摘要： In a direct-current voltage-driven magnetic contactor, a main contact is in an open circuit condition in an attraction period of an initial period of excitation by an operating coil, and in a closed circuit condition in a subsequent holding period, and a drive circuit includes a direct-current power supply voltage detecting circuit that gives a start signal when an applied voltage of a exciting direct-current power supply exceeds a predetermined value, a first drive circuit that makes a starting semiconductor switching element perform an ON operation on receiving the start signal, and a second drive circuit that makes a current limiting semiconductor switching element perform a switching operation when a terminal voltage of a charging capacitor reaches the predetermined value.

摘要： An inverter apparatus in which a control power source connected to a microcomputer or a peripheral circuit included in at least one of an inverter main body, a built-in option, and a parameter unit is provided in the inverter main body. The apparatus has an external-power-unit connector via which an external power unit can be connected to at least one of the inverter main body, the built-in option, and the parameter unit. The external power unit connected to the external-power-unit connector is configured to function as a power source that controls the microcomputer or the peripheral circuit included in at least one of the inverter main body, the built-in option, and the parameter unit.
