Catalysis of the transmembrane transfer of a potassium ion by a voltage-gated channel. Catalysis of facilitated diffusion of a potassium ion (by an energy-independent process) involving passage through a transmembrane aqueous pore or channel without evidence for a carrier-mediated mechanism. Catalysis of the transmembrane transfer of a cation by a voltage-gated channel. A cation is a positively charged ion. Catalysis of the transmembrane transfer of a potassium ion by an open rectifier voltage-gated channel. An open rectifier current-voltage relationship is one in which the direction of rectification depends on the external potassium ion concentration.
