The invention is a new transcutaneous power supply and/or recharger device for use with implants, with means for assisting in its precisely centered positioning over the receiver coil of the implanted device, The power supply terminal of the power supply device is complete with three or more satellite sensors or coils arranged around the transmitter coil. The voltage value recorded in the receiver coil is transmitted to the power supply or recharger device via the existing telemetric channel and shows the amount of power being transferred, thereby indicating the accuracy of the reciprocal positioning of the power supply terminal and the receiver coil, because the power supply terminals satellite coils or sensors pick up signals and/or fields that depend on their relative position with respect to the receiver coil. Said difference in signal and/or field is used to visually signal to the operator the direction in which to move the power supply terminal in order to achieve its optimal positioning.
