The MEF1S0505SP3C is a 1-output board-mount isolated DC to DC Converter with single rail regulated output voltage. The MEF1 series 1W DC/DC converter is used where a tightly regulated supply is required. It is ideal for situations where the input voltage is not tightly controlled. The single rail regulated output makes the ideal choice to power sensors, such as pressure transducers, hall effect sensors and mass airflow sensors.
