A transient voltage surge suppressor assembly comprising: a first energy absorbing device; a second energy absorbing device in parallel with the first device; and a voltage sense circuit configured to take the first device off-line when a voltage swell lasts for a duration. The first and second devices may be wired in parallel between a line and a neutral. The assembly may include a third energy absorbing device wired between the line and a ground, the third device also being configured to be taken off-line when the voltage swell lasts for the duration. The voltage sense circuit may be powered by a line voltage or a lower supply voltage. The first device may be more sensitive than the second device. For example, the first device may have a lower clamping voltage than the second device. The first device may be smaller and/or include fewer components than the second device.

Swell sustaining transient voltage surge suppressor

A method and apparatus for mounting heat generating components on a printed circuit board. Components mounted on the printed circuit board that generate heat may alter the properties of the printed circuit board and allow the printed circuit board to conduct current. To stop the flow of current in the printed circuit board, a slot may be used between the mounting points of the component. The slot prevents current from flowing within the printed circuit board.
