Abstract
A power supply control device comprises a controller and power connection circuitry. The power connection circuitry comprises a switchable power connection path between a source side and a load side. The power connection path is switchable to operate in a first operation state or an on-state in which state impedance between the source side and the load side is very low to permit flow of operation current through the power connection path, or a second operation state or an off-state in which state impedance between the source side and the load side is very high to impede flow of operation current through the power connection path. The controller is to operate to transmit at least one type of enquiry signals to the load side and to determine with reference to at least one type of received responsive signals whether a load on the load side is eligible for power supply connection. The controller is to switch the power connection path to the on-state or to maintain the power connection path to the on-state if the responsive signals indicate eligibility for power supply connection.

Abstract
A power safety device (100) comprises a control device (140), a load monitor (120) and a switching circuitry, wherein the switching circuitry is optionally operable in a first operation state in which a power supply side (S) and a load side (L) are connected by a low impedance power conduction path or a second operation state in which the impedance of the power conduction path between the load side and the power supply side is high so that hazardous operation current is prevented from flowing from the power source side, through the switching circuitry, and to the load side. The load monitor comprises circuit arrangements to determine and/or monitor load condition within the first operation state upon detection of a non-hazard load condition or a predetermined safe load condition on the load side.
