48V’ powered systems or for higher voltage busses up to negative 90V.
