Abstract: A transceiver device operatively coupleable with a protection and control device to provide wireless connectivity to the protection and control device. The transceiver device includes: a transceiver unit including an RF antenna; a serial communication port operatively coupleable with a further corresponding serial communication port of the protection and control device; a serial communication bus electrically connected between the serial communication port and the transceiver unit and having a transmission line and a reception line, in operation the transmission line taking a high-level voltage value, when the transmission line is in a stand-by condition, and a low-level voltage value, when the transmission line is in an active condition; a battery unit; and a feeding unit to feed the transceiver unit with a feeding voltage, the feeding unit including a first power supply stage electrically connected with the battery unit to harvest electric power from the battery unit and a second power supply stage electrically connected with the transmission line of the serial communication bus to harvest electric power from the transmission line, when the transmission line is in stand-by condition and takes a high-level voltage value.

Abstract: The present application relates to a coil actuator for low and medium voltage applications, which comprise a electromagnet operatively associated with a movable plunger, a power & control unit electrically connected with the electromagnet and first and second input terminals (T1, T2) operatively connected with the power & control unit, wherein an input voltage (VIN) is applied between the first and second input terminals during the operation of the coil actuator. The power & control unit is adapted to provide subsequent launch pulses of drive current (IC) to the electromagnet, which are separated in time by at least a predetermined time interval (TI), in response to subsequent transitions of the input voltage (VIN) from values lower than the first threshold voltage (VTH1) to values higher than the first threshold voltage.
