A device for limiting the inrush current component of an alternating current provided by an AC supply to a load, the device comprising: an impedance arranged between the supply and the load; a switch arranged to divert the current from the impedance, wherein the switch is connected across the impedance and is arranged such that closing the switch will short-circuit the impedance; an inrush period timer connected to the supply and arranged to activate the switch after expiry of an inrush time period, the inrush time period being a time period beginning upon the supply becoming active such that current is available to be provided by the supply to the load; and a reset circuit connected to the supply and the inrush period timer, the reset circuit arranged to deactivate the switch and reset the inrush period timer in response to the supply becoming inactive such that no current is available to be provided by the supply to the load, characterised in that the device further comprises: a low voltage detector configured to receive an input of an unsmoothed rectified AC voltage from an AC-DC converter connected to the supply, the low voltage detector configured to generate a reset pulse at an output upon identification of the unsmoothed rectified AC voltage being below a predefined threshold; and a reset pulse filter connected to the output of the low voltage detector, the reset pulse filter arranged to trigger a reset of the inrush period timer when the reset pulse is of a given duration. an impedance arranged between the supply and the load; a switch arranged to divert the current from the impedance, wherein the switch is connected across the impedance and is arranged such that closing the switch will short-circuit the impedance; an inrush period timer connected to the supply and arranged to activate the switch after expiry of an inrush time period, the inrush time period being a time period beginning upon the supply becoming active such that current is available to be provided by the supply to the load; and a reset circuit connected to the supply and the inrush period timer, the reset circuit arranged to deactivate the switch and reset the inrush period timer in response to the supply becoming inactive such that no current is available to be provided by the supply to the load, characterised in that the device further comprises: a low voltage detector configured to receive an input of an unsmoothed rectified AC voltage from an AC-DC converter connected to the supply, the low voltage detector configured to generate a reset pulse at an output upon identification of the unsmoothed rectified AC voltage being below a predefined threshold; and a reset pulse filter connected to the output of the low voltage detector, the reset pulse filter arranged to trigger a reset of the inrush period timer when the reset pulse is of a given duration. a low voltage detector configured to receive an input of an unsmoothed rectified AC voltage from an AC-DC converter connected to the supply, the low voltage detector configured to generate a reset pulse at an output upon identification of the unsmoothed rectified AC voltage being below a predefined threshold; and a reset pulse filter connected to the output of the low voltage detector, the reset pulse filter arranged to trigger a reset of the inrush period timer when the reset pulse is of a given duration.
