1. A control console configured for radio frequency (RF) nerve ablation, the control console comprising:
a plurality of channels;
a plurality of RF amplifiers each being dedicated to deliver energy to a corresponding one of the channels;
a plurality of DC power supplies each being dedicated to a corresponding one of the RF amplifiers;
a plurality of power supply relays each being coupled between one of the DC power supplies and an input of the dedicated corresponding one of the RF amplifiers; and
a controller coupled to the RF amplifiers and being configured to:
apply switching signals to control each of the power supply relays to selectively switch on and off connections between the DC power supplies and the dedicated corresponding RF amplifiers; and
apply control signals to each RF amplifier sequentially, one at a time, to deliver energy separately and independently to each of the corresponding channels.
